Found in a formation famous for its dinosaurs, supposed to be 110 million years old (Middle Cretaceous).
Some argued that it could not be a fossilized finger since pressure from overlying layers mashes fossils flat. This is usually true, but not in the Glen Rose Formation. Several locations reveal thousands of fossilized worms that are perfectly three dimensional. If anything should be mashed flat it would be worms, but they are not. Obviously, very rapid lithification is required in order to preserve such astonishing detail.

The fossil has been replaced with limestone. Sometimes replaced fossils maintain their interior structure. Sometimes they do not. Fortunately, when the fossil was sectioned, we were able to see obvious indications of bone and ligaments.

Medical Doctor Dale Peterson of Oklahoma City, OK examined the sectioned specimen by means of x-ray, CT Scan and MRI. He was able to identify joints and to trace tendons throughout the length of the fossil. His expert conclusion is: "There can be no reasonable doubt that this is a fossil finger." continue
