I am constucting a graphic of dinosaur family tree for a big exhibit on
Chinese dinosaurs to open very soon. In consultation with Philip Currie I
have placed Sinosauropteryx in the Compsognathid line. Does the line
extend
beyond this point and if so when can I end it. Hard to find in any
literature available to me.
As I understand it, the unnamed Santana form and Aristosuchus are also
considered to be compsognathids. I believe that the former was described
in the Canadian Journal of Earth Sciences but I do not know the citation.
O. Rauhut believed Koparion to also be a compsognathid but most other
researchers recognize it as a very basal troodontid.
