You could just add in some category descriptions, so like "Thyreophora" would be the name, and under it would be "armoured dinosaurs" or something. "Marginocephalia" would have "horned dinosaurs", and "Ornithopoda" would have "Mesozoic cannon-fodder" or w/e you'd deem suitable.

I have to LOL at Mesozoic cannon fodder!

Is the inside of the mouth of this Tyrannosaurus accurate?

It seems interesting to me.

No. That kind of mouth is common in non-archosaurian reptiles and amphibians, but it just doesn't work for archosaurs. Though both birds and crocodiles have choanae, they are much less obvious and differently shaped- In birds they are simply slits, in crocodiles they are barely visible holes. I recommend looking at the mouths of birds for the overall layout and appearance, and at a palate of T. rex for the location of the Choanae.

What are the differences between epidexipteryx and yi qi other than yi qi's wings?

The skull also looks different to me (at least in the reconstruction I saw).

Yi qi is also a small bit larger by about 216 grams based on both of their estimated weights. As for the wings, Epidexipteryx is now theorized to have the same wing membrane based on Yi qi.

It's looking like grass had its origins in Mid-Late Cretaceous India. I think there was some sign it reached the mainland (I think it was Pakistan) by the end of the Cretaceous, where they discovered hallucinogenic fungus spores among it as well.

I'll have to double check this though.
Pakistan was part of the indian insular landmass during most if not all the cretaceous IIRC.

And overall, grass developed and was confined to the indian insular subcontinent at the time, its later spread has to do with both the K-T event decimating Pteridophyta diversity aswell as the subcontinent coliding with asia, which in turn also created the himalayas.

Weird question but did basilosaurus produce milk like a modern whale does? .___.

Can I get a list of dinosaur species found on US states west of the Rocky Mountains, excluding Alaska and Hawaii.

Yeah.

Milk is basal to all placental mammals IIRC. There is no reason why Basilosaurus did things differently from modern whales or its terrestrial relatives.

Also, I'm not aware of any dinosaurs known from the west side of the Rockies.
