Dr. Paul Sereno hasn’t published much in the last few years. Apparently the reason is because he just finished a monograph on Heterodontosauridae … a real monster at 225 pages. I haven’t the time to review this yet, but there’s … Continue reading
It’s kinda of a mystery, and I’m not sure I can solve it, but…
New news of a new newsworthy theropod dinosaur in the presses. It’s not published in paper yet, although the journal has it available (free) on its website. Because it’s not published (on paper) I will refrain from discussing the taxon … Continue reading
Interdental plates represent another feature of variation in the dental row, and one generally taken for granted by most researchers, and the following illustration represents a crude way to encapsulate some of the variation that occurs in archosaurs. Because interdental … Continue reading
This is the second “Precision in Terminology” post Tetrapods generally have only a few ways to affix teeth to their tooth-bearing bones. While most of you readers may be familiar with socket-toothed implantation (thecodonty), the range of dental attachment varies … Continue reading
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
One of the more interesting non-dental features of theropod dinosaur evolution is the orientation of the pubis. Historically, it was used to help affirm the transition of the modern bird form from that of particular theropod dinosaurs. Back then, it … Continue reading
The humerus (or the anterior propodium) is one of the most complex bones of the limb, next to the femur (or posterior propodium), and various carpal/tarsal bones as they are described in mammals (although that’s largely practical, rather than actual). … Continue reading
Historically, taxonomy has been the playground of débutants and the workshop of balls-to-the-wall genetic systematics. It is the method by which names are applied to organisms, to distinguish concepts of how life can be categorized. We’ve seen different systems of … Continue reading
