Here a Mosasaurus hoffmanni just misses the mark in an attack on the marine crocodile, Thoracosaurus, in the seas over present day New Jersey. Wanna bet on the outcome? These Maastrichtian age animals are known from both North America and the Netherlands in Europe (the North Atlantic was much smaller 68 million years ago).  Thoracosaurus survived for some time after the K/T boundary event while mosasaurs, plesiosaurs, dinosaurs and many other groups did not. Although first found in the Netherlands, M. hoffmanni is also known from the Western Interior Sea (Texas).
