The Journey of Banguela


The life of a pterosaur cannot be easy. Most occur in places where there is always a larger predator; even the giants Quetzalcoatlus and Hatzegopterus may have co-occurred with other predators that would have seen them as food. From hatching … Continue reading

Whether Shrink-wrapping


Shrink-wrapping is a process by which a thin film is stretched taut over an object. The closer the film to the object, the tighter the two conform. The term applies the same way when it comes to paleontological reconstruction of … Continue reading

Wrench in the Works of Head Attitude


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

A Few Things About Oviraptorosaurs


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

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

Oviraptorid Head Tissues Described


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
