This week's fossil is a specimen of Asterophyllites equisetiformis. A. equisetiformis is an extinct form of horsetail, related to Annularia. This particular fossil was found by Jim Konecny in the 1960's. Jim was president of ESCONI in 1966. He was a prolific fossil collector and has two Mazon Creek species named for him and his wife Sylvia. Flashback Friday #30 was an article on Mazon Creek by both of them.
