Like just about all mosasaur mounts, it is extremely difficult to capture the specimen in one photograph without losing much of the detail. The museum store does sell a very well done poster featuring this specimen. The museum also houses many other vertebrate and invertebrate fossil specimens, as well as an extensive mineral collection.
Admission is free .
The museum also offers several field paleontology courses for credit during the Spring and Summer months. This web page will, of course, feature the mosasaur material on display as well as some pictures of mosasaur specimens not seen by the public. So kick off your shoes and get ready to enjoy a virtual journey into the late Cretaceous seas that once covered South Dakota, and the rest of the Midwest. This skull is about 4 feet long, from the nose to the back of the lower jaw. The left side of the same skull.
