Recall my earlier post on Daemonosaurus chauliodus. At the time, I thought this was a pretty silly dinosaur to provide a reconstruction for, since for the most part I agreed with the authors’ reconstruction, it matched the skull as i … Continue reading

The Enfluffening
As we dig deeper into the past and our investigative techniques broaden and our perspectives with it, biological aspects of ancient life become more and more interesting. Of the most visual of these is the presence of non-scaly integument in … Continue reading

Oviraptorid Jaw Muscles Described, Part 3
In the previous two posts (part 1 here, part 2 here), I discussed the shapes and sizes of the muscles and their origins and insertions of the oviraptorid skull. I deigned to provide the basis of the muscles mapped to … Continue reading

The Cookie Maker
I produced this image above intended to eventually add it to my growing list of “Incredulous Teeth” series of posts, but never fully finished that. The impetus faltered and relative brevity of research on the anatomy of the taxon hampered … Continue reading
Oviraptorid Jaw Muscles Described, Part 2
In the last post, I discussed the one jaw to cranium muscle that isn’t a depressor that bears on its mechanics (m. depressor mandibular, or mDM) and the palatal and psuedotemporal groups of muscles (m. pterygoideus and m. psuedotemporalis, respectively). … Continue reading

Oviraptorid Jaw Muscles Described, Part 1
Here follows a small, basic and minor depiction of the jaw muscles of an oviraptorid, largely specifically based on landmarks provided by the extant phylogenetic bracket (EPB) but also informed by examining for cranial landmarks in which these muscles typically … Continue reading

Not Sure If a Chaoyangopterid … or Just a Basal Azhdarchid
So, there’s a little something interesting that popped up while doing research on the systematics of pterosaurs. First, There’s not a whole lot we know about the skulls of a particular group of pterosaurs, the Chaoyangopteridae; and second, there may … Continue reading
More Bird Jaws…
A quick post, on what I would prefer to be a “big post” day, due to focus on my oviraptorid study and other projects (but still about jaws and stuff). This one is also about jaws — surprise! — in … Continue reading
