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.
Invertebrate paleontologists in the Jackson School focus on the development of early Paleozoic echinoderms. This includes trying to determine the origin, early evolutionary history, paleoecology and closest relatives of the earliest crinoids in the Early Ordovician based on new collections from the Rocky Mountains. Researchers are also looking at the expansion of all types of echinoderms during the Cambrian Explosion and the Great Ordovician Biodiversification Event.
There is also interest among the School’s invertebrate paleontologists in relationships between organisms over time, especially within reef environments. Rudists, a type of extinct bivalve important in reef environments, are a particular focus of interest. Researchers explore the connections between changes in major reef-building organisms through time to better understand how conditions in the global ocean changed. Because they provide a unique long term perspective, the University’s extensive fossil collections are used by researchers to relate ancient to modern climate changes.

PhD Student Graduate
I am accepting applications for a new PhD Student in my lab. This student must be interested in paleontological or carbonate sedimentology research (both would be best), and should be aware of the current/recent projects in the Martindale Lab. Exceptional MSc students will be considered, but preference is for a doctoral student (prior research experience at the undergraduate or MSc level is desired).

NPL, part of the Texas Natural Science Center, 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.
There are several aspects to our laboratory that make it different from others. One is our automatic handler system created at California Institute of Technology and adapted for our needs. Scientists and students can keep up with changes to our system by keeping in touch with the other 6 similar systems in the world and RAPID Consortium at http://rapid.gps.caltech.edu/. It also includes a cryogenic magnetometer and portable magnetic susceptibility meter (TerraPlus KT-10 Plus).
Skeleton Preparation Facility
Located at the VPL Annex on the Pickle Research Campus, the Skeleton Preparation Facility is used to transform fleshy carcasses of modern animals such as birds, mammals and reptiles into clean skeletons for comparison with paleontological specimens.
The Vertebrate Paleontology Laboratory (VPL) is known worldwide as a major repository for unique scientific collections from the American Southwest. VPL was founded in 1948 by John A. Wilson, Emeritus Professor of Geology at The University of Texas at Austin. Today, VPL is the principal repository for vertebrate fossils collected from state and federal lands in Texas and contiguous areas, as well as for specimens collected elsewhere using state and federal funds. The fossil vertebrate holdings of VPL rank among the seven largest in North America.
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.
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.

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.
