These wonderful line drawings were made of a very complete, three-dimensional skull of Mosasaurus missouriensis (KUVP 1034) in the collection of the Museum of Natural History at the University of Kansas. Originally described by S. W. Williston as a new species (M. horridus), Russell (1967) and others consider it to be another example of M. missouriensis, first described by Harlan (1834) and Goldfuss (1845). Additional photographs of this specimen are found on the Mosasaurus and Other Mosasaurs Virtual Museum webpage.
