Large, 1.59" Fossil Pterosaur (Siroccopteryx) Tooth - Morocco

This is a 1.59" long, fossil Pterosaur (Siroccopteryx) tooth from the Kem Kem Basin, Taouz, Morocco.


Siroccopteryx moroccensis is a Late Cretaceous pterosaur whose fossils are found in Morocco. It would have been one of the largest pterosaurs with a wingspan of around 12-15 feet (4-5 meters). This animal was likely a specialized glider, and ventured into the sea off the coast of Africa to capture fishes and other prey that swam near the surface.

The exact genus and taxonomy of this pterosaur is still up for debate. Some researchers consider it a member of the Coloborhynchus genus, some consider Siroccopteryx a separate genus, and others have proposed that it is closer to the Anhanguera genus. Siroccopteryx appears to be the most widely used genus name.

Siroccopteryx had a unique dental pattern. The front two teeth were flattened and stuck straight out of the front of the jaw. The next three sets of teeth were curved and stuck out to the side of the jaw. The last two pairs of teeth stuck straight out of the jaw. This arrangement was probably to help the Pterosaur to catch the fish it fed on.

The Kem Kem Group is famous for yielding a diverse Late Cretaceous vertebrate assemblage, including fish, reptiles, and dinosaurs such as Spinosaurus. These fossils are found in a thin bed that outcrops around the edge of a large plateau near Taouz, Morocco. Local miners collect these fossils by digging narrow tunnels by hand into this plateau, following the layer.
