Fan of fossil fishes. Postdoc at University of Birmingham. Especially interested in using fossil and living taxa to understand the evolution of sharks, rays, and chimaeras. Also paint miniatures very slowly.
For #FossilFriday Pararhincodon torquis: a new species of Cretaceous stem-group collared carpet shark we redescribed earlier this week based on CT data of skeletal fossils (see thread below).
Nice writeup on the @nhm-london.bsky.social website here

Huge thanks to all co-authors for their contributions, without which this sharky detective work would have come to naught. Thanks to Martin Rücklin @naturalis.bsky.social who hosted me, the @ec.europa.eu #MSCA for funding, and @nhm-london.bsky.social for specimens (and prep permission!)

But what about those missing teeth? After looking more closely at the scan data we realised that teeth were there in both specimens: they were just tiny (1-2mm across) and scattered amongst the very similar-looking dermal denticles in the Chalk matrix (small white things in video below).

Like fossil #sharks? Check out our new preprint from work @naturalis.bsky.social where we combine digital/hands on approaches with fossil/extant taxa to describe the 3D skeletal anatomy of Cretaceous collared carpet sharks from the English Chalk. Paper out soon, thanks to all collaborators! 🦈
