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.
Mustelidae
The oldest fossil of the mustelids were dated at the end of the Oligocene to the beginning of the Miocene. “There is debate regarding which fossils from these epochs represent possible ancestral forms that led to Mustelidae and which fossils represent the first modern mustelids.”(Wund, M. 2005. "Mustelidae" (On-line), Animal Diversity Web.) From the fossil record we can see that Mustelids appeared in the late Oligocene period (33 mya) in Eurasia and migrated throughout the continents. The Mustelids inhabit every continent except Antarctica and Australia. The mustelids migrated all throughout the continents that were connected during the early Miocene. The Mustelids made their way to North and South America via the Bering land bridge.
