Glen Canyon Lecture Series Presents “Fifteen Years of Paleontology”
By Dr. Barry Albright
Friday September 19 | 7:00 p.m. at Carl Hayden Visitor Center, Glen Canyon Dam
This event is the keynote address for the Big Water Dinosaur Festival !
Since 1999, personnel from Glen Canyon National Recreation Area, Grand Staircase-Escalante National Monument, the Museum of Northern Arizona, the Utah Museum of Natural History, the Utah Geological Survey, and the University of North Florida have been involved in a robust and detailed survey of the vertebrate paleontology preserved in Upper Cretaceous strata of the Kaiparowits Plateau region of southern Utah. Research over these years has confirmed that these fossil-rich layers preserve one of the best records in the world of Late Cretaceous (approximately 95 – 75million years ago) life. One of the geologic units in this thick sequence of strata preserves a remarkable record of ancient marine life that lived and died in a vast inland seaway that ran across North America from the Gulf of Mexico in the south to the Arctic Ocean in the north, quite literally bisecting the continent into eastern and western halves about 93 million years ago. Over the last 15 years, research on this unit, known as the Tropic Shale, has greatly expanded our understanding of the organisms that called this seaway home.
