New Paper: Microfossil spiral teeth reveal mesopelagic Cyclothone (bristlemouths) fish evolved during the early Palaeogene greenhouse

Lead by PaleoFISHES Undergrad alum Karinne Tennenbaum (Yale University), in collaboration with Karly Cohen (UW) and Chas Bissell (Yale and Johns Hopkins School of Medicine), we demonstrate that Cyclothone fish have a unique spiriling tooth morphology that can be used to identify microfossils in the deep sea.

A and B are Eocene-aged microfossils; C and D are modern Cyclothone.
