Jeff Martz, Ph.D. Student

Bachelor of Science (Zoology), 1999, Colorado State University, Fort Collins, CO.

Master of Science (Geosciences), 2002, Texas Tech University, Lubbock, TX.

Ph.D. student, Dept. of Geosciences, 2002 - present, Texas Tech University, Lubbock, TX.


"My primary research interest is Late Triassic vertebrate paleontology in the American Southwest, especially vertebrates from the Dockum Group of western Texas.  I have been working mainly on aetosaurs (stagonolepidids), which were heavily armored pseudosuchian (or "crurotarsan") archosaurs that were common during the Late Triassic.  My Master's thesis redescribed the material of the aetosaur Typothorax from the Post Quarry of western Texas and the Canjilon Quarry of north-central New Mexico.  I am currently collaborating on aetosaur related projects with Bryan Small of the Denver Museum of Nature and Science, Bill Mueller of the Texas Tech Museum, and Bill Parker of Petrified Forest National Park.  My doctoral focuses on lithostratigraphy, chemostratigraphy, and vertebrate biostratigraphy of the Dockum Group.  My other interests in vertebrate paleontology include mosasaurs (giant Cretaceous marine lizards)."
