This appears to me to be the severed head of a reptile. It is slightly deformed post mortem. Scales or osteoderms are faintly visible in a few places. There is a branched structure on the underside that looks very much like a blood vessel. There are circular shapes at the end where the head was severed from the body, suggesting a spine and torn ends of major vessels. It was found in Deuel County, South Dakota, USA. The geology of the area is basically glacial deposits. No strata or matrix evidence is possible. It measures 60 mm x 30 mm x 35 mm and weighs 80 g. Is this a reptile head, or am I suffering from pareidolia?

I recently heard of the discovery of soft tissues in a tyrannosaurus rex femur. That was a few years ago, but I was asking myself if I could try it out myself. Has somebody already tried this, or knows hown to do it? Thanks, Ramon G.
