Is Mimicry among cats, like Tigers mimicking bovids and House Cats mimicking birds to name a few an ancestral trait or independently evolved?

If it's ancestral, is there a possibility that Saber-toothed felids could mimic prey as well? I know there wouldn't be proof for it directly but seeing as modern felids can do it wouldn't it stand to reason that now ancient felids could too?

Domestic cats clicking usually tries to imitate the octave of bird calls, which will draw them closer regardless of how the cat actually sounds, as well as cat clicking being able to mimic squirrels better than how they mimic birds.

I don't know how often it's used but I do know that tigers mimic cows and deer and then proceed to have a successful hunt.

I think it needs more research but felid mimicry is successful at times and it's just a matter of if the felid learned it from its parents (as I read somewhere cats without parents that mimic don't end up mimicking)

I think the main thing halting research on domestic cats actually having successful hunts using mimicry is that they are kinda invasive everywhere so you can't just let a cat loose, and mimicry only happens in some cats

Also the fact that nobody has a real motive to research that kinda thing because I think the most we got from it is "my cat clicks when it's near squirrels and birds and goes into a hunting mood"

I feel like the "dinosaurs didn't have lips" crowd is mostly a bunch of people still hung up on Jurassic park because most of the people I argue with about it seem to act like depictions of Dromeosaurids, Troodontids, and Sauropods with lips aren't an issue to their ideas

So I'm confused here universe. Are you tryna have a gotcha moment where you try to tell us in a belittling way that a subspecies of tiger (that used to be the biggest) which has decreased in size significantly in the past few years enough to where commonly cited sources can't keep up cannot beat a lion or are you tryna say that the biggest current subspecies of tiger cannot beat a male lion?

# fossil ingot Everyone has their own opinions so.

True but if we are going off the average individual in which the fights have the average weight,strength,and ovr abilities of their species then i think a lion factually wins but it depends on the specimen eitherway

On average both overlap each other in size, it just depends which random cat you pick off the savannah or forest respectively. But if you're going best of the best it's Tiger all day

Na I’m not talking about captivity the largest tiger ever found in the wild much bigger than the largest lion ever found in the wild

The largest tiger ever recorded in the wild was a Bengal tiger found in Uttar Pradesh, India, in 1967. It measured 10 feet 7 inches long and weighed approximately 857 pounds.

# hardy sentinel Silly goofball question How does an animal evolve a beak from a fleshy snout?

I actually saw something about that recently
https://www.youtube.com/shorts/a9YVHrwGQ88?feature=share

Ever notice how many groups of dinosaurs (and other archosauromorphs) evolved beaks? Well, there's some evidence from chicken embryos that hatching from eggs predisposed them towards it. Egg teeth are the hard bit on the snouts of hatchlings that they'll use to break the membrane and shell of their eggs when their ready to hatch. Lizards, snake...

Agility is one of the most important attributes to consider in a fight between a Tiger and a Lion. A Tiger in the Terai Region of North India and South Nepal averages 518 lbs, i.e 235 Kgs, while a Lion in Kruger National Park averages around 490 lbs, so a Tiger is slightly bigger, Tigers have stronger muscles while Lions have denser bones.

#

Also here's what I was thinking of:

The fourth trochanter was much closer to the hip on Tyrannosaurs. This would allow greater leg movement with less muscle movement, thus enabling longer strides and therefore a higher max speed; a hypothesis supported by comparing the trackways of Hadrosaurs and Tyrannosaurs. The Hadrosaur's musculature allows its muscles far more leverage while moving its legs, however; and this allows them to sustain movement for longer without suffering from fatigue https://www.researchgate.net/publication/292885678_Duckbills_on_the_run_The_cursorial_abilities_of_hadrosaurs_and_implications_for_tyrannosaur-avoidance_strategies

that seems more like it would restrict forward movement rather than backwards
which would be a point against the animation.

An accurate Mosasaurus would have been so much scarier in Rebirth

Bigger things take longer to turn, so now downsize it to its normal size and then you get an Orca sized animal that can still do tons of damage to a boat that can propel itself high out of the water like a shark, but it's smarter and can aim itself better

They’re correct. Pycno is estimated to be much heavier than Carno. Around 3-3.6t. It’s the largest known Abelisaurid. No horns like Carno either

3.6 tons is way wrong...

“At first, it was thought to be a medium-sized abelisaurus with a body length of about 6 to 7 meters and a weight of about 1.2 tons, but after re-estimation, it was estimated to be about 9 meters in length and a weight of 3.6 tons.”

