6.1" Calcite-Replaced Ammonite (Aegasteroceras) Cluster - England
This is an absolutely beautiful ammonite fossil cluster from the Conesby Quarry near Scunthorpe in North Lincolnshire, England. It's Lower Jurassic in age, or approximately 200 million years old. The ammonites are of the species Aegasteroceras sagittarium and the largest measures 3.4" wide. The shells of the ammonites were naturally replaced by calcite. A fossil oyster can be found exposed from the rock along the edge of the specimen. The base of the rock has been cut flat for aesthetic presentation of the ammonites without the need for a display stand.
There is some restoration to the bottom ammonite, located in the 2 - 3 o'clock area.

About Ammonites
Ammonites were ancient marine cephalopods, similar to today's squids and octopuses, but with a defining feature: their distinctive, tightly coiled spiral shells. These shells, resembling those of modern nautiluses, served as both a protective home and a buoyancy aid, allowing ammonites to navigate the prehistoric seas with ease. First emerging around 240 million years ago in the Triassic Period, ammonites thrived for over 175 million years, adapting through numerous forms and sizes. As predatory creatures, they likely fed on smaller marine organisms, using their tentacles to capture prey. However, their long reign came to an end 65 million years ago at the close of the Cretaceous, coinciding with the mass extinction event that also eliminated the dinosaurs.
