5.9" Fossil Theropod (Spinosaurus?) Sacral Vertebra - Kem Kem Beds

 
 
 
 
This is a 5.9" wide, fossil sacral vertebra of a theropod (likely Spinosaurus) from the Kem Kem Beds of Morocco. The centrum half of the neural canal (vertebral foramen) remained preserved, however everything above the pedicles wasn't recovered. There are fractures throughout the centrum, many of which required crack repair and gap fill restoration in spots.

There are two large theropods known from the Kem Kem Beds, Spinosaurus and Carcharodontosaurus. Both have very similar anatomy at the bone level. There are some subtle differences but this bone lacks the markers needed to make a definitive distinction between these two giant theropods.

The Kem Kem Beds are 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.

A paper on this assemblage can be found at: Vertebrate assemblages from the early Late Cretaceous of southeastern Morocco: An overview
