The orientation of the head for standardized anatomical comparison is important for biological and paleontological analysis. It influences anatomical direction, description, the relationship of soft-tissue, study of behaviors such as feeding by the orientation of muscles versus gravity, and so … Continue reading
Subsequent to my post on Nick Longrich and colleagues proposed new taxonomy for an old oviraptorosaur, there has been some interest about some other oviraptorosaurs, and I felt it would be useful to write up a little post about those … Continue reading
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
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
In my last post, I presented an image representing an oviraptorid with the head essentially completely and distinctly fleshed out. This is partly the culmination of examining likely tissues based on skull-only analogues. Some additional suggestions were made based on … Continue reading
There is something exciting about thinking about Masiakasaurus knopfleri. It’s not just the name’s tip of the hat to Dire Straights’ lead guitar and frontman, Mark Knopfler, or the becoming-more-prevalent use of local language to name the animal (masiaka means … Continue reading
As SVP looms, and its contents include much interesting things, especially in several valuable studies on the soft-tissue anatomy of sauropod necks and heads — but which I won’t further discuss outside of the authors’ own discussions — I figured … Continue reading
Last week, I asked readers to guess the intended identity for a hasty sketch (a doodle, really) of some reptile or other, with the intention of seeing if viewers could get a reasonable guess on the otherwise fossilized animal it … Continue reading
Regardless of interesting things about trionychid turtles, there are odd things about other turtles that bear concern. For now, this is is a quick update on my bird/turtle beak morphologies study, here showing off the full jaw with rhamphotheca of … Continue reading
So today, after spending a relaxing yesterday working on two unrelated projects (one of which was the subject of this comment-heavy post on my hypothesis on oviraptorid diet), Memo Koseman (or NemoRamjet, of DeviantArt, who is a fantastic artist, by … Continue reading
