One of the most amazing fossil finds ever: during the Polish-Mongolian paleontological expedition to the Gobi Desert of Mongolia, in 1971, an articulated Velociraptor mongoliensis skeleton was found with hands and feet grasping a Protoceratops andrewsi. Evidence suggests that these two dinosaurs were indeed killed simultaneously, smothered by sand, possibly during a dune collapse.
The first specimen of Archelon Ischyros discovered. Collected in South Dakota by Dr. G.R. Wieland in 1895. Archelon ischyros is the largest sea turtle species documented with the largest find in 1975, measuring 16.5' (5.25m) wide across the carapace from the end of one front flipper to the end of the other outstretched front flipper. It lived in the Late Cretaceous (74 MYBP), a time when most of North America was covered by a shallow ocean.
