15" Massive, White Ammonite Fossil (68 Lbs) - Madagascar
This is a massive, 15" wide ammonite fossil from the Upper Cretaceous of Madagascar. This doesn't appear to be one of the more frequently seen types and is 9" thick, weighing over 68 lbs. It has a white shell with some areas of natural iridescence. There is a large, fossil snail which was fossilized inside of it and is exposed at the end. This giant, display piece displays well just leaning up against a wall or other hard surface.
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.
