Abstract
Three dentaries of small theropod dinosaurs from the Judith River Formation of Alberta are described and their taxonomy is discussed. Two are referable to the Dromaeosauridae (Dromaeosaurus sp.) and the other to the Saurornithoididae. The structural differences seem to support recognition of two distinct families, Dromaeosauridae and Saurornithoididae, as proposed by some authors on the basis of other structural differences.This publication has 2 references indexed in Scilit:
