Dactylioceras commune ammonite fossil – jurassic impression grade d – yorkshire, uk – 100% genuine with certificate

Description

This listing offers a genuine fossil impression of Dactylioceras commune, one of the most iconic ammonite species from the Jurassic period, found along the ancient coastline beds of Yorkshire, England. These specimens date back to approximately 180 million years ago, when marine life flourished in the warm shallow seas covering much of Britain.

Unlike three-dimensional body fossils, these specimens are mostly negative impressions, where the external form of the ammonite is preserved in fine-grained matrix. Despite being flattened, these impressions still capture the fine ribbing and iconic spiral structure that makes ammonites one of the most recognisable and collectable fossils.

Dactylioceras commune was a small to medium-sized ammonite, part of the subclass Ammonoidea, and belonged to the class Cephalopoda—relatives of today’s squid and octopuses. Their shells were coiled and ribbed, providing both protection and buoyancy. They were free-swimming marine predators or scavengers.

Geological Context: These fossils come from the Lower Jurassic (Toarcian) rocks of Yorkshire, particularly from coastal sites such as Whitby, where fossils are exceptionally well preserved. The area is famous for its fossil heritage and is a key part of the UK’s Jurassic Coast.
