4.7" "Glowing" Fossil Ammonite (Asteroceras) - Dorset, England
This is a beautifully preserved 4.7" wide ammonite (Asteroceras obtusum) fossil from the Lyme Regis region of England. The ammonite was naturally replaced with calcite which fluoresces white-yellow under short-wave UV light. The rock has been completely removed from each side, allowing for the ammonite's translucence to show when backlit. A photo of the backlit ammonite can be seen above.

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.
