Undescribed Ghost Ranch theropod
Somewhere in the Carnegie Museum is a little theropod from the famous
Ghost Ranch quarry, New Mexico. My records indicate it's skull is
similar to Coelophysis bauri but has a prominent sagittal crest.
If anyone knows of this specimen (Museum number, etc) and if it has been
described or is being worked on, I would appreciate any information.
Currently the theropods from the Ghost Ranch are referred to Coelophysis
bauri. Some authors (Hunt & Lucas) have given them the name
The Ghost Ranch theropods range from the juvenile to adult, and two morphs
(possibly representing sex).
Morph 1 -- long skull with smooth crest, long neck, small forelimbs, and
fused sacral spines
Morph 2 -- shorter skull with smooth crest, shorter neck, large forelimbs,
and free sacral spines
Variations within the 2 morphs exist, but this is the first occurence of
a sagittal crest.
