Geology Class Unearths Fossil at Lake Ouachita
Hot Springs, Arkansas – Students in Dr. George Maxey’s Geology class participated in a field trip in October. The class discovered graptolite fossils in the Womble formation west of Checkerboard Point on Lake Ouachita. Maxey explained that the graptolites were preserved as a carbon imprint at the bottom of the Tethys Sea, which no longer exists. “Plate tectonics closed the ancient sea and scraped the sediments off the bottom of the sea floor and folded the sediments up and onto what is present day Arkansas - forming the Ouachita Mountains. The upper folds eroded away leaving the roots of the mountains that are exposed at present,” said Maxey.
