Indy Posted September 18, 2011 Share Posted September 18, 2011 Conostichus (a fossil with a confusing history) was formerly thought to be a jellyfish resting trace. It is now regarded as a burrow infilling or feeding structure of an unidentified organism.

jkfoam Posted September 18, 2011 Share Posted September 18, 2011 Barry is right. This was initially thought to be a scyphozoa (Jellyfish) and some paleo people will still argue for jellyfish. It was initially identified and described in the literature as Duodecimedusina typica (King, 1953). I'm not positive about that 1953 date. I believe the Treatise of Invertebrate Paleontology for Coelenterata lists the species as Inserta Sedis meaning they are not sure how or where to classify it. Still it is a rare specimen. If you count the lobes on your specimen you will come up with twelve. I have found two, one of which is shown below. Mine was found in the Texas Pennsylvanian near Fife, Texas.
