Pegomastax africanus by T-PEKC Pegomastax africanus by T-PEKC
Reconstruction of the described last month heterodontosaurid Pegomastax africanus. It lived in South Africa, during the Early Jurassic epoch. The configuration and distribution of integumentary structures is speculative.

The holotype of this animal is a partialy preserved lower jaw. The rest of the animal was reconstructed as it follows: skull is based on that of it's close relative Manidens condorensis; body - after Tianyulong confuciusi and Heterodontosaurus tucki.

This is my second drawing for the ongoing collaborative project at Hell Creek's forum - [link] .

Wow this is absolutely amazing! The pegomastax is such an amazing creature don't you think? It's one of my two favorite dinosaurs the volosorapter and well you know.

Thanks!:)

Every animal is amazing in its own way. As for the Pegomastax to me it's just another very fragmentary heterodontosaurid, though indeed it adds new information for the clade it belongs to. What you see in this drawing is more than 95% speculation. My Pegomastax is reconstructed after some of its close relatives, and even those relatives are known from very fragmentary remains.

BTW, it's Velociraptor, not "volosorapter".;)

It looks like some weird combination of a lizard, ugly dog and a giant rat :D .

I totally see the rat part - the integument.

Wow, that's probably the ugliest animal that ever existed.

I don't know if it's ugly, but in my opinion all heterodontosaurids have that scary look. They look far too dangerous for small herbivourous animals.

Glad to know you love its face. I was worried that I drew it a little bit distorded.

Interesting portrayal.
Would the integumentary structures count as a type of simple feather? (though of course evolved separately from the feathers of theropods).

T-PEKC Featured By Owner Nov 21, 2012
Thanks.

I guess it depends on who you're asking, but in my opinion it's not right to call them feathers. Sure, they are probably homologous to theropods simple feathers, but there is still no paper that deals with the nature of these ornithischian integumentary structures, so we don't know yet if both structures are the same. Personally, I prefer to call them filamentous integumentary structures.

I guess calling them filamentous integumentory structures would make more sense, as they probably evolved independently from feathers.

And here's how Pegomastax would look in JP!

Nah... too much ornithischian fuzz. I doubt that JP could go any further than this - [link] . Though, even the one in the link, is already pushing the limits. :lol:

True. Well, we'll see how far they're willing to go in JPIV.

When it comes to accurate reconstructions I hope they are willing to "Boldly go where no man has gone before". :lol:
