About the Society Awards Past Award Winners 2011 (Lanzendorf PaleoArt Prize) Jeffrey W. Martz
As a high school student, I first became involved in paleontology as an intern at the Denver Museum of Natural History working under Ken Carpenter and Bryan Small. I studied zoology and geology at Colorado State University, getting my bachelor’s degree in 1999. At the Department of Geosciences at Texas Tech University, I specialized in Upper Triassic continental stratigraphy and vertebrate paleontology under Sankar Chatterjee and Tom Lehman, and I received my master’s and doctoral degrees in 2002 and 2008. My work at Texas Tech, and subsequently at Petrified Forest National Park (where I worked from 2008-2011), has focused on the morphology and systematics of aetosaurs (heavily armored pseudosuchian archosaurs) and on producing detailed and accurate lithostratigraphic and biostratigraphic models for the Dockum Group and Chinle Formation in Texas, Utah, Colorado, and Arizona.

I did not have much time to pursue art after high school, but began producing scientific illustrations as an undergraduate at Colorado State University and as a graduate student at Texas Tech University. I produced botanical, vertebrate and invertebrate illustrations for biologists at those institutions, but my work has since focused on vertebrate paleontology, primarily for my own research projects. Although I have mostly worked with pen and ink and colored pencil in the past, I have moved almost completely into electronic artwork. I do both my technical illustrations and life restorations using Adobe® Photoshop® and a BambooTM drawing tablet.  Most of my technical drawings are of skeletal elements, most of which are black and white line drawings filled in with stippling, but my Revueltosaurus illustration is a shaded drawing using the airbrush and eraser tool.

Revueltosaurus callenderi is a small pseudosuchian archosaur known from the Upper Triassic (Norian-Rhaetian) Chinle Formation of the western United States.  The taxon was first known exclusively from its dentition, which was so similar to that of early ornithischians dinosaurs that it was originally identified as such.  However, in 2004 a locality was discovered in the Painted Desert of Petrified Forest National Park which included both cranial and postcranial remains of several individuals, clarifying the phylogenetic affinities of Revueltosaurus as a pseudosuchian allied to aetosaurs. The reconstruction is based primarily on PEFO 34561, the most complete specimen of the taxon known, which includes an almost complete disarticulated skull and much of the rest of the skeleton. Being one of my first experiments doing shaded technical drawings in Photoshop®, it took quite a bit longer than expected.
