There are no repairs or restorations to this piece. The limestone is extremely hard and difficult to prepare, so this material is rarely seen on the market.

Ammonites

Ammonites are an extinct group of marine mollusks that belonged to the class Cephalopoda, closely related to modern squids, octopuses, and nautiluses. They lived from the Devonian period (about 400 million years ago) until their extinction at the end of the Cretaceous (around 66 million years ago). Ammonites are characterized by their coiled, chambered shells, which were divided by intricate suture patterns. These creatures were free-swimming predators or scavengers in ancient oceans, using their tentacles to capture prey. Their widespread distribution and rapid evolution make them important index fossils, helping scientists date and correlate rock layers worldwide.

Prida formation

Ammonites from the Prida Formation in Nevada are fossilized marine mollusks from the Late Triassic period, roughly 200 million years ago. The Prida Formation, located in east-central Nevada, consists primarily of limestone and shale, indicative of deposition in a shallow marine environment.
