Research Interests

In 1993, I received my bachelor's degree in geological sciences from the University of San Juan, in Argentina. In December 1996 I defended my Ph.D. thesis on the taphonomy and stratigraphy of the Ischigualasto Formation, the anatomical description of Saurosuchus galilei, and the phylogeny of rauisuchids. Upon completion of my graduate work, I moved to The University of Texas at Austin in May of 1997 to conduct postdoctoral research with Dr. Tim Rowe. Together we have CT- scanned several archosaur specimens from the Ischigualasto Formation.

I participated in numerous fieldwork expeditions, primarily in the Triassic Ischigualasto Basin. I also participated in the exploration of Upper Cretaceous sediments in south Mendoza and Lower Jurassic in the north of San Juan, both in Argentina. In 1998, I was part of the crew of Tim Rowe's expedition (UT Austin) to the Lower Jurassic Kayenta Formation in the Navajo Nation, Arizona.

In 1998, I was hired as Collections Manager for the Vertebrate Paleontology Laboratory of the Texas Memorial Museum at UT Austin. I also was instrumental in the completion and mounting of a cast of the pterosaur, Quetzalcoatlus northropi, in the Great Hall of the Texas Memorial Museum.

In April of 2000 I returned to San Juan. I am in charge of the Division of Paleontology of the Natural Sciences Museum. My research interests lie in basal crurotarsal archosaur and archosauriforms. I am also interested in the alluvial architecture and taphonomy of terrestrial environments. I also want to contribute to the knowledge of the biostratigraphy of the Triassic, trying to obtain additional data on paleomagnetostratigraphy and radiometric dating from fossiliferous sequences in Argentina and Brazil. I will be working this year in the Lower Jurassic Río del Colorado Formation (May 2000) and in the Upper Triassic Ischigualasto and Los Colorados Formations (September-October 2000).
