Showcasing the museum’s most valuable specimens, the Great Hall exhibits many specimens never before seen by the public. The highlight of this hall is Quetzalcoatalus northropi, the Texas Pterosaur, a flying reptile unearthed in West Texas by The University of Texas at Austin scientists. With a wingspan of 40 feet, Quetzalcoatalus northropi is the largest flying creature ever found. The exhibit entitled Natural Wonders: Treasures of the Texas Memorial Museum draws directly from the research conducted by university scientists. Specimens are rotated periodically into exhibit from the collections several times during the year, allowing visitors to see a greater diversity of specimens.
