The Jackson School’s paleontology program is distinguished by its diverse and active faculty, modern equipment, and extensive reference collection. It has perennially been considered one of the top paleontology programs in the nation.

Paleontological research at the Jackson School is motivated by several overarching questions: What were the causes and mechanisms for change in major lineages represented in the fossil record? What is the evolutionary history of lineages such as echinoderms, reptiles, and mammals? How can we use the fossil record and phylogenetic hypotheses to test current theories, and make predictions about potential consequences of current global-change phenomena?

Vertebrate paleontologists in the Jackson School focus on the evolutionary morphology of vertebrates, evolutionary ecology (recent and ancient), phylogenetic systematics, and the evolution of development. A major tool in this work is a high resolution computer-aided tomography scanner for 3D imaging of fossil vertebrates.

Center for Planetary Systems Habitability

The Center for Planetary Systems Habitability is an interdisciplinary research center at UT and is the result of a partnership between the Jackson School, the College of Natural Sciences, and the Cockrell School of Engineering. The center advances our ability to search for life on other planets by collaborating on research that helps better understand where habitable zones develop and how they evolve within planetary systems.

High-Resolution X-ray Computed Tomography Facility

The High-Resolution X-ray Computed Tomography Facility at The University of Texas at Austin (UTCT) is a national shared multi-user facility supported by the Instrumentation and Facilities Program of NSF's Earth Sciences (EAR) directorate. UTCT offers scientific researchers across the earth, biological and engineering sciences access to a completely nondestructive technique for visualizing features in the interior of opaque solid objects, and for obtaining digital information on their 3D geometries and properties.

Non-vertebrate Paleontology Laboratory

NPL was created in 1999 as an answer to the increasing conservation and curation issues developing with the huge increase in collection size. Collections placed in the care of TNSC mainly were derived from research at the BEG, the UTDGS and the Museum (TMM) itself. Other material came from orphaned collections within Texas. Numerous other collections have been contributed as donations. Although an exact count has never been made, the collection is estimated to contain about 4 million specimens.

Vertebrate Paleontology Laboratory

The mission of the Vertebrate Paleontology Laboratory is three-fold, involving research, conservation, and education pertaining to the history of vertebrates. In particular, VPL focuses on the history of vertebrates in Texas and adjacent regions, but much broader studies are also conducted to establish a national and global context for Texas vertebrate history.
