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 Group
The Kem Kem Group, also known as the Kem Kem Beds, is a significant geological formation located in southeastern Morocco, specifically in the region of the Anti-Atlas Mountains. This formation dates back to the late Cretaceous period, approximately 95 million years ago. The Kem Kem Beds are primarily composed of sandstone, siltstone, and claystone, interspersed with various sedimentary features that indicate a fluvial to deltaic environment.
The Kem Kem Group is renowned for its rich fossil deposits, which include a diverse array of prehistoric fauna. It has yielded a wide variety of dinosaur fossils, including theropods like Spinosaurus and Carcharodontosaurus, as well as large Sauropod dinosaurs such as Rebbachisaurus. Additionally, the beds are home to many other fossilized creatures, including crocodiles, pterosaurs, fish, and a range of invertebrates.
Paleontologists consider the Kem Kem Group an important site for studying late Cretaceous ecosystems and the evolution of vertebrate life. The fossils found in this region have provided valuable insights into the diversity and behavior of prehistoric species, making it a key location for both scientific research and fossil collecting. The striking landscapes of the Kem Kem Beds, with their colorful rock formations and dramatic geological features, also attract geologists and tourists interested in the natural history of the area.
