Fossil Study Group
August 17, 2016 meeting
Today we were treated to an excellent Training Session on Corals by Loretta Bailey, who has been a long-time ammonite and baculite fossil collector on Spud Hill, north of Central & Orchard in Cañon City. The site was a former Tepee Butte before the hill was leveled by a land developer many years ago. (“Tepee Buttes are carbonate mounds formed around methane springs and vents on the seafloor of the Cretaceous Interior Seaway.” S. Veatch)
Loretta described the 3 types of corals: Rugosa, Tabulata and Scleractinia. She explained that they are relatives of today’s jellyfish. We studied the anatomical structure of corals, the environment they live in, coral reef formation, extinction periods and growth rings. Under magnification, daily coral growth lines are visible!
