Re: Jane The juvy T. rex
I attended Paleofest at Burpee a couple of years ago, where I purchased a
dandy replica of one of Jane's teeth, complete with root, molded with
matrix. It looks like bonded bronze.
Below are my comparisons of this Jane replica with a replica of a large
_Tyrannosaurus rex_ tooth with a complete root. All measurements are
approximate. The two "diameter" quantities for each tooth were measured at
the widest points.
Jane: 10.0cm x 2.0cm x 1.3cm; 20 serrations per cm
Other: 27.0cm x 5.5cm x 3.0cm; 15 serrations per cm
I would say that Jane's tooth looks very tyrannosaurid to me, though a bit
more angular in cross section. I'm sure we'll learn a thing or two about
_Tyrannosaurus_ ontogeny from this beautiful specimen.
And if you just can't WFTFP, see the illustration of Jane's skeleton at
http://www.visitjane.com/media/janeskel.pdf . It is intended for
children to color, but it should be generally correct.
