Tawa - the perfect intermediate by ScottHartman Tawa - the perfect intermediate by ScottHartman
Tawa hallae, the primitive theropod that fills in the gap (both morphologically and phylogenetically) between herrerasaurs and coelophysoids. I'll have a lot more to say about Tawa in the future, but in general I'll say that it shows the order of character acquisition in early theropods was not what I (and I don't think many others) expected.

Very good news, and excellent work as always.
Two questions about it:
- Is there some evidence of dinofuzz on such basal saurischians? I've seen several restorations with dionofuzz.
- The environment: Dry? Ancient forest? Dry season + rain season? So I wouldn't make too many mistakes.

No direct evidence of fuzz in basal saurischians. The inference is based on how similar basal ornithischian fuzz (e.g. heterodontosaurid) is to known coelurosaur fuzz. The Late Triassic in general was very arid (and seasonal), but the Chinle was a bit wetter, with enough seasonal rainfall to support substantial conifer forests.

Yes, I've seen about that fuzzy heterodontosaurid. Looks like a fun critter.
I remember the Chinle Fm. from Doug Henderson's artwork, he painted some very nice scenes indeed, with Coelophysis packs and such.

I still don't understand how people can claim that there are no transitional fossils (and ask not if there are any, but why there aren't any, as if the supposed lack of transitional fossils were an established fact) in this day and age.

I think the whole thing is a misconception - a single fossil (or species) can't be transitional by itself, it's a series of fossils (or fossil species) that show transition. No paleontologist uses the term "transitional fossil" in a scientific sense. I think it's simply an intentionally misleading way of construing the data (like other invented concepts like dividing science into "observational" and "historic" branches, or claiming that macroevolution is between "kinds" rather than species).
