Thescelosaurus amendment

By
Not too long ago I did this: tomozaurus.deviantart.com/art/… displaying what I considered to be three equally possible alternatives in integument for basal ornithopod Thescelosaurus. Well, as per an abstract for this years meeting of the society of vertebrate palaeontologists all three are now out of favour for something like what is illustrated here.

Note that this is taken from the abstract only, so full details will possibly change this even more, and it is unknown exactly what the animal from the paper's affinities are (beyond basal neoornithischian or ornithopod) so Thescelosaurus may have shown variation on the basal condition, but this is the best we have for now.

The abstract describes a basal neoornithischian with simple "filamentous feathers, as well as compound feather-like structures comparable to those in theropods" as well as a scaly distal tibia and feet resembling those of euornithes and a scaly tail with "large imbricated scales on its dorsal surface".

Compound structures? Wow! Any risk of misinterpretation?

Heard about this on Hell Creek. Very interesting stuff!

 

Also, did the abstract mention any specific areas on the tail that were scaled?

Other than the enlarged scales on the dorsal surface, no. Going to have to wftp on that one.

Haven't heard about this, but.... WOW! Just WOW! So looking forward for the paper. It would be interesting to see the implications of this paper applied to scaly hadrosaurs.

Anyway, great work as usual, Tom!

 Are you kidding me? That's just dreamy! Where are the abstracts available?

I don't think they are free access, I got my copy from a semi-private Facebook group. If you PM me with your email I can send them to you.

It's Thescelosaurus-ugly in a very nice way ;)
