Aublysodon dentition (Was: tooth question)
Roger et al.,
Here are the only refs. I know of off-hand specifically for
Aublysodon/?Stygivenator dentition. There
are lots more, but these 3 are the first that come to mind
1) Molnar, R.E. 1978. A new theropod dinosaur from the upper Cretaceous
of central Montana. Journal of Paleontology 52(1):73-82.
"All maxillary teeth are similar in form and show 15 serrations per
5 mm along the anterior carinae and 12 to 18 per 5 mm along the
premaxillary tooth...crown 1.2 cm long.....D-shaped in cross
section....differs from T. rex in being shorter anteroposteriorly
and in lacking serrations."
"The first dentary tooth crown is 0.9 cm long...the carina is
displaced medioposteriorly....the serrations therefore running
along the medial surface of the tooth....none are D-shaped in
cross section.....second dentary tooth is 1.9 cm long, is smaller
than the succeeding teeth which range from 2.4 cm - 3.2 cm in length
of the crown....the more posterior of the dentary teeth show
15-20 serrations per 5 mm along the anterior carina, and
14-15 along the posterior."
2) Currie, P.J., J.K. Rigby, Jr., and R. E. Sloan. 1990. Theropod
teeth from the Judith River Formation of southern Alberta,
Canada, pp. 107-125, IN Carpenter, K., and P.J. Currie, eds.,
Dinosaur Systematics: Perspectives and Approaches. Cambridge
Excerpt: "All Aublysodon teeth are less than 20 mm long.....
the maxillary teeth are serrated, laterally-compressed blade-like
They also have a drawing of the pre-max Aubly' tooth.
3) Farlow, J.O., D. L. Brinkman, W. L. Abler, and P.J. Currie.
1991. Size, shape and serration density of theropod dinosaur
lateral teeth. Modern Geology 16:161-198.
I believe Aybly' dentition is mentioned, but presently I can't
locate my copy of their paper to check. (it's probably buried under
the fire-hazard that I call my Stack-O'-Reprints).
Hope this all helps,
