The lot contains a diverse selection of teeth, dental fragments and other remains representing several groups that inhabited the river systems and surrounding environments of the Kem Kem ecosystem. The assemblage includes: Several indeterminate fish fossil fragments and fish teeth Crocodyliform tooth Spinosaurid teeth and tooth fragments Squalicorax shark tooth Fossil ray dental element 2 Otodus teeth 2 shark teeth attributed to Sand Tiger 1 tooth attributed to Odontaspis 3 Onchopristis rostral denticles 2 fragments of Onchopristis rostral denticles 1 fossil vertebral element, attributed to the same Kem Kem fish assemblage Additional small fossil fragments visible in the photographs Particularly interesting are the remains of Onchopristis, the large extinct sclerorhynchid ray characteristic of the Kem Kem fauna, together with teeth representing predatory fishes, sharks, crocodyliforms and spinosaurids. The collection provides a good overview of the remarkable diversity of vertebrates that occupied the ancient river systems of northern Africa during the Cenomanian. All specimens are offered together as one lot. Some pieces are fragmentary, as expected for naturally preserved material from this locality. Please examine the photographs carefully, as they form an important part of the description. Origin: Kem Kem Beds, southeastern Morocco Period: Late Cretaceous – Cenomanian Age: approximately 100–94 million years Condition: Natural fossil specimens, with varying degrees of preservation and fragmentation.
