賣家描述
Scientific name: Carcharodontosaurus saharicus, Depéret and Savornin 1925 - Dinosaur Premaxillary Tooth
Location: Taouz, South Morocco
Geological Formation: Ifezouane Fm - KemKem Red Sandstone Beds
Age: Upper Cretaceous, Cenomanian stage ( 96 million years)
Size: 5,3cm
REF.: #J1020
DESCRIPTION:
Premaxillary tooth. It has some glued and filled fractures. It preserve the serrations (carina) pretty well.
The teeth with strong and vivid fossilization colors such as red, orange and black come from small paleochannels composed by thin layers, in the intermediate and upper stratigraphic levels (Red Sandstone Beds), from the Ifezouane and Aoufous Formations (Kem Kem Basin, South of Morocco). The lithology of this body of sediment is characterized by the dominance of sandstones (also known as arenites) and fluvial gravel, of siliceous nature. Sometimes large concentrations of iron oxide are present, and then a small sample of that is usually present at the base of the tooth.
These mineralizations are responsible for the wide range of beautiful reddish color tones, slowly drawn during millions of years via fossil-diagenetic processes. The complicated sedimentarian architecture of the layers where most large vertebrates are found makes the excavation methodology a real challenge.
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. If you find that your certificate has not yet been updated, please contact us and we will update it immediately. Display box included.
