Oviraptor - Hyena Analogue 2 by povorot Oviraptor - Hyena Analogue 2 by povorot
The redesign of this earlier bone-cracking oviraptoran. [link]
I went for a skull much closer to that of Rinchenia, with the tooth-like palate projection being much closer to that of the ancestral oviraptor. On [link] ' s recommendation, these adaptable scavengers also sport a long, rough tongue, for scouring the marrow out of the previously cracked bones. The species shown here is one of the keystone species of pleistocene eurasia, playing a role very similar to the cave hyenas of our own past. These bone-cracking oviraptors developed during the pliocene, and only began to flourish as many of the more slender-snouted dromaeosaurs began to decline with their preferred prey during the harsh conditions of the ice age. The oviraptors were able to thrive in conditions that other predators could not, as they were able to fully wrest all the nutritional value from a carcass.

I like how you made it look bigger with the fur/feathers all over its body instead of just the arms.

I'm on a dinosaur kick right now and I keep coming back to your dino designs, this guy in particular. Love her.

Thanks, man - I've been enjoying your work on flickr for a while now, and it's nice to know the feeling is mutual!

(Also, this is one of my favourite alternate-dino designs too.)

Well, tyrannosaur coprolites are full of crushed bone, and tyrannosaurs do have much sturdier skull constrictions than your generic carnivorous theropod. Maybe they were so successful because of better carcass utilisation? (Take everything I say about paleontology with a grain of salt, I'm a rank amateur.)

Don't worry - I too am a rank amateur. That could well be a factor towards their success, though...

Thats a really cool idea. Never really thought of oviraptors being specialized bone crushers. I remember that Greg Paul's "Predatory Dinosaurs of the World" mentioned that therapods were less efficient at exploiting carcasses then mammalian carnivores due to a lack of bone crushing ability. I realize that your fictional oviraptorid is meant to be a highly derived member of that group, but has anyone done a study of the mesozoic oviraptor species to see if their skulls perhaps could have generated the forces required to crunch bones?

I'd expect not - but it is a very cool possibility, eh? What if rinchenia wasn't cracking nuts or mussels at all, and instead was, in fact, a mesozoic hyena?

Interesting concept, making the normally piscivore or bivavevore oviraptors an analogue to a very carnivorous creature. Though how would that fare with their heavily derived jaws, and mostly-lack of cutting teeth?

Well, the teeth-like structures are for bone-smashing, but they still sport a sharp, eagle-ish beak (like the terror birds). They'd eat with more of the pinch-tear hawk action then cutting teeth mammal action.
