.82" Unusual Sauropod Dinosaur (Nigersaurus?) Tooth - Morocco
This is a .82" long tooth of a Moroccan diplodocid sauropod, likely either Nigersaurus sp. or Rebbachisaurus garasbae. It comes from the Late Cretaceous Kem Kem beds of Morocco, home to such meat eating giants as Spinosaurus and Carcharodontosaurus.
Comes with an acrylic display case.

About These Unusual Sauropod Teeth
They're possibly the rarest type of sauropod teeth out of the Kem Kem beds, with a beveled edge on both sides of the tip. The teeth are typically under an inch, though have been found to be slightly larger. Most of their characteristics are consistent with those of Rebbachisaurus teeth, but the extra beveled edge resembles Nigersaurus teeth. The Kem Kem beds have a stratigraphic range of ~100 - 95 million years ago, indicating there could have been a relatively brief period where both genera lived amongst each other.
About Rebbachisaurus
Rebbachisaurus is a genus of sauropod dinosaur of the superfamily Diplodocoidea that lived during the Early-Late Cretaceous period in Africa about 99 million years ago. It reached lengths of up to 20 meters (65 feet) long. This massive four-legged plant-eating animal had a small head, a long, graceful neck, and a whip-like tail. Rebbachisaurus is distinguished from other sauropods by its unusually tall, ridged back. The discovery of Rayososaurus, a South American sauropod nearly identical to Rebbachisaurus, supports the theory that there was still a land connection between Africa and South America during the Early Cretaceous, long after it was commonly thought that the two continents had separated.

About Nigersaurus
Nigersaurus is a genus of rebbachisaurid diplodocoid the lived during the middle Cretaceous period, about 119 to 99 million years ago. This sauropod is known for its flat front jaws lined with three rows of over 100 small sharp teeth, giving it a shape similar to that of a flat nozzle on a vacuum cleaner. It had a relatively short neck, thin skull bones, and habitually held its head down to the ground, implying that it worked like a vacuum cleaner, the mouth methodically moving from one side to the other as it clipped its way through ferns and other low foliage. Nigersaurus specimens have been collected in north-western Africa where during its time, the region was damp and swampy.

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.
