One skull discovered around 1780 was famously nicknamed the "great animal of Maastricht".
The Mosasaurus hoffmannii skull found in Maastricht between 1770 and 1774. The first publicized discovery of a partial fossil mosasaur skull in 1764 by quarry workers in a subterranean gallery of a limestone quarry in Mount Saint Peter, near the Dutch city of Maastricht, preceded any major dinosaur fossil discoveries, but remained little known.
Mosasaurs are the largest-known squamates. The largest-known mosasaur is likely Mosasaurus hoffmanni, estimated at more than 17 m (56 ft) in length, [260] [261] however these estimations are based on heads and total body length ratio 1:10, which is unlikely for Mosasaurus, and probably that ratio is about 1:7. [262]
Some mosasaurs measured just a few feet long, while the largest — in the genus Mosasaurus — was nearly 60 feet (18.2 meters) long, and while mosasaur fossils are relatively plentiful ...
