also another question, would patagotitan fit into the game as a official playable? (titan is upsized in this game to be around giga height if that helps compare the sizes)

patagotitan lived with tyrannotitan and likely got hunted by it prob. maybe not healthy adult patagotitans tho, unless the tyrannotitan decided to gang up on adults, but for game balancing itd probably be fine as the first official 6 slot prob. or the tankiest 5 slot

I mean, Titan Needed an Upsize
It already looks like thid next to Spino and Rex
Now imagine POT Rex and Spino xd

Titan is around 13-13.2m ingame
Which is about. A 1.4-1.6m Upsize

I also saw someone say acro beats giga because "giga relied on packs for hunting and couldn't do much solo but acro could hunt sauropods on its own"

I feel like the only theropods that realistically beat spino are rex, giga, carch, mapu, mcraeensis and mabye tarbo and tauro
I might be overestimating spino a little bit idk, but I feel like most theropods arent really beating another who is 2+ tons bigger than them

Dacentrurus (meaning "tail full of points") is an extinct genus of stegosaurian dinosaur from the Late Jurassic and perhaps Early Cretaceous (154–140 million years ago) of Europe. Its type species, D. armatus, was named in 1875 as Omosaurus armatus, based on a skeleton found in a clay pit in the Kimmeridge Clay in Swindon, England. In 1902 the...

That study assumed galloping as the method of quadrupedal locomotion though, which requires a period where all legs are off the ground and is therefore improbable for even typically sized Hadrosaurs let alone the largest species

@charred hearth I don't know if there's study on how Hadrosaur locomotion would vary by size but even ~15 meter Hadrosaurs would have been capable of bipedal locomotion, whether that translates to them specifically running bipedally I don't know but if they were capable of it it would probably have been faster

I mean most tyrannosaurids arent too big compared to the largest hadrosaurs
the average tyrannosaurid is less than 3 tons but the average of the 10 largest hadrosaurs is 9.3 tons so I feel like the tyrannosaurins would have to carry for a lot of it but im not sure if they'd be able to take all 10

what density did you use for it btw? I forgot to scale it but I'll do it once I get off work

#

also I meant 200 cm not 220@thorn grove
iirc the 200 cm was mentioned in the paper describing the 180.5 cm femur

thorn grove
#

fishy and random had a discussion around shant like a month ago and didn't seem to think the 19 t estimate had been downsized and I tend to just assume they'd be on top of stuff like that so afaik it's still valid

A 200 cm femur isn't mentioned in Hu et al. 1973, the first mention of it I know of comes from Brett Surman 1989 which I'll link in a bit. It's a bit confusing in how it references the femur but it states the following: "Shantungosaurus is the largest known hadrosaurid and approaches sauropods in size. According to Hu (1973), the type specimen (IVPP, no number given) is a composite of "middle-sized" individuals. The femur from the figured specimen measures 1850 mm in length. (The largest referred femur is 2000 mm long.)"

If you reference Hu 1973 however, it states that the composite specimen has a 1650 mm long femur and that same number is actually referenced in Surman 1989 in a table comparing Hadrosaurid dimensions. Based on that my assumption is that this 1850 mm number is for the same 1650 mm femur used by the composite but determined by an alternate and atypical measurement method (I.E. along the curves). Accordingly the 2000 mm femur referenced here is probably just the 180.5 cm femur described in Hu 1973 but measured using that same alternate method.

Speaking of Shantungosaurus, I think I've mentioned this once or twice before but I've noticed the apparent size distribution seems to be different between two of the quarries and I've struggled to find an explanation as to why that would be the case.

The Kogou quarry has a well established size distribution from Hone et. al 2014 with an average femur length of ~150 cm, but the Longgujian quarry has universally larger femora

Hu et. al 1973 describes femora of 160.5, 164.5, 165, 169, and 180.5 cm, Zhao et. al 2007 described two femora both measuring 170 cm. There's also a large number of other limb bone elements but cross checking with material from both the Longgujian and other Zhucheng quarries these all seem to correspond to individuals with femora measuring at least 160 cm and many correspond to far larger individuals. I haven't checked all of the other material cuz I'm lazy but the limb bone material at least seems to average over 10% larger than the Kogou quarry material by linear dimensions.

