The trilobites are the big draw at Mt. Orab. It's full of Flexicalymene and Isotelus.

This was a nice surprise - a scolecodont jaw from a polychaete worm.

That you very much Aline. This specimen was most definitely mislabeled. Boney fish aren't my expertise. Do you know anyone who might be know the proper genus of this specimen? Someone suggested Knightia but it didn't come from the Green River Formation.

Welcome back to #fossilfriday

Here is the fresh water Dastilbe elongatus. This specimen comes from the Lower Cretaceous (Aptian-Albian) Santana Formation in Serra de Araipe, Brazil. The Santana Formation is well known for its exquisite preservation of pterosaurs fossils.

Animated Scutellosaurus!! (Also Dilophosaurus, prosauropods, and dimorphodonts, but I think I've seen animations of all those before...)

Photograph of the holotype and only known specimen of the hauffiopterygian leptonectid, Xiphodracon goldencapensis (ROM VP52596) from Golden Cap, between Charmouth and Seatown, Dorset, UK. The skeleton is exposed in ventrolateral view. The skull has been fully prepared free of matrix whereas most of the skeleton is still in matrix. The left (upper) forefin has been prepared so that it is
three-dimensionally preserved and projects upwards. Scale bar (lower left) is 20 cm.

#whalewednesday The spectacular early toothed whale Xenorophus sloanii from the Oligocene (~28 mya) of South Carolina! This is a critical transitional fossil, known from about a dozen skulls and partial skeletons. Read more about Xenorophus here on my blog: coastalpaleo.blogspot.com/2024/03/the-...

#paleoctober2025 day 9 : Protobalanus spinicoronatus !

Despite its name, this animal is a devonian mollusk, more specifically a basal polyplacophoran. You may know its current day relatives as little criters on the beaches called "chitons" (that are not slugs with shells nor crustaceans).

A drawing of Protobalanus spinicoronatus, a flat oval-shaped mollusk with no distinct head and armored plates and also spikes on the body's edge.

Circled are two cranidia from the trilobite Tricopelta breviceps. They are less common than trilobites like Flexicalymene and Isotelus within the Cincinnatian Series. This specimen comes from the Upper Ordovician (Richmondian) Liberty Formation in Franklin county, Indiana.
