LIMA — A talk called “Biosphere Collapse and Recovery: Lessons from the Fossil Record” will begin at 3 p.m. Friday, Nov. 16 in Science 115 at OSU-Lima.
Professor William Ausich, professor emeritus in the school of earth sciences, will speak on how major mass extinctions today compare to those in the past.
3 p.m., Fri., Nov. 16, 2018, Science 115
Professor William Ausich presents Biosphere Collapse and Recovery – Lessons from the Fossil Record. Program description: Earth is in the midst of a biodiversity crisis with extinctions occurring at an alarmingly high rate. However, this is not unique, as major mass extinctions have occurred through the evolutionary history of life on earth. One avenue of research to address the present-day crisis is to study ancient extinctions and faunal recoveries to help understand their causes and to help reduce the severity of biodiversity crises. The causes of ancient mass extinctions and recoveries are explored using the fossil record of the Crinoidea (sea lilies and feather stars, phylum Echinodermata), marine organisms that dominated ocean floor communities during much of earth history. Ausich is a professor emeritus in the School of Earth Sciences. His presentation is sponsored by the Honors Program and the Department of Earth Sciences.
