Ein neuer Blogartikel von mir über Macrospondylus bollensis (traditionell auch Mystriosaurus oder Steneosaurus zugeordnet), das häufigste Meereskrokodil aus dem Posidonienschiefer von Süddeutschland. #paleobio #krokodile #thalattosuchia #fossilen #Paläontologie 🧪

F I G U R E 9 Histological overview of the pathologies (indicated by purple triangles) observed in the large skeletally immature Macrospondylus bollensis individual (SMNS 97275), in both the femur (a–f) and tibia (g–i). (a, b, d, e, g–i) Consists of abnormal, poorly organized tissue which are highly restricted/localized in area and bounded by successive LAGs. (b, c, f) In the femur, this layer stretches into a large mass of cemented, disorganized secondary osteons. (b) The transitional zone where the abnormal tissue converts into the osteon mass, indicated by a light green triangle. (b, c) The hyphenated black line traces where this mass protrudes into five inner layers. Scale bars: (a–c, g) 500 μm and (d–f, h, i) 200 μm.

Fossilized skeleton of Cricosaurus bambergensis on a limestone slab.
Five years ago, I published my very first paper together with @dinosven.bsky.social, @drmarkyoung.bsky.social & @palaeo3d.bsky.social. We described and named Cricosaurus bambergensis, a marine crocodile relative from the Upper Jurassic of Bavaria.