This is still debated in the community. They’ve only discovered the tailbone and part of a leg bone, so no estimate that is given is going to be 100% correct. And the specimen they found seems to be sub-adult.

thank you all

but now I'm just curious if a study or something came out suggesting skull length was the more reliable scale factor

sullen cairn

iirc arbour and mallon 2018 use a something like ~15% estimated discrepancy in body length between 5895 and 8880 which if i'm remembering right corresponds fairly well to some average between skull width and length

#

but i dont think that was ever explicitly stated as the methodology used

thorn grove

no i've been reading that study and it's pretty vague about a lot of stuff

side note but said paper also intriguingly describes zuul's skull as being 4m wide

This is because Zuul is the wide

there's multiple errors since its length range estimate is seemingly based on CMN 8880 having a 26% wider skull than AMNH 5214 even though that's the scale factor compared to AMNH 5895's skull

sullen cairn
#

this reminds of how like a year ago this guy in the pk server entirely unprompted started crashing out over someone saying that CMN 8880 could be below 8t and subsequently had no idea how arbour and mallon even achieved their estimates

#

which led to a remarkably engaging conversation that never really expanded beyond "The 8 metre 8 tonne for CMN 8880 estimate was made by the worlds leading ankylosaurus experts"

i also wish arbour and mallon stated how they're defining basal skull length because they seem to treat it differently from premax-occipital condoyle length (which is bizzare because their amnh 5214 basal skull is identical to carpenter 2004's premax-occipital length for the same specimen, but the 5214 premax-occipital skull length from arbour and mallon is shorter than either)

#

and they actually cite carpenter for the 55.5cm basal skull length which would really seem to imply their basal skull length is premax-occipital (despite the premax-occipital length being later stated as 54.2cm)

By fragile I meant that they are more likely to break off than a other bear claws due to their shape same applies for theri
I'd also like to point out that while yes if you get or anyone gets swiped by a bear claw it's probably gonna tear through you but these class are not really meant for bears generally don't use them that way when they fight it other bears or large animal they usually grapple them and put them in submission then look for a way to bite without getting hit they might through a swipe here and there but it's more for the blunt force than actual slashing it's claws are just bad at it especially when against another bears thick skin fat and fur layers unlike polar bears who have much shorter class which are actually made to tear flesh easily
They are more of a tool to brown bears to help with their foraging as well as their grappling

How come that's the conclusion you thought of it's just slightly less sturdy not paper fragile they can also regenerate as they are mostly likely covered in keratin the study debunked that their was a digger like ground sloths and showed that their claws were made for hooking and pulling things (presumably food which I find hard to believe do to their necks size maybe they were talking about food on the ground )so that why I made the comparaison with brown bears which they too have slightly less sturdy claws than other bears who also have pulling and hooking claws for fishing and grappling

My condundrum with this is.. why would this animal evolve a part of its body to be nigh useless for anything that requires some elbow grease? Therizinosaurids whole thing was big arms and sharp claws, why would it relegate such a valuable tool to something it can flap around to look scary or attractive?
And the whole "Pulling down branches" thing never made sense to me considering that, if it did have a similar build to other known therizinosaurids, it would've had a long neck that extended far past it's claw range.

I just find it hard to believe that a therizinosaurus couldn't slap something, or use its claws for digging into bark, soil and such. I share this sentiment with the Skeleton Crew, (Go watch them if you don't already, hearing actual paleontologists talk about things is quiote refreshing) in that i strongly believe that therizinosaurus' claws were not as practically useless as some believe.

I'm not a paleontologist though, and my thoughts mean nothing to cold hard research done by the wonderful workers.

Makes sense they would have cheeks. Many of them would’ve had to have chewed their food, even if they had mixed diets. It’s like when feathers were introduced and people thought it was ridiculous until the fossils made it undeniable. Herbivores especially would need a from soft tissue “cheeks” to keep plant matter from falling out while chewing. Animals with complex chewing motions (like ornithopods) needed that kind of structure.

First of all, if you chew you must have teeth adapted for grinding your food, which plesiosaurs lack. You may consider Plesiosaurs heterodont in some groups like Elasmosaurs, specifically Styxosaurines as they developed extremely prolonged teeth that I'd call fangs, they completely lack blunt teeth to crush and grind something.

Second of all, you also need some uncommon jaw mobility in order to chew your food, which I don't think Plesiosaurs had ?

stable stream
#

To my knowledge, plesiosaurs had conical, pointed teeth to pierce / hold prey in place. Styxosaurus got those "fangs" to snatch slippery prey like fish and cephalopods and had no `blunt' surfaces to crush with. Elasmosaurids had slow tooth formation cycles, meaning that tooth wear due to grinding had to be infrequent or even nonexistent. So, plesiosaur jaws worked by simple vertical shearing. And lateral / palinal movement ability is characterized by jaws of chewing dinosaurs and mammals. Right? (I remember too many words from Zoology in HS lol)

white matrix
stable stream
# white matrix it was a picture of a tyrannosaur...

