Hey everyone You guys might already know about this, but since this fossil is so wonderful, I decided I'd share this paper on TFF (it's kind of old news, but it's a really fascinating find). The paper describes a xenacanth shark (Triodus sessilis) with two temnospondyl tetrapods (Cheliderpeton latirostre and Archegosaurus decheni) as gut content. One of those temnospondyls had ingested an acanthodian fish (Acanthodes bronni) which is also preserved in the fossil. Basically, a "fish in an amphibian in a shark". The specimen was collected from the Permian of Lebach (southwestern Ger

I've finally got around to compiling some photos of my tetrapod footprints from a road cut here in Maryland. All of these finds come from the early Mississippian aged Purslane Formation, which belongs to the Pocono Group and thus are about 350 million years old. In Maryland the Purslane represents the late Tournaisian through the Visean stages of the Mississippian. These finds are particularly interesting because they come from an era known as Romer's Gap, which was a span of time from the end of the Devonian to the end of the Mississippian where worldwide fossils of tetrapods are rare, and k

a book review of: "Earth Before the Dinosaurs" written by Sebastien Steyer; illustrated by Alain Beneteau; translated by Chris Spence. Indiana University Press. 182 pages. Suggested retail: $35.00 USD. In the past twenty years a number of fossil discoveries have illuminated several steps of a key transition in the history of vertebrates: when they first crawled out of water and took on the gravity of life on land. Paleontologists have been sorting through the remains of a growing diversity of Devonian-age fish-like amphibians and amphibian-like fishes across a time when biologists have gone b
