It's not quite IN the cerapoda. It is its sister taxon though.

Since the Yixian Formation was considered a boreal forest what kind of foliage would have been present?

It wasn't quiiiite boreal forest. Boreal forest is a LOT colder (actual boreal forests occur in the northern regions of Canada and Russia). You'd probably be comparing it more to the forests of New Zealand's South Island, or the more alpine forests of Tasmania.

As for particular species, I'll need to double check. But it was very much a conifer-deciduous mixed forest. I also imagine it to be very sparsely tree'd for a dense forest (you see similar conditions in Indonesian rainforests compared to mainland Asian, African and South American rainforests - it's GREAT for spurring the evolution of gliding animals).

My mistake. xD It still showed the "feathers" were at least on basal neoornithischians.

how long were stegosaurus? most specifically stenops and how much bigger was armatus?
thanks :)

thanks :)
Armatus was the longest species and IIRC about 30 feet long stenops IIRC was like 26 feet

What is the possibility of Yi coexisting with Anchiornis and other species like it? They were from similar periods and neighboring Chinese provinces.

Not sure if those two exact genera ever met, but the likelihood of Yi living alongside animals similar to Anchiornis and vice versa seems pretty high IMO.

It's a funny thing that membrane-winged Yi shared its environment with Volaticotherium, the oldest known mammal (a triconodont) that possessed gliding membranes. 'Twas a funny thought that occurred to me.

Anyway, Yi and Volaticotherium did indeed share their environment with Anchiornis. All three were from the same time and location (Tiaojishan Formation, China, 161-160Ma). And they in turn shared the same environment as Tianyulong, which brings me nicely to a question I've got:

I'm trying to find data on a heterodontosaurid from the Kayenta Formation (Dilophosaurus, Scutellosaurus and Sarahsaurus territory in the Early Jurassic of Arizona). What bothers me is that there are several papers (1985, 1986, 1997 and 2012) that actually refer to this heterodontosaurid, and the 2012 paper by Sereno has leaked a little bit of info about it (it was moreso about heterodontosaurid dentition, jaw mechanics and implied diet - turns out they were strict herbivores after all). It's apparently related to Tianyulong, and it's supposed to be our most complete "echinodontine" to date, in even better condition than the other North American one, Fruitadens. But it only ever provided a pic of its dentary bone to compare it with the other taxa. The kick to the shins in this case was the paper simply said (I'm paraphrasing here) "we'll talk more about it another time".

My problem is that I know there's a good set of data for this taxon that exists somewhere out there. It's a taxon already well established in literature and is apparently in very good condition. But I cannot for the life of me find anything more than just brief remarks where it's discussed for a brief moment before being completely sidelined and forgotten about. Does anyone else know of this taxon? Are there more pictures, preferably of postcranial remains? It's been three years since its last mention by Sereno - has it even been described yet? And if it has, what's it called?

Tl;dr does anyone here have any more information on the "Kayenta Heterodontosaur" than I'm currently finding?

What was Acheroraptor's intelligence comparable to in modern bird terms?

I don't think any research has been done on Acheroraptor's intelligence (we only have a pair of jaw fragments from the genus, remember).

What critters should come through an anomaly that leads to early cretaceous Oklahoma 115 mya? I have so far, acrocanthosaurus and sauropseidon.

Tenontosaurus, Deinonychus, Microvenator, Aquilops, Zephyrosaurus, and Sauropelta are also from that general time range and location.
