Petrified Forest— Paleontologist and geologist Dr. Jeffrey Martz will be providing a presentation titled “Reconstructing time: using rocks and fossils to uncover the beginning of the Age of Dinosaurs” as part of the park’s Science and Education Center Lecture Series. This presentation will focus on current research to determine the order of rock layers in the park and the timing of the first appearances of specific species of fossil reptiles in the rock record. The presentation will begin at 10:00 a.m. on Wednesday, August 6, 2008, and will be held at the Painted Desert Visitor Center Community Building in Petrified Forest National Park.
