Semi-Aquatic Lizard

Spinosaurus Aegyptiacus Dinosaur Tooth 120mm

£692.00 GBP

Spinosaurus aegyptiacus tooth measuring 120mm, this specimen is in 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 are 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 suggest 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 Spinosaurus 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-exist 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.
