Paravians studies - Raptor Prey Restraint Model by DELIRIO88 Paravians studies - Raptor Prey Restraint Model by DELIRIO88
In attempt to make a more dynamic and anatomically correct version of my leaping raptor delirio88.deviantart.com/art/D…, I finished to focus my attention on the way to hunt of this creature.
The Raptor Prey Restraint model (Fowler et al 2011) is an excellent theory that compares raptor-birds (such as hawks and eagles) hunt behaviors with paravians ones.

The study put in evidence that "the hypertrophied D-II claw of dromaeosaurids was functionally analogous to the enlarged talon also found on D-II of extant Accipitridae (...). Here, the talon is used to maintain grip on prey of subequal body size to the predator, while the victim is pinned down by the body weight of the raptor and dismembered by the beak. The foot of Deinonychus exhibits morphology consistent with a grasping function, supportive of the prey immobilisation behavior model. (...) Placed in context of avian evolution, the grasping foot of Deinonychus and other terrestrial predatory paravians is hypothesized to have been an exaptation for the grasping foot of arboreal perching birds. The paper also describes the “stability flapping”, a novel behaviour executed for positioning and stability during the initial stages of prey immobilisation, which may have been pivotal to the evolution of the flapping stroke."

Did you say that I find so ething accurate only bacause I liked it?

This art is accurate and is gorgeous (to me). Now I have found many inaccuracues in the Saurian T. rex, but I still find it gorgeous.

what was Innacurate about the saurian t-rex?

(apart from the head being too thin)

The corwn of the upper jaw's teeth is to short, about 2/3 the lengh of what is seen in real specimens.

Also the juvenile T. rex shows to long lacrimal horns, while even specimens that are considered to be nanotyrannus specimens by many people have short lacrimal horns (or were found without it).

The reason the teeth aren't as long is because most of the tooth you see in skeletons wouldn't have been visible. They would have been either within the socket or beneath gums. Saurian T. rex is the most accurate depiction of T. rex in media.

wait, wasn't the teeth short because of this? www.angelfire.com/mi/dinosaurs…

the blackish part of the teeth might be the only part showing and a paper did say that the teeth were pushed farther outside the skull

but if it is innacurate maybe they'll give their model a few tweaks?

I've also been wondering that how raptors hunted prey larger than themselves given recent evidence and theories, myself. You wouldn't happen to know if an English version of that article is available, would you?

DELIRIO88 Featured By Owner Apr 12, 2016  Hobbyist General Artist
At the moment with all the info we have about this creatures there's no need to think a predator of larger pray.
Animals such as Deinonychus are just ambush-predators who hunt other animals of the same size or smaller.

Really? I thought there was evidence that they preyed on Tenontosaurus - Deinonychus teeth and bones being found alongside Tenontosaurus skeletons
Reply
:icondelirio88:
DELIRIO88 Featured By Owner Apr 13, 2016  Hobbyist General Artist
Deinonychus are probably scavengers and a huge tenontosaurus is a good opportunity to gain extra-food.
Think about them as vultures. In violent competition with each other for the best part of the dead dinosaur.
Hence the fossil records of teeths and bones near the tenontosaurus.

They could use this on larger prey, like how an eagle would latch onto a deer.
