Fossil shark tooth and fish tooth in matrix, Late Cretaceous, K-Pg boundary

Description

For sale is a limestone matrix specimen containing one fossil shark tooth (Serratolamna serrata) and one
Enchodus
fossil fish tooth naturally exposed in matrix. The opposing surface contains several rounded phosphate pebbles. This specimen was collected from the Cretaceous-Paleogene boundary in central Arkansas and the fossil teeth are uniquely exposed on the bedding plane. Fossil teeth, such as those here, were concentrated along with invertebrate fossils in an ancient shallow marine environment. The specimen and exposed teeth are sturdy and only a minor amount of glue was applied to stabilize the shark tooth.
A very unique specimen
dating back to the Cretaceous-Paleogene boundary and mass extinction event associated with the extinction of the dinosaurs and marine reptiles. A great addition to any collection!!
