RE: Tanycolagreus vs Coelurus

Seems like the differences are pretty subtle, but the key point is
that _Coelurus_ wins.

Dammit! I'll have to do my phylogenetic analysis all over again. I had _Coelurus_ coded as "hypnotic gaze: non-swirly (0)". Sheesh!

Anyways, you can find the original description of _Tanycolagreus_ (as a pdf) at:


Carpenter, K., Miles, C., and Cloward, K. (2005). New small theropod from the Upper Jurassic Morrison Formation of Wyoming. Pp. 23-48 in Carpenter, K. (ed.) The Carnivorous Dinosaurs. Indiana University Press, Bloomington.

In brief, Carpenter &c find that _Tanycolagreus_ is "most similar to _Coelurus_", but is more primitive in a number of anatomical features.
