HAGS

The purpose of the Harrisburg Area Geological Society (HAGS) is to stimulate geologic thought, advance and disseminate geologic knowledge, and provide fellowship amongst area individuals interested in earth sciences. Monthly meetings (at GTS Technologies at 441 Friendship Road in Harrisburg) present a realm of geologic topics, ranging from tectonics, coal, carbonate groundwater geochemistry, Martian geomorphology, engineering geophysics, nuclear waste repositories, and ore mineralogy. Field trips allowed members to visit geologic sites within and beyond Pennsylvania. All events are open to the public and free unless otherwise stated.

Up coming events :April 9, 2015, 6:30 p.m. Why is a Pteridinium like a desk? An overview and update on the Ediacaran Period” Presented by Dr. Mike Meyer, Penn State Harrisburg

HAGS_2015_4_9

Abstract:

“The Ediacaran Period (580–541 Ma) contains the first fossil evidence of complex organisms; however, the evolutionary relationship of these fossils to the animals of the Cambrian is still poorly understood and highly debated. This is because most Ediacaran fossils are unlike anything found since; some bear a superficial resemblance to various modern forms (such as sea pens, worms, or molluscs), whereas others appear completely alien (tri-patterned swirls, fractal folding patterns, and spindle shapes); leading some to suggest that these fossils represent an extinct branch of life. New analytical tools allow for an unprecedented view into the development of these enigmatic organisms and their ecosystem dynamics before the Cambrian Explosion.”

Bio:

Dr. Mike Meyer is a professor at Penn State Harrisburg, but has also done time at Bucknell and Western Carolina University. He got his BS from Beloit, an MS from University of South Florida, and his PhD from Virginia Tech. He has a lovely wife, several cats, and genetically modified fish that glow in the dark. He enjoys long walks on the beach, where he mostly looks down at the sand for freaky looking prehistoric critters that would send most beachgoers screaming for the hills. He likes to read by candle light, which can’t be good for his eyes. He has been to China to search for freaky prehistoric creatures, and his shenanigans are legendary near and far. Don’t challenge him to a hot wings eating contest.
