Hi, From time to time I found in Upper Campanian strata of SE Pyrenees some big steinkerns looking much like the American "Deer heart clams". So, my initial guesses are genus Cucullaea/Pholadomya/Arca, especially Cucullaea/Pholadomya royana, but my knowledge of bivalves other than rudists is very limited. Can anybody help? @Ludwigia @fifbrindacier Size of the biggest are 92 x 80 x 68 mm Center one is the best preserved (75 x 67 x 53 mm) : is Finally a different, smaller, specimen from same area and strata. I have no guess about it:

I thought you guys would like to see some Eastern US dinosaur material. This comes from the. Phoebus Landing site on the Cape Fear River. The fossils are actually found in a reworked gravel on top of the upper Campanian Black Creek Group and then in turn is overlain by Tertiary unconsolidated sands. The fossils that are usually there are missing their processes because of abrasion during the reworking of the material. During the upper Cretaceous this was a deltaic area where fresh, brackish and marine waters intermingled explaining the mixture of different species. Dinosaur carcasses apparently floated down the river and would be eaten, by the sharks, mosasaur and crocodiles, etc. This is a Hadrasaur Metatarsal bone. This location is one of the few dinosaur collecting locations in the SE. By the way this fossil is about 1 and a half inches across.

These are all crocodile teeth from the Phoebus Landing site on the Cape Fear River in NC. Apparently there were 3 species of croc. a relatively small one, a medium size one and the giant Deinosuchus which could be 35 feet long. Dinosaurs were a common prey for them. These are all from the Upper Campanian, Upper Cretaceous Black Creek Group about 78 ma.

I found those spherical, almost shapeless (or vaguely champignon-like) pieces in an SE Pyrenees Upper Campanian site with rudists, corals, ostreids and brachs. Could They be Siphonia sponges? A broken part of the last one

First described as Terebratella lujani by Luis Mariano Vidal in 1921. In 1984 Dr. Sebastian Calzada revised and created the new genus Ortholina: https://www.researchgate.net/publication/39118241_ORTHOLINA_n_gen_Brachiopoda_Cancellothryridacea_Cretacico_sup_Pirineos The genus was accepted in the Treatise in 2006.

Hello, I found those echinoids in Upper Campanian strata (SE Pyrenees) The first one I guessed to be an Orthopsis miliaris... But there is a problem. Orthopsis' apical disc is dicyclic, and in my specimen it is hemicyclic. I have numbered the plates as in The Echinoid Directory and the ocular plate "V" lies in contact with the periproct: Other options ? The second one is this small one. I guess Thylechinus, but according to TED this is a problematic genus. Apical disc seems dicyclic (madrepores are clearly visible in G2 plate)

From the album: Sponges, Kristianstad Basin
Upper Campanian, Cretaceous I thought this was a Callopegma aucale, but now am unsure. (See discussion below) I've used this ref for identification ->LINK I've concluded from other sources that the area where this sponge was found - does indeed belong to the (lower) Upper Campanian. About 16cm at the base and 17.5cm at the diagonal.
