Re: Kayenta Fm (and Dinosaur Trivia Question)
Could the information you're looking for be found on page 181, THE LITTLE
DINOSAURS OF GHOST RANCH, Edwin H. Colbert, Columbia University Press, 1995,
"Another coelurosaurian dinosaur, not very far removed from Coelophysis
is Ornitholestes from the Upper Jurassic Morrison Formation of
Wyoming...Ornitholestes, a small and modified version of the coelophysis
pattern (see figure 46), is a theropod..."
Also, the Kayenta Formation is a younger formation than the Chinle
Formation, according to Colbert (see above book, pages 7, 176, etc.), who
says, "The Chinle Formation...in which Coelophysis is found, probably spans
the Carnian-Norian sequence, at least in part."
This may not help, but I hope so.
