teeth/serrations

[ronbuckley <ronbuckley@fuse.net>]

I have been watching the string on teeth/serrations. There were some
strings last year on determining the differences between albertosaurus
and trex. I have a jpeg of two four inch teeth side by side and one take
from the root view with them side by side. I believe there was also some
conversation about the shape of the serrations and the number per inch.
I would appreciate any help in  identification. Thanks, Ron
