Fossil preparation is a complex of tasks that can include excavating, revealing, conserving, and replicating the ancient remains and traces of organisms. It is an integral part of the science of paleontology, of museum exhibition, and the preservation of fossils held in the public trust.
The salt lick, or lick, as it is more generally known locally, and its fossil deposits, were long known to the original inhabitants of the area. [12] [13] The area was named after the extraordinarily large bones, including those of mammoths and mastodons, found in the swamps around the salt lick frequented by animals, who need salt in their ...
The Chagrin Shale is found in north-central and northeastern Ohio, and in northwestern Pennsylvania. [7] The Chagrin Shale reaches a maximum thickness of 1,200 feet (370 m) in eastern Ohio. [7] In Ohio, the Chagrin Shale is thin in the west, [2] [3] and thickens as it proceeds east. [7] The Chagrin Shale also extends south into West Virginia. [9]

In geology, petrifaction or petrification (from Ancient Greek πέτρα (pétra) ' rock, stone ') is the process by which organic material becomes a fossil through the replacement of the original material and the filling of the original pore spaces with minerals.
Scientists have revealed fossils of a giant salamanderlike beast with sharp fangs that ruled waters before the first dinosaurs arrived. The predator, which was larger than a person, likely used ...
These three-dimensional fossils create permanent molds of internal structures. The mineralization process helps prevent tissue compaction, distorting organs' actual size. A permineralized fossil will also reveal much about an organism's environment and the substances found in it since it preserves soft body parts.