Furthermore when I read about the taphonomy of the two quarries it didn't provide any explanation either (I.E. size sorting); from Hone et. al 2014: "Liu et al. (2010) suggested that the main bonebeds in both the Kugou and Longgujian quarries were deposited by a debris flow that killed and immediately buried a herd of hadrosaurids, and Ji et al. (2011) proposed a similar scenario... The interpretation for the Kugou and Longgujian sites implies that these hadrosaurid taphocoenoses are the result of mass-mortality events, and that their compositions should closely reflect those of the corresponding biocoenoses."

I don't really know what to make of this, maybe I'm just tripping, but I genuinely can't explain this discrepancy unless maybe the papers are just leaving out a ton of smaller material from their descriptions.

yea but idk if it was articulated I had trouble finding much info on it

also while Random made a good point about reconstructions being difficult to make accurately I wouldn't take just scaling from Edmonto at face value either since iirc Shantungosaurus was diagnosed as basically having material like E. regalis but both larger and more robust, the latter point indicating it's probably not just going to be the same weight as a scaled up Edmonto

it's also possible that the two quarries are a few thousand years apart and the species as a whole got larger between those times

I wouldn't call it potent because it takes a lot of compies to illicit a major reaction.

Iirc the little girl in the beginning of the book goes into shock (?) but survives and hammond, a frail old man described as not being much larger than a child doesn't even have that sort of reaction to the venom.

It was like a sort of morphine effect, although in the Lost World (novel) Lewis was still able to feel pain when he was semi-induced in a temporary coma due to falling out of the car I believe

yeah obviously theyre not gonna be 100% accurate every single time but if 2 animals get a 20km/h difference, one is probably a lot faster

I do not understand if dacentrurus was 8-9 meters or less. On each site it says different like 6-7 or 7-8 meters. I just wanna know if stegosaurus was the biggest stegosaurian or not.

#

Yes I know it's because of the missing Fossils but here's what I don't understand: If scientist discover a fossil of a dinosaur from a family that already has basically " the biggest dinosaur from that family" and is also complete to around 70% to 80% for atleast one species and we know the exact size of it, why when scientist find a new fossil and say " oh its from that family" assume is bigger+heavier than the biggest dinosaur that is also the most complete from that family. Why don't they say and assume it's smaller, later when finding more Fossils of the the dinosaur with missing bones/skull etc, actually confirming that it was Larger than the dinosaur that held the record for the biggest from it's family.

#

I don't know if this will be understood but I hate when scientist assume that Dacentrurus is bigger than stegosaurus when dacentrurus is having multiple missing fossils and stegosaurus is more complete than it. Atleast actually confirm later that it's bigger than stegosaurus when finding more fossils of Dacentrurus 🫩

I think that something a lot of casuals miss in evolutionary biology is that an organ can evolve due to a functional pressure (here natural/sexual selection) and yet be used for other stuffs.

The thing is that the Therizinosaurs (but also the mentioned Alvarezsaurs) evolved their claws due to different functions : Therizinosaururs claws (specifically) do not seem the best adapted to slice, scratch or hook and pull, which is still really weird even among Therizinosauria. So, they concluded that Therizinosaurus claw evolution was not driven by predation, nor feeding.

Still, we have no informations on Therizinosaurus ethology and behavioral ecology. Lot of animals still use whatever they can to 1. intimidate 2. defend themselves if necessary.
If Therizinosaurus successfully evolved these hands, it probably is because either 1. the ungual were seen as a trait that was an indicator of a good fitness 2. another feature that was correlated to Therizinosaurus claws was seen as an indicator of a good fitness, which means that individuals with larger claws were better capable of spreading their alleles (gene variant) throughout populations through sexual reproduction.

