Re: styracosaurus

Jonathan D Marcot <jmarcot@gas.uug.arizona.edu> asked about
Styracosaurus/Monoclonius synonomy.

Tom Holtz wrote this on the subject last month:

  These two seem to be related, but male and female morphs are known
  for both (Dodson 1990: the various morphs were previously referred
  to various species of Styracosaurus, Centrosaurus, and Monoclonius).

The message I'm quoting contained other reference material for various
ceratopsian systematics.  I'll send it to you in toto if you missed