Yes, I realize this. But there’s evidence in the Exopaia discovery explaining convergent evolution in jaw-stabilizing soft tissues (“cheeks”) in theropods. They would maintain T. rex's teeth protection, prey control, and jaw stabilization. These are things quite necessary for an apex predator that uses forceful bites as opposed to regular mastication.

I did a quick look through Google, evidently it’s a common misconception, but the ceratopsian frill is definitely not part of the forehead.
Also, I am very completely aware of what a skull looks like I took multiple biology classes, forensics, and zoology with a lesson in this.
I am a biology minor undergrad. What you need to be looking at is a side angle of a skull not a front angle. The front from what you can see on the image you sent is considered the facial orientation. anything beyond that point is no longer the face.

Also yes. The area around the frontal bone is considered the frontal portion / facial orientation of the skull, which creates the true forehead and face. But, ceratopsian frills do not extend from the frontal bone. They extend from the parietal (& squamosal). So it means the frill projects from the rear part of the skull, not from the forehead or facial region. (I didn’t like my prior explanation lol)

No, carcharodontosaurids were usually gunning for sauropods which are usually much larger when compared to other megatheropods and their prey so having a strong neck and a larger head (though they did have to sacrifice some neck movement) than "average" is the result

The paper I attached goes over the second specimen for Taurovenator and a possible explanation for the raised spines

haven't mammals been around for technically longer if you think about it

ashen wedge

stiff osprey
#

mammals appear at the end of the triassic by the earliest, dinosaurs are older

light osprey
#

Are Dinosaurs not a late Triassic thing as well

stiff osprey
#

yes, but the earliest mammaliaforms are norian, while the earliest dinosaurs are ladinian (or earliest carnian)

#

presumably mammals appeared some time after mammaliforms did

light osprey
#

Do we have any crown group Mammalia from the Triassic

stiff osprey
#

Not that i know of, i think it's molecular clocks that put them in the triassic

fluid inlet
stiff osprey
#

no, prob made by pseudosuchians or some dinosauromorph type thing

#

''late triassic'' is a misleading term because the late triassic actually takes up 2/3 of the entire triassic period and early/mid triassic are tiny squeezes of time

stiff osprey
#

these are norian-rhaetian, late triassic

fluid inlet
#

But if they are that big how long did it take them to evolve into that point from whatever dinosaur they came from 🤨

light osprey
#

Not very long

stiff osprey
#

herrerasaurus is only about 5-7 million years after the first known dinosaurs and it already weighs half a ton

also keep in mind the diagram is oversized, the footprint maker was not built like allosaurus

https://en.wikipedia.org/wiki/Silesauridae

Silesauridae is an extinct family of Triassic dinosauriforms. It is most commonly considered to be a clade of non-dinosaur dinosauriforms, and the sister group of dinosaurs. Some studies have instead suggested that most or all silesaurids comprised an early diverging clade or a paraphyletic grade within ornithischian dinosaurs. Silesaurids have ...

I love how the Ichthyosaurs, Plesiosaurs, and Turtles are all a family (or so I've been told). You can really see it when you look past the hell that turtles are basically just short necked Plesiosaurs with beaks

That's an old idea which may not old up anyway (first the Plsio + turtle group and now the whole Archosaurian marine clade).

@thorn grove hey so rex had a longer femur than tibia right?

#

this zhuchengtyrannus had a 89 cm femur and 95 cm tibia
rn im scaling the new maxilla to the old one
if its bigger than that means zhuchengtyrannus size nerf...

#

okay it says both maxilla are the same size

#

BUT that when referencing tyrannosaurus, tarbo and the qianzo whatever that it doesn't look to be fully developed
meaning so far when scaling using its femurs, we got a 8 meter zhuchengtyrannus but with the potential to be a lot larger
Basically same boat as alamosaurus

#

lets hope that unclassified tyrannosaur is just a fully mature zhuchengtyrannus 🙏

#

lets pray for 12 meter zhuchengtyrannus

#

in the new walking with dinosaurs spinosaurus aegyptiacus has slit pupils and i suspect this is because they wanted to give it a more crocodilian appearance and the inference on semi-aquatic ability, but does evidence suggest round pupils instead?

balmy oyster
#

While it’s plausible I feel as if spinosaurs would’ve benefited more from rounder pupils considering it shares its habitat with a lot of other giant predatory and rounded pupils would be overall better for all-rounded vision

Carcharodontosaurus in the movie would be peak

#

mine says something else

The study claims the new one is 460 mm, while iirc the holotype is 63 cm long, considerably bigger, so this translation makes more sense

white matrix
thorn grove
#

"Well first off the easy stuff – we can measure the bones we do have and that gives us a 64 cm maxilla and a 78 cm dentary, though the latter would probably have been a bit longer in life."

