Spinosaurus Aegyptiacus Dinosaur Tooth 120mm


Availability:In stock


Spinosaurus aegyptiacus tooth 120mm long. A fine specimen tooth the dark mahogany colour of the fossilised dentin-enamel is excellent, the time has been kind and the fossil preservation could not be better. The angled wear to the tip of the crown is life wear, the morphology of habitat and feeding while the tooth was still rooted in the dinosaur's jaws! The stout tooth is very stable, the enamel condition excellent, completely unrestored. This is a naturally collected Spinosaurus aegypticus conical tooth, from a semi-aquatic theropod sailed back top predator which once stalked the margins and lagoons of the Cretaceous period in search of large fish and sharks.

Spinosaurus aegyptiacus tooth 120mm. Excellent preservation of the dinosaur tooth, exhibiting mahogany colour dentin-enamel and a typical patina of the red bed's fossil site. The curved tooth is a very good type specimen having the large root attached. Spinosaur teeth from this fossil deposit often demonstrate red or maroon tones this from a heavy content of iron in the fossil red bed formation when the dinosaur skeleton or teeth were deposited in the Cretaceous period. The completeness and robust nature of the tooth is interesting morphologically, the tip of the crown appears to have life ware, while the tooth was in the dinosaur's jaws, making the Spinosaur aegypticus dinosaur tooth scientifically important.

Spinosaurus was a semi-aquatic predator, along with the margins of lagoons and it has been theorised a free swimmer. The many sawfishes in the fossil deposit at Kem Kem suggests this was one of the main sources of food for Spinosaurus. We often find the teeth and bones of Spinosaurus alongside the rostral teeth of the Onchopristis numidus sawfish, up to 23 feet in length! And hybodus sharks, up to 7 feet in length. Palaeontologists also have suggested the large sail which may have been a multicoloured warning of size to other Spinosaurs when hunting and semi-submerged when swimming. Here is a opportunity to gain a rare and fine grade fossilised dinosaur tooth of the ferocious and renowned theropod predator, longer than Tyrannosaurus rex, with slender but powerful snapping crocodile gharial type elongated jaws, ornamental ribbed dorsal sail and huge conical peg ripping teeth which terrorised the cretaceous waterways, which today have evolved into the Sahara desert region between Morocco and Algeria.

Spinosaurus and Tyrannosaurus Rex did not co-exists during the Cretaceous period, Spinosaurus is found in fossil layers of the Kem Kem beds dating between 112 to 97 million years ago, whereas tyrannosaurus is found on the North American continents between 72 to 66 million years ago, the two great continents separated around 180 million years ago.

There are various influences affecting fossil dinosaur teeth and their recovery, the extraction process plays a role in the overall outcome of fossils generally, particularly the dinosaur teeth of North Africa. Dinosaur fossils and the diminishing resource they are, in this region of the world and in this unique deposition, near complete teeth are limited in the fossil record. It requires much time in the field at the fossil bed digging long trenches and underground pits and tunnels to acquire fossil teeth and dinosaur bones and often not of good quality or of good preservation, many are lost when the excavations are carried out by commercially minded fossil diggers who are often pressured to extract fossils in an area of military and political unrest.
