Prognathodon Giganteus Mosasaurus Jaw 690mm originating from the Phosphate deposits of Benguerir, Oulad Abdoun Basin, in Morocco. Dating back to the Maastrichtian age, Cretaceous age. Restored free of its surrounding matrix prepared in our lab from the fossil layers of the Cretaceous age. The origin of this fossil partial skull was the classic Phosphate deposits of the oulad abdoun basin, Ben Guerir, Morocco. A scientifically important specimen for what was once a formidable marine predator and a fine museum specimen.
Sympathetic conservation has been carried out in the cleaning process of the teeth and bone tissue of this Prognathodon giganteus mosasaur. Some of the original teeth have been re-seated where necessary. Verso the specimen is completely free of matrix, exposing alveoli sockets and root placement and an associated bone attachment. The surface of the bone tissue has been consolidated. Air abrasive has been kept to minimal use, so as not to disturb the tissue. Mostly the specimen has been patiently cleaned under a large lens. All the teeth are authentically associated with the jaw, no attempt has been made to over-restore the specimen with fillers etc.
Originating from the Phosphate deposits of Benguerir, Oulad Abdoun Basin, in Morocco. Dating to the Turonian to Maastrichtian ages, approximately 93 to 66 million years, in the Cretaceous era 135 to 65 million years. The Mosasaur was featured in the latest saga; Jurassic world. The Prognathodon Giganteus Mosasaurus was the king of our prehistoric oceans. At the pinnacle of the food chain and probably one of the most perfected apex marine predators known to Earth. First discovered in the 18th century in Maastricht near the river Meuse.
The Mosasaurs with the extinction of the ichthyosaurs and pliosaurs became the dominant marine predators of the age.
The Cretaceous period marine reptile featured in the saga of Jurassic world films. The Mosasaurs were a group of perfectly developed marine predators, resembling a crocodilian and lizard form, huge double-hinged jaws and skulls armed with many teeth; It is thought they could unhinge their jaws and gulp down large prey. Powerful flippers and streamlined bodies. At first, it was thought that Mosasaurs used their bodies like snakes or eels when swimming, in an undulating side to side movement. However, the most recent research nows leads us to theorise their bodies remained stiff and a large fluked tail provided the locomotion which propelled the Mosasaur.
Part of a more ancient group of aquatic lizards, the aigialosaurs group. Mosasaurs breathed air, gave birth to live young and grew from around 3 feet; Dallasaurus turneri, the smallest Mosasaur to 50 feet in length; Mosasaurus hoffmannii, the largest. The Mosasaurs reigned for around 20 million years before the mass extinction which also ended the dinosaurs' existence, around 65 million years ago at the K-T boundary event. This was the last 20 million years of the Cretaceous period. The Turonian to Maastrichtian ages.
The first fossils were discovered in an 18th-century limestone quarry near Maastricht on the river Meuse. When first discovered the skeleton was thought to be that of a dragon and the major of Maastricht had the fossil bones put on display in a glass case for all to marvel at the size of the amazing new discovery.
