Mount Saint Peter
Around 1765 the skull of a "Mosasaurus" was discovered here in a limestone quarry, one of the first recognised reptile fossils, which was later acquired by the Teylers Museum in Haarlem. A more famous "Mosasaurus" fossil was found between 1770 and 1774 but was confiscated by the French in 1794 and is now in the Muséum national d'Histoire naturelle in Paris. Later dinosaur remains were discovered here as well, belonging to "Betasuchus" and "Orthomerus", as well as turtles and fossils of smaller creatures of the sea.
Aetosaur
Aetosaur fossils have been found on all continents except Australia and Antarctica, giving them a nearly worldwide distribution during the Late Triassic. Many aetosaur remains have been found from the Chinle Group in the southwestern United States. Most fossils have been found from Arizona, New Mexico, and Texas. Some remains have also been found from Utah, particularly in Canyonlands National Park and Zion National Park. Aetosaurs are also known from the Newark Supergroup along the East Coast of the United States in states such as Connecticut and North Carolina. Two genera are known from Greenland: "Aetosaurus" and "Paratypothorax". They have been found from the Fleming Fjord Formation in Jameson Land. "Longosuchus" is the only aetosaur known from Africa, with scutes having been found from the late Carnian Timesgadiouine Formation in Morocco. During the Late Triassic, Morocco would have been in close proximity with the Newark Supergroup of North America in the supercontinent of Pangaea. It is also possible that "Desmatosuchus" was present in Africa, as fossils have been found from the Zarzaitine Series in Algeria that were referred to the genus.
