RE: Journal of Paleontology Papers

If I'm not wrong, possible heterodontosaurids come from Portugal (Trimucrodon 
cuneatus), and Argentina (unnamed early Carnian form, Báez et al. 1998, 2001). 
The United States form could be a late Jurassic heterodontosaurid related to 
Echinodon becklesii (Galton, 2002).
