I've had a number of questions raised via PMs and posts on Dinosaur claws from the Kem Kem Beds so here is a topic on that subject. We know very little about their morphology and that is not unexpected because this region continues to mystify everyone and new discoveries are constantly changing our understanding of these dinosaurs. Spinosaurid foot claws are the best understood but since we really do not know how many species exist, currently two, its difficult to assign the morphology shown below to any specific one. Best described as Spinosaurid indet. Note the dimple on the ventral surface The claw shown below is generally accepted as a Spinosaurid hand claw but like the foot claw cannot assign it to a specific species. Not aware of any publication showing this morphology in the Kem Kem but very similar to claws in other regions. Best described as Spinossurid indet. Abelsaurid foot claws..multiple species may exists do there may be some variation to this design Best described as Abelsaurid indet. Foot Claw of a Carcharodontosaurid. No Kem Kem claws have been described so like Spinosaurids hand claws we look at other regikns to compare agsinst. Tyrannotitan is a Carcharodontosaurid from Argentina Again there are multiple species described so best described as Carcharodontosaurid indet.
