Report on the Arlington Archosaur Site to be presented at GSA meeting

March 13, 2009

Boulder, CO, USA - The 43rd annual meeting of the Geological Society of America's South-Central Section will feature a presentation on Tuesday, 17 March, on the Arlington Archosaur Site in North Arlington, Texas, USA. Among the site's 95 million-years-old rocks is a rich deposit of fossils, not only of an as-yet-unnamed carnivorous theropod, but also of a large, herbivorous "duck billed" hadrosaur, prehistoric crocodiles, turtles, sharks, and a new species of lungfish. Details are posted at presenter Derek Main's Web site,

Archosaur is Greek for "ruling reptiles" and represents a group of reptiles that includes dinosaurs, pterosaurs, and relatives of the modern crocodile. To date, more fossils have been recovered from the Arlington Archosaur Site than from any other site in the Dallas-Fort Worth Metroplex.

The South-Central meeting will take place on the Richardson, Texas, campus of the University of Texas at Dallas. Main's presentation will take place on Tuesday, 17 March at 3:00 p.m., in room 1.102 of the University of Texas at Dallas Conference Center.
