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.
Amphitherium
The first jaws of mammals from the Mesozoic - including "Amphitherium" - were found in the Stonesfield Slate, part of the Forest Marble Formation at Kirtlington Quarry in England . These were bought by a student of William Buckland's. Although he thought the jaws were mammalian, he asked the great anatomist Georges Cuvier for his opinion. He misidentified them as being from a marsupial mammal, "Didelphis". Later they were identified as being a new genus, and named "Amphitherium". It was first mentioned in the scientific literature alongside "Megalosaurus", by the famous British paleontologist Reverend William Buckland. It came from the Stonesfield Slate of Oxfordshire, England, and Buckland described it in 1824 as ""not less extraordinary"" than the dinosaur, but it was the larger fossil reptile that captured public imagination.
