Nebraska Turtle Fossil Restoration - ~Fini!


Texas Fossil Hound

Recommended Posts

After 2 months of prep and restoration, I have finished the Nebraska Turtle from the Oligocene. Unfortunately, it is missing some of the carapace rim along the back of the shell, but after going from a compressed pile of shell to this, I am very happy with the outcome.

Outstanding result! What adhesive did you use?

To stabilize the fossil when I pulled it out of the cliff I soaked it pretty well in a solution of Elmers Glue and water. When I unwrapped it, I soaked it in water which disolved the Elmers glue solution. I take the fossil in sections and clean them one at a time taking time to glue each tiny piece back together as they break off. I am using cyanoacrylate (Superglue) as my main adhesive, but am looking for alternatives that do not yellow the fossil. Its not bad, but I don't like it when you can see it.

That's really nice work. You can fill in the cracks and restore the edges with 2-part epoxy putty and then texture and paint it to match the fossils.

There are illustrations showing the top and bottom of the Oligocene turtle, Stylemys nebrascensis, on page 155 of "After the Dinosaurs: The Age of Mammals" by Donald Prothero (2006). I assume that's the same turtle you have. The illustrations are reprinted from Joseph Leidy's 1854 work on mammals and turtles from the badlands of Nebraska.

I have a similar project - field prepped Oligocene turtle but it is coated in superglue. A friend was going to get to it eventually but he passed away last year and his widow asked me if I would fix it up for her. I need to finish cleaning the outer surfaces, reset a couple of pieces, and then fill in the missing shell with putty. Some matrix was removed from the front interior. The collector must have been digging into it to see if any bones were present

That is a really beautiful turtle. You certainly were able to piece it back together splendidly! Thanks for updating us!

Texas Fossil Hound, Thanks for you comment revealing your prep approach. It was just what I wanted to know. Congrats again on a great piece.

Thanks all! The Rhino is in progress!

At the end of November I am picking up my new COMCO suite in LA from a Lawyer that got it and then let it sit until his wife made him sell it. Score!!!
