The temporary and permanent exhibits in the Texas Memorial Museum are created from holdings of more than 5 million specimens. They include dinosaurs and fossil animals, gems and minerals, as well as recent wildlife specimens. These specimens come from geological and paleontological fieldwork conducted by The University of Texas at Austin scientists, and also from public donations.
The mountain lion exhibit on the third floor was part of the 1936 University of Texas Centennial Exposition, which was a festival to commemorate the 100 year anniversary of Texas' Independence from Mexico. The exhibit was placed in the Texas Memorial Museum after construction was completed. Other exhibits change to highlight current research and new acquisitions. The Museum also hosts traveling exhibits on loan from other museums.
