RE: Young rex, triceratops...

I attended Mark Goodwin's talk on the littlest _Triceratops_ at the Lawrence
Hall of Science on November 10, 2005.  He had a cast of the little trike's
reconstructed skull and showed photographs of other more fragmentary
juvenile specimens.  The little guy has big eyes and little horn nubs, and
intermediate specimens sport caudally directed horns prior to assuming the
adult orientation.  

Casts of the little skull can be seen between the _Styracosaurus_ and the
adult _Triceratops_ skull casts in the "Display or Defense" ceratopsian wall
in the American Museum of Natural History's traveling show, "Dinosaurs:
Ancient Fossils, New Discoveries."

An ontogenetic series of _Triceratops_ skull specimens is on display in the
new "Horns and Teeth" hall at the Museum of the Rockies in Bozeman, Montana.
Step aside, _Maiasaura_ and _Protoceratops_ -- you're not the only
ontogenetic series on display.

Mark Goodwin expected his paper on the littlest trike to be published soon
in the Journal of Vertebrate Paleontology.  WFTFP.   =%^P

I don't know how many juvenile _Tyrannosaurus rex_ specimens are known, but
some excellent _Nanotyrannus_ (considered to be young _T. rex_ by many)
specimens have come to light, including the Cleveland Museum of Natural
History specimen, and "Jane," who resides at the Burpee Museum of Natural
History in Rockford, Illinois.  See    <http://www.visitjane.com/temp.cfm>
