Proceedings of the Yorkshire Geological Society, 1906 Anyone who knows a little about the Speeton sections can soon pick up a fairly representative series of their Belemnites, but not of their Ammonites; that demands much time and luck. Such at least has been my experience, for notwithstanding the exceptional opportunities for constant search afforded by several years’ residence almost on the spot, I have

The Anatomical Record, EarlyView.Abstract Sharks possess varied diets and different prey capture mechanisms. As a result, the group exhibits a significant diversity in dental morphology, also reflecting the internal structures of the teeth. Internal dental anatomy points to the existence of three histotypes in elasmobranch phylogeny: orthodont, osteodont, and pseudoosteodont ...
