🌍 About Spinosaurus
Spinosaurus aegyptiacus was a large theropod dinosaur from the mid-Cretaceous of North Africa, around 100 million years ago. Its fossils are known above all from the Kem Kem Group of southeastern Morocco, a series of ancient river deposits. Its long snout carried straight, conical teeth suited to catching slippery prey such as fish, and it is regarded as one of the longest carnivorous dinosaurs known.

Where it comes from
Moroccan Origin
The Kem Kem beds of south-eastern Morocco are river and delta deposits from the Cenomanian, the first stage of the Late Cretaceous, roughly 100 million years ago.
They preserve an unusual ecosystem dominated by large predators, including Spinosaurus and Carcharodontosaurus, alongside pterosaurs, crocodile relatives and giant fish.
Reported locality for this specimen: Kem Kem Beds, NW Sahara Desert, Morocco.

From the rock
Discovery
In the Kem Kem, fossils are usually found as isolated teeth and bones. Ancient rivers scattered remains before burial, which is why complete skeletons are exceptionally rare.
Large predatory dinosaurs shed and replaced teeth throughout their lives, so their hard, enamel-covered teeth are the fossils most often recovered.
