New #ScienceCommunication website blog from me. Here, I reflect on a framework inferring ecological traits from shark teeth from my PhD & look at 2 fascinating studies that took it further than even I thought possible 🦈

New studies highlight the use and limitations of teeth as ecological proxies in ancient sharks — Dr. Jack A. Cooper
In 2023, I published my first PhD chapter as a scientific paper – producing a framework to infer shark traits from tooth measurements. Being based on living sharks, I would subsequently apply this fra...

Delighted to have the first paper of my PhD published today in @peerj.bsky.social on a wonderful lungfish tooth plate from Morocco 🐟🦷! With @draliceclement.bsky.social, @merlegreif.bsky.social, & colleagues. peerj.com/articles/193...
A new origin of the ‘modern’ lungfish dentition revealed by taxonomic overlap between Devonian and Carboniferous dipnoans
Lungfishes (Dipnoi, Sarcopterygii) initially radiated in the Early Devonian, and reached the apogee of their diversity during this period, especially with regard to their dentitions. Following the end...
