Following all that work I’ve been doing on anatomy in oviraptorids, it should not come as a surprise that I am looking for ways to effectively represent this amassed data in digestible chunks. I don’t always want to write novellas … Continue reading

A Definition for “Heterodonty”

Teeth in jaws are generally graded by a useage of “heterodonty” versus one of “non-heterodonty.” In some groups, teeth that are actually identical in two spectra (form and size) are termed isodont (literally, “same tooth”) and could reasonably pass for … Continue reading
