Hey bsky! I’d like to share some cool work I recently coauthored that integrates entomology, paleontology, and German cultural history. 🔶🐜⚡️ We discovered a fossil ant in the amber collection of Johann Wolfgang von Goethe! Read on for a delightful story of #museomics and #collectomics. >> 1/

Tree creepers are wonderful birds and this one was being especially obliging in Cambridge yesterday. Their thin beak is perfect for finding and extracting insects from tree bark. #cambridgewildlife #birdsoc_cam #uk_birdwatching

A new species of scrub-ox joins North America's Ovibovine diversity during the Pleistocene!
Formerly classified as a species of Euceratherium, it is now known as Speleotherium logani.

Let’s sketch one of the giants of the Jurassic, Torvosaurus!
Torvosaurus was a genus of megalosaurid theropod that lived during the latest part of the Middle Jurassic and the Late Jurassic. The genus contains two described species found in North America and Europe
