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.
Plioplatecarpus
"Plioplatecarpus" was first found in Europe by paleontologist Louis Dollo ("P. marshi"), in 1882. It was relatively incomplete, but more fossils would soon turn up. In North America, Edward Drinker Cope found another mosasaur in 1869, but had identified it as "Mosasaurus". It would later be reclassified as "Plioplatecarpus", as would Cope's "Liodon", in 1870. "Liodon" would be reclassified as "Platecarpus", and later as "Prognathodon". However, some have placed it in the genus "Plioplatecarpus".
