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.

Out now in Contributions from me and @gilespalaeo.bsky.social, a deep dive into an early member of the sturgeon and paddlefish lineage. Bear with me, but there’s a long backstory highlighting uncertainty about the anatomy of living species and how well-studied fossils can still yield new insights.

Osteichthyans--the bony fishes--are by far the most diverse group of living jawed vertebrates. Two papers out today in @nature.com feature remarkable new Chinese fossils that paint a picture of substantial morphological diversity among stem osteichthyans.
