July 20 Program Review

Past Climate: Putting the Puzzle Together

Angela Kline-Osen, PhD discussed how scientists use geology, paleontology, biology, and models to help determine possible climatic conditions of the past. Her focus was on Texas, particularly the DFW region, but she also expands a bit about the Permian-Triassic period (about 250 million years ago) as that is where much of her research has been concentrated.

Dr. Osen is a Professor at Tarrant County College where she regularly teaches Earth Science and Oceanography. She has also served as Field Camp Coordinator for Geology Field Camp and taught Earth Systems as well as Historical Geology at the University of Texas at Arlington. She received her PhD in Earth and Environmental Science and from the University of Texas at Arlington where her research concentration was on Paleoclimate and Paleoceanography. She also has her Bachelor of Science in Geology through UTA. During the summer, she assists with fossil prep at the Heard Museum. Previously, she had volunteered as a dig crew member at the Arlington Archosaur Site. Dr. Osen’s discussion of the processes and results of that dig got a lot of questions (and answers).  To see the photos and hear the discussion, you can view the recorded Zoom program.

A couple of reference tips from Dr. Osen – a wonderful interactive map of Texas geology – https://txpub.usgs.gov/txgeology/ and a free smartphone app Dr. Osen recommended – Rockd from the University of Wisconsin-Madison.
