Today, we have a beautiful, huge Gilpichthys greenei. G. greenei was named for Frank Greene, who was a long time Mazon Creek collector. Frank is also the namesake for Reticulomedusa greenei. He owned a small rock shop in Coal City during the heyday of Mazon Creek collecting. You can learn more about G. greenei in Mazon Monday #140.
This breathtakingly detailed specimen comes from Bob Masek. A former fossil preparator at the Field Museum and the University of Chicago, Bob is known as one of the best fossil preparators in the Chicago area and one of the few who works on Mazon Creek fossils. Thanks for sharing, Bob!
