Re: Burpee Recollections

My observation on the Jehol dromaeosaurs is simply that all of them as far as 
can be told considering the extensive damage are very similar, and all may be 
one genus, Sinornithosaurus has priority. The diagnoses so far have been 
pretty skimpy. They do differ in time, size, proportions and so forth and 
probably represent species. Much as Buteo includes a lot of hawks and Falco a 
lot of falcons that differ greatly in size and less so in details.
