Don't know how people feel about it, but I don't think we have found the elongated scales on the dorsal of any Tyrannosaur. It is a bit skinny, but I guess it's intentional due to it clearly being a Carnivores design.

how did we come to the 5t estimate on maip macrothorax? is there a paper on it? its "only" estimated at 9-10m wich makes it the same ballpark as allosaurus but its twice the weight? id assume a lot of that is attributed to its broad chest but arent megaraptora known for being light? is maip the outlier because it took an apex role?

We all are sometimes eggpensive it's understandable

# ashen wedge Could Carno’s horns be longer than expected?

Could it be? Yea

Would it be? Depends

Problem is using bovids is that they're quadrupedal herbivores with massive necks and shoulder muscles to accomodate for larger horns wheras Carnotaurus probably wasn't using its horns for anything but display

It still needs to be balanced to run after prey

I think that the horns could have a dual purpose like the Ankylosaurs armor and tail club, although it’s not entirely proven for either, but I think a healthy mix of both options is most likely unless more material suggests otherwise

ancient crystal
#

I like to think carnotaurus could get pretty crazy with the head gear.

Of course horns in animals today vary in size from miniscule and barely extending beyond the bone, to massive structures used for a myriad of purposes, so there's a possibility the horns weren't anything more than what is currently preserved.

ashen wedge
undone rapids
#

Abelisaurs also had pretty robust necks that weren't complete S-shaped like other theropods, which is why some light shoving at slower speeds like that of rhinos may have been possible for Carnotaurus.

Heck, maybe the reason why Carno had such a small skull proportionally was due to it having much more keratin compared to other abelisaurs.

dont say the g word or the alderon clones will kill you joyous

I kind of suspect a rounded horn is particularly useful in any way regarding killing but perhaps the Majungasaurus also used its unicorn horn to spear larger sauropods

ancient crystal
stiff osprey
#

that is a good point I met no less than three people yesterday who called others homosexual in POT after being killed

stiff osprey
#

anyway uh I don't think Carnotaurus's horns had massive amounts of keratin that are outside the trend seen in other animals but it would be reasonable to depict some individuals with larger horns

fossil ingot
queen oar
#

the texture on the horns vary between gnarly and porous, which usually means the sheath did in-fact extend further, as this kinda of texture is pretty consistent on some horned mammals who usually have sheaths longer than the bone itself

Usually, a tight sheath would cause grooves, sometimes pretty small, making the bony horns look pretty smooth to the eye

Although, what would definetly be helpful is if we had any study on the histology of Ceratosaur horns. Since, frankly, the best way to understand a structure like this is to understand how it looks like from the inside. To be frank... We do actually need a study on the histology of all horn and/or horn-like structures in Dinosaurs in-general.

At least with the horncorns alone, horridus’s are more robust at the base and seem to have a gradual downards curve by the tip

Prorsus’s are much shorter and usually tend to be more straight

#

Evidence what I said was correct?

In an animal, the horn sizes will vary enough that a bare minimum is established while a maximum is tentative but kind of there. This goes for shape as well

Using it as a distinguishing feature between species is troublesome especially when we have previous instances of such (Rubeosaurus-Styracosaurus)

I only focused with horncores here because someone asked about it. Again, they do vary and it should be accounted for 100% when discussing ceratopsians, but there is a pattern that differs from both species

Reaction time is something that would probably see the most variation in terms of fishers/small game hunters, and some of said prey items

Food pyramids are not analogous to food webs and only vaguely hint at the potential relationships between animals in different trophic levels.

Any small carnivorous mammals in hell creek would be above the largest edmontosaurus in a food pyramid.

oh alright, that makes sense

so the likes of rex and nano would be tertiary?

and does tertiary = apex or nah?

No, the same individual

A T.rex is a secondary consumer when it eats an adult trike, but a quaternary consumer when it eats a Nanotyrannus that ate a dromaeosaur that ate a baby trike

Yeah, that's what happens when you try to over simplify ecosystem dynamics, which is what food pyramids do.

Once you've seen, "Healed bite marks on Triceratops mean that Tyrannosaurus always failed its hunts and was more often than not killed, but unhealed bite marks only mean scavenging and there is no room for uncertainty," as a genuine take on THIS discord you unfortunately start looking at any amount of credit given to prey animals with suspicion

That plus, "Hunting Edmontosaurus and co. was so impossible for Tyrannosaurus, that they'd sooner cannibalize than look in a herbivore's direction."

Ngl only reason I’d say a rex wouldn’t devour an anky cause it doesn’t look appetizing the tail club iirc wasn’t even good for combat as in it wasn’t that good for defense against rex it didn’t hit that hard and despite its armor a rex is very capable of biting through it

Probably referring to this: "The limited range of movement for ankylosaurid tails also argues against its origin as an antipredator weapon." https://royalsocietypublishing.org/rsbl/article/18/12/20220404/63066/Palaeopathological-evidence-for-intraspecific

In reality the primary limitation of tail clubs was their lack of flexibility, as they would struggle to hit anything very far in front of their hips and had extremely limited vertical flexibility, leaving their heads fairly vulnerable. You could maybe argue the limited range of motion reduced how much time/distance they had to put more force into their swings but tmk study on that still suggests that they were quite powerful.

Thyreophorans were able to turn well so it's not like an Ankylosaurus would have a completely defenseless head, but Ceratopsians were also able to turn quite well and yet we know T. rex still preyed on Triceratops in spite of its also very impressive armament.

But its a common sentiment and I wouldn't doubt one held by somebody that might read over this conversation in the next day or two.

thorn grove
# full lagoon Fair, I suppose, but like you said, it likely still would have been sufficient.

I agree, as does the article I cited: "There is little doubt that the tail club could have been used in defence when needed, but our results suggest that sexual selection drove the evolution of this impressive weapon."

I know it's not really the point you were making anyway, but I wanted to introduce a limitation to Ankylosaurus that allows it to be compared to a Dinosaur we know T. rex did prey on. By doing so we can establish that Ankylosaurus was probably not immune to predation despite the lack of direct evidence. I feel too much discussion on Ankylosaurus focuses on its mass or vague assertions about how strong its tail was.

Incredibly educational

thorn grove
# full lagoon It would require a tall predator to bend down a bit which might help said animal...

T. rex probably didn't need to flip it tbh, its head and neck were an appropriate size for it to just bite them regardless and they also happen to be the areas least-easily defended by its tail

On the other hand I do agree its small size actually makes it harder to approach in a way since unlike large Sauropods, for instance, it would be more difficult to get into 'blind spots' in its defense

ancient crystal

No, flukes/caudal fins are necessary for most forms of swimming that utilize the tail in some way, they help stabilize the animal in the water. The specific shape of this structure determines if an animal is more suited for high acceleration and maneuverability or for speed.

# charred hearth what type did mosasaurs have?

They had a heterocercal tail, but opposite to the arrangement you see in most non-teleost fish.

Heterocercal tails (or tails with unequally proportioned tail flukes/caudal fins) in said non-teleost fish help provide lift because the larger fluke is the top one. Mosasaurs, having the opposite arrangement, are theorized to have been very buoyant and thus needed an additional downwards force to aid in diving.

If you're asking about Caudal Fin Aspect ratio, which simply put is what correlates to speed or maneuverability, mosasaurs had a low aspect ratio which correlates to maneuverability

how flexible would mosasaurids be? would it be similar to modern day monitor lizards?

Well they aren't jellyfish.

But they're the worst things ever, I'll tell you that. I've been on multiple shark tagging trips where all you'll see are Man O' Wars drifting by, getting caught in our lines and other fishing gear, which we then have to remove them from and because they're gelatinous they kinda just fall apart and its super gross.

That and they can kill you.

They're actually probably less solid than your average jellyfish now that I think about it. Horrible death goo balloons

is it true man o wars can get longer then bluewhales?

No, think that was the lion’s mane jellyfish

charred hearth
#

ah, alright

ancient crystal

Not sure about man o wars, lion mane jellies can and by a decent margin.

Well to think the largest predator on earth hunts almost exclusively the smallest possible prey