So yeah, maybe Therizinosaurus claws were functionally useless (still a maybe because we don't know and I personally don't think such animal wouldn't use such claws for whatever it wanted or needed to do) but possibly were related to a trait, or even overall a genotype, that gave better chances at reproducing for individuals with highly developed claws.

Found this

A handful of factors come into play. Pachycephalosaurs weren't very well understood for a long time, around this point they were frequently lumped in with Ornithopods. Additionally, their skulls were pretty well described but actual skeletal anatomy beyond that was exceedingly rare. We know now that their heads are massive for their size, but at the time they were scaled to something more ordinary for other Ornithopods, which lead to an overall larger estimate for the animal (I remember seeing books list them as over 20 feet, compared to a bit under 15 today).

Huh that's genuinely an interesting observation

Yeah ngl i never thought of elongated tyrannosaurid legs being used to help them reach the throat of larger prey items

I'm curious how non-tyrannosaur theropods compare in terms of height

Don't need to be larger than your prey when you have access to the Bites You And You Die ability

The Tyrannosaurus in question: (you need another tactic to hunt ceratopsians)

#

Nono I mean in terms of their prey.

Outside of titanosaurs, how Theropods compare in height to their prey items on average individuals

stiff osprey
#

Large allosauroids and megalosauroids are def taller than their prey unless it's a sauropod (or Stegosaurus)

i think a lot of carchs and co were well positioned at the caudefem of their respective largest sauropods
just from seeing comparison pics, could be wrong there

even then i doubt any morrison predator was hunting stegosaurs taller than themselves

I mean it does make sense to hunt things you are at a good height for

Cats: lol those scrubs can't hunt in three dimensions

Cats simply turn all ground into the high ground

Obi Wan is a cat confirmed. Even when dangling over a pit, he still has the high ground

Why are the scientific names of dinosaurs seemingly by and large easier to say than the scientific names of extant animals?

stiff osprey
#

Are they?

#

I've an easier time saying Hippopotamus than Mnyamawamtuka

coral forge
#

I think its just because you grow up saying common names for animals so you dont get used to the scientific names, but dinosaurs don't have common names so you have to learn the scientific names

stiff osprey
#

There are hard modern animal names, but that's because there are 5 trillion species of them and eventually you run out of good names

if you throw in about 10 million in the ocean, a lot, considering they can lay up to 1 million spawn (although most of them die). Sunfish survive with one of the most intelligent predators in the sea and their survival strategy is literally tasting like rubber

They would probably still be around today if not for us though, despite not having the best of defenses they didn't really have predators.

P sure that's because the main predator of the area, orcas, couldn't hunt them because of how bouyant they were

This is my favorite depiction of Dimetrodon, still very obviously looks a lizard but around the face you can see hints of mammalian features.

what animal alive today would be the closest in niche and hunting style to dimetredon?

probably some kind of monitor lizard

Perhaps a varanid?

Funnily enough, we have evidences of Dimetrodon feeding on freshwater sharks (and mostly semi aquatic animals btw)

ooh, wait, i remember that, couldnt it swim as good as a jaguar or whatever?

coral forge

#

Idk how well this thing would swim but the bone microstructure also suggests a terrestrial lifestyle even though it ate sharks and early tetrapods.

#

So I guess it would snatch stuffs out of water and also hunt stuffs on land.

isnt that what jaguars do?

What is the actual possibility of semi-aquatic dinosaurs having webbed feet? And instead, is it maybe possible they had lobed toes like grebes?

(It's not named Spinosaurus)

little mauve
#

Theroplantigrada encisensis is the ichnotaxon, not Spinosaurus proper as it's from Spain but likely a spinosaur

#

Grebes, like most aves, are highly specialized (underwater pursuit predators) and unlikely to find direct parallels with nonavian dinosaurs. Hesperornithes may have had lobed feet, ecologically and anatomically they are close analogues to grebes and loons
