More new ceratopsid finds
I just got back from some research out in the Black Hills of South
Dakota--many new finds to report!
The main purpose of my trip was to examine a Torosaurus skeleton.
Unfortunately, erosion took much of the skull. However, there are many
vertebrae, and much of the hind and fore limbs. The unguals are in
excellent shape. My preliminary work suggests that there may be
proportional differences between Torosaurus and other ceratopsians. . .
There were many cool pathologies on this specimen, also. Three of the
caudal vertebrae show a very nasty infection in the centra--the bone is
bubbled and warped. Also, there is evidence of theropod bite marks on
some of the skull material. The specimen has many bones not preserved in
a Torosaurus before!
I also made a stop at the Black Hills Institute, to see some of their
new ceratopsian material. Of particular interest was Kelsey, a very nice
Triceratops horridus specimen. The skull is absolutely incredible, with
just one of the horns missing. The rest of the bones are in good shape,
While there, I was also shown a small chunk of bone. Lo and behold, it
is a TINY ceratopsid orbital horn--probably juvenile. It measures about
four inches or so in length, with all sutures and sinuses perfectly
preserved. Unfortunately, that was all that was found. It is about half
the size of the AMNH specimen that Brown and Schlaikjer published in the
I took many, many measurements and photographs for all of these
specimens. They are available upon request, through e-mail and mail. I
will be sending out copies to those I have promised once my prints
