that Helicoprion is one crazy animal with a very interesting history! 3 years of research and we are still learning something new about them all the time. It is interesting that for as little is known about them there are over 60 publications about the genus. For your reading pleasure I present a story of research, madness, forced labor camps, and execution. All in the pursuit of this enigmatic shark! http://www.g-to-g.co...ilter=repressed

Good afternoon, I would like to start off with saying that I know very little about fossils and Geology so please excuse me if I make any errors or misstatements. Recently I purchased approximately 10 cubic yards of rock from a local business to use for landscaping around my property. The business has claimed that the rocks they sold me were excavated from in or near the banks of the Snake River in Southern Idaho.

The picture is the fossil as is, the guy that collected it POURED shellac over the entire surface The blue tinted 3d model is what I built today based on a surface scan of the ro

The Tucson Fossil Shows 2012: One Collector's Report
siteseer posted a topic in General Fossil Discussion
The various gem-mineral-fossil shows that are collectively known as "The Tucson Show" ended last Sunday. Many people consider the official end to be the close of the main show at the convention center but many dealers are long gone by then at the other shows. I've been going to the Tucson shows since 1989 with some missed years in the early 2000's. I've seen established shows disappear or change venue with even the names of the venues changing two or three times. The town had seemed to deteriorate over time, but this year, Tucson looked a little clear - perhaps because construction on the
