Also, still breaking from the next post on oviraptorosaur diet (which will concern the group commonly referred to as “caenagnathids,” but also some outlying taxa and oddities involved). This will begin a series that will allow me to show off technical illustrations I’ve produced over the years (some for papers, some not). We’ll see what people make of them.
The shapes of the rhamphothecal coverings of oviraptorid beaks is a topic that has elicited very little scientific discussion. It is therefore interesting that when the topic has come up, simple arguments are fairly easy to come by, and they fly in the face of conventional illustration. Here is something I threw together a while back to describe a potential rhamphothecal arrangement for oviraptorids (every single taxon shown is a member of Oviraptoridae –and note how each one is so very different from one another in cranial and crest shape!).
Spurred on by Matt Martyniuk of DinoGoss, whose post on the description of a new oviraptorid, Banji  (not shown above) led into a thesis that has so far fallen under the radar by University of Oslo PhD candidate Stig Jansen .
