Coelophysid Distribution & Evolution

[Amtoine Grant <ajgrant@eastlink.ca>]

I was just about to get started on a recreation of some Late Triassic 
fauna. I've decided to focus on a coelophysid & a prosauropod, since 
once seemed to guarantee the existence of the other in most all regions 
they were found. As I understand, the worldwide climate & landscape was 
that of widespread desert & sand dunes w/ little seasonality & arid 
conditions. Given that, my task now is to find out which coelophysids 
existed in different places at that time, how they differed from each 
other and what other creatures they shared their environment with.
I know Coelophysid remains have been found in North America, Europe & 
North Africa. What I barely ever hear mention of are the coelophysid & 
prosauropod remains from here in Nova Scotia. I know a species of 
Plateosaurus has been discovered here, but the most I can find on the 
coelophysid was one little blurb where it was stated that a close 
relative of Coelophysis is know from Nova Scotia. Do any of you have 
info on this Nova Scotion coelophysid?

Also, how many coelophysids are known worldwide from the Late Triassic 
[and Early Jurassic]?Also, it seems coelophysids went extinct after the 
Early Jurassic, except for Lilensternus & Dilophosaurus, which seem to 
be direct derivations of North American species.
