Scientific name: Nigersaurus taqueti, (Sereno et al., 1999) - Rebbachisaurid sauropod dinosaur tooth Location: Gadoufaoua, Téneré Desert, Niger. Geological Formation: Erlhaz Fm Age: Lower Cretaceous, Aptian/Albian stage ( 113 million years) Size: 2cm REF.: #S594 DESCRIPTION: Here we introduce this exceedingly rare dinosaur tooth from Elrhaz Fm. It is an authentic tooth of Nigersaurus, herbivorous sauropod rebbachisaurid dinosaur that lived during the Aptian stage of the Early Cretaceous of modern-day Niger. Small for a sauropod, Nigersaurus was about 9 m (30 ft) long, and had a short neck. It weighed around 4 t (4.4 short tons), comparable to a modern elephant. Observations: Very nice specimen with nicely developed feeding wear. Not restored or glued. Elrhaz Formation is mostly made up of fluvial sandstones. A diverse assemblage of fossil animals has been recovered, bony fish, turtles, several genera of crocodylomorphs (Anatosuchus, Araripesuchus, Sarcosuchus, and Stolokrosuchus), undescribed ornithocheirid pterosaurs, the theropod dinosaurs Eocarcharia, Kryptops, Suchomimus, and an undescribed noasaurid (possibly Bahariasaurus), the sauropods Nigersaurus and an undescribed titanosaurian (Malawisaurus), and the iguanodontians Lurdusaurus and Ouranosaurus. All of our fossils come with a Certificate of Authenticity. Every week, the issued Certificates of Authenticity are updated in our database verification system on our website.