https://archosaurmusings.wordpress.com/2011/04/03/so-just-how-big-was-zhuchengtyrannus/

I used image translate instead of copying the text, that may give different results

But yea the new specimen seems to be quite a bit smaller than the old one going by the numbers, I was actually remembering the holotype slightly smaller than it actually is

white matrix
#

so old one is 10 meters, new is 8 ?

thorn grove
#

technically if the new one is 8 m then the old one scales to be 11 but I think Tyrannosaurid maxillae get proportionately larger as they age (don't quote me on that) so 10 seems more reasonable and is roughly what people got from scaling it to Tarbosaurus maxillae

# brave nova Based off current estimates they are 4/5

Isn’t like the ranking 1. tyranosaurus 2. Giga 3. Spino 4. Carcharodontosaurus = 5. TyranoTitan 6. Mapusaurus 7. Acrocanthosaurus 8. Taurovenator ( might be bigger then acro? ) 9. and 10 are like zhucheng, tarbo, tameryraptor, Kenyan Giant, meraxes, Allo Anax, and like a few other carcharadontosaurs

Carcharodontosaurus, Giganotosaurus, Tyrannotitan, and Acrocanthosaurus, are remarkable as being titan killers, as their morphology suggests macro-predation, they likely regularly hunted and killed giant sauropods for food. And they're all grouped in a family called the Carcharodontosauridae, showcasing the family's potency as some of the most p...

Like
Mera is 5.7t
Tauro is 6.3t
Tyranno is 6.7t
Mapu is 7t
Carcha is 7.6t or 8.4t depending on who u wanna scale it off
Giga is 8.6t but then if u wanna use dentary it’s 10.7t
Then with Acro the scaling for it before using the museum mount had it at 6.1t

I also learnt that it could just be about the same size as holotype giga too since apparently the size difference isn’t really that great…

Maybe we’ll find out better when the third specimen comes out in a decade lol

its dumber than your craziest image
the local goverment made it into a dumbass dino theme small park filled with bad mounts and they use Trex for zhuchengtyrannus
they even keep that name "Huaxiasaurus gigantus" which is a quite old name for shant

# white matrix how big is it compared to a rex's?

I believe there's some trex that have a scapular around 90 cm so compare it with them
but also this zhuchengtyrannus also has a near complete leg
so why not use its leg or femur to make a better estimation

so the scapular was
not very normal for it…
unusually large I think

white matrix

could be a different zrex's

sullen cairn
#

i was about to say couldnt they just be different individuals given bonebed

white matrix
#

89 cm femur and 94 cm tibia with thin bone walls suggest it was still growing

#

plus when comparing maxillas it was way smaller

lofty creek
#

so we actually get a 8-meter subadult or just immature and a way larger adult with it…
goddamned single scapular estimate time

white matrix
#

when does the femur get longer than the tibia in rex?

#

12 meter zhucheng is real.... i feel it in my nuggets

lofty creek
#

for that scapular I'd like to suggest it at ~11 metres?
though single bone estimate never reliable

white matrix

id say more like 10

i am too lazy to measure from skeletals but am having a frustratingly hard time finding t rex scapula measurements

likely to be slightly larger than holotype then

it is a big scapula but idk tarbo scapula numbers lol

also info on that Shanyang Shant according to some random archived email that google came up with

Shantungosaurus cf. giganteus
material- (NWUV 1114) two teeth, caudal centrum, humerus (900 mm),
incomplete ulna, partial radius, manual phalanx, partial pubis(?), femur
(1.536 m), distal metatarsal(?), unidentified flat bone (scapula?)
Shanyang Formation or Hongtuling Formation, Shaanxi, China
Maastrichtian, LC
Description- This is mentioned as being similar to the type species, but a
bit smaller. It is actually always referred to in the article as
"Shandongosaurus cf. giganteus Hu 1974", but looks hadrosaurian and
Shantungosaurus was described by Hu in 1973, so I'm betting it's a
misspelling. https://dml.reptilis.net/2000Sep/msg00139.html

lofty creek
#

yes
same thing
the spell system was different
now that's spelled as shandong but shantung was older

thorn grove
#

yea the transliterations have changed a few times

the measurements alone make it seem like it's shant though, that's a massive humerus

it just seems ridiculous for it to be limited to a small part of eastern china in campanian rocks and then randomly turn up in maastrichtian rocks in western china but who knows ig

might be a different species at least

edmonton also survived a long time so thats possible
also Wangshi is a biota, not a formation anymore
it's longer and bigger than u may think
