NEW GEOLOGY EXHIBITS AT UT KNOXVILLE'S McCLUNG MUSEUM
The Frank H. McClung Museum at the UT Knoxville
campus recently unveiled a new permanent gallery "Geology and the
Fossil History of Tennessee" and a temporary exhibit featuring the
Burgess Shale - on loan from the Smithsonian through December 1. Admission
to the museum is free; museum hours are 9-5, Monday-Saturday, 1-5 Sunday.
The remainder - and largest part - of the gallery is devoted to the geologic periods represented by surface deposits across Tennessee. The Cambrian, Ordovician, Silurian, Devonian, Mississippian, Pennsylvanian, and Cretaceous are each represented by important fossil specimens accompanying a life-size diorama, explanatory text, a paleocontinental reconstruction, and a map showing locations of rocks across the state. Marine dioramas typically are based on particular rock formations - Cambrian is based on the Nolichucky Shale, Silurian is based on the Brownsport Formation, and the Cretaceous is based on the Coon Creek Formation. The large Pennsylvanian diorama portrays a coal swamp forest setting, with lycopods, seed ferns, large insects, and an amphibian.
The center of the gallery focuses on vertebrate life of the Mesozoic, including the five hadrosaur bones, which remain the only dinosaur bones reported from Tennessee. High quality casts of a hadrosaur skull (Edmontosaurus) and a theropod skull (Albertosaurus - which has been found in the southeast) are augmented by real specimens of ornithopod and theropod eggs from China. A large, complete, hadrosaur tibia from the western US is available for visitors, who would like to touch a real dinosaur bone. Hovering overhead and leering downward toward the gallery entrance is a complete mosasaur skeleton cast.
Cenozoic fossils are not neglected. There is an exhibit of Claiborne Formation leaves and seeds from the famous clay pits at Puryear, Tennessee. Next is an exhibit of Miocene/Pliocene vertebrate remains from the famous "Gray Site" near Johnson City, featuring bones and teeth of tapirs, rhinoceras, gomphothere elephants, turtles, alligators, and a turkey. A painted mural of the sink hole - lake, one of the interpretations of the Gray Site environment, accompanies the specimens. Finally, a case containing Pleistocene specimens includes mastodon, dire wolf, jaguar, caribou plus porcupine, bulfrog, and a land snail. Paleovegetational analysis of pollen grains by Hazel and Paul Delcourt rounds out the depiction of the last 20,000 years of Tennessee's fossil history. UT geology professor Tom Broadhead is curator for the permanent gallery exhibits.
