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.
Ghost Ranch
200 million years ago Ghost Ranch and the American Southwest were located close to the equator, and had a warm, monsoon-like climate with heavy seasonal precipitation. Ghost Ranch includes a famous palaeontological site preserving Triassic dinosaurs. Fossil bones were found here as early as 1885. In 1947 the palaeontologist Edwin H. Colbert documented the discovery of over a thousand well-preserved fossilized skeletons of a small Triassic dinosaur called "Coelophysis" in a quarry here. In 2007, fossil remains of "Dromomeron romeri", one of the archaic group of animals recognized as basal dinosauromorphs, were found in the Hayden Quarry. In April 2010, a team of scientists led by Hans-Dieter Sues of the Smithsonian Institution reported the discovery of "Daemonosaurus chauliodus", a basal theropod species, at Ghost Ranch. "Daemonosaurus" lived approximately 205 million years ago, during a transitional period between the oldest known dinosaurs such as "Herrerasaurus", which existed during the Late Triassic period in what is now known as Argentina and Brazil, and the more advanced theropod dinosaurs.
