A Skull For Rhamphorhynchus, Part Two

My last post on Rhamphorhynchus muensteri‘s skull elicited some dialogue on the dietary preferences one might infer from looking at Rhamphorhynchus‘s skull. This was done regardless of the preservation of gut remains or implied habitus. In preparation of a larger … Continue reading
