异常大型、根部完整的翼龙牙齿 - Coloborhynchinae 未鉴定 - 白垩纪 Kem Kem 层 - 牙齒化石 (沒有保留價)

Scientific name: Rooted Pterosaur tooth - Coloborhynchinae indet

Location: Taouz, South Morocco

Geological Formation: Ifezouane Fm - KemKem Red Sandstone Beds

Age: Upper Cretaceous, Cenomanian stage ( 96 million years)

Size: 6,5cm

REF.: #J629

DESCRIPTION:

Observations:

Stunning large and almost fully rooted tooth. It has some restorations along fractures it suffered during excavation. These restorations basically consist of filling the fractures. In this case, the root its fully authentic and not composite. The fractures have been glued and filled, but unlike other cases, the root its real. About restorations and filled fractures: This is a typical technique used by local excavators to restore teeth. It's not a professional technique, and it leaves much to be desired.

But, still, its a pretty unusual fully rooted amazing tooth.

About Moroccan Cretaceous Pterosaurs:

The teeth you can find in market should be labelled as Coloborhynchinae indet. based on the fact that Sirrocopteryx, and Coloborhynchus fluviferox are the only known Ornithicheiraens from Kem Kem, this was wrong. There are 5, or possibly 6 Taxa of Ornithocheiraen present in the Kem Kem Beds.

Let go into detail with 4:

Sirrocopteryx: Now Sirrocopteryx is an interesting case, there are claims of it being an Anhanguerid, but as of now, we cant confidently say this to be true, so we stay with the identification of it being a Coloborhynchine Ornithocheirid. Now, what Ornithocheirids have Teeth we can reference? Ferrodraco and Mythunga. We can see roughly triangular very robust teeth in Mythunga, or rather long conical teeth that are still very robust.

Coloborhynchus fluviferox: This is another Coloborhynchine from the Kem Kem Beds, it also is the largest Ornithocheiraen in Kem Kem, due to it's existence it's probably better to identify your Teeth of this Morphotype as Coloborhynchinae indet.

Anhangueridae: Wellnhofer and Buffetaut, 1999 describe a very interesting Pterosaur tooth, "The teeth of morphotype IV are very ro- bust, large and recurved. In cross-section the teeth are rounded lingually, but flattened labially. A carina is de- veloped only along the posterior edge. The enamel pat- tern varies, but, in general, appears to be similar to the pattern of the other morphotypes. The surface of the enamel is smooth. The flattened labial surface of the den- tine is slightly wrinkled. The rounded surface of the lingual side is sculptured by fine, parallel, longitudinal striae and wrinkles. The length of the teeth preserved ranges from 28 to 39 mm." Wellnhofer claims these Teeth could be tentatively reffered to Anhanguera, but Anhangueridae indet. is preffered.

Targaryendraconidae: In (Pêgas et al. 2019) the Taxon Targaryendraco got described, which formed the basis of a new pterosaur family, Targaryendraconidae, in the same paper they describe "[...] are several isolated teeth that are elongate, striated, slightly recurved and elliptical in cross-section; including specimens from the Kem-Kem Beds, Cenomanian of Morocco"
