15.4" Polished Ammonite Fossil - Amazing Specimen!
This is a gorgeous, and absolutely massive, 15.4" wide polished ammonite fossil. It is Late Cretaceous in age and was collected in the Mahajanga Province of Madagascar. It's of the genus Lytoceras which is one of the more uncommon ammonites from the locality.
The exterior of this ammonite has been highly polished, revealing the "suture" patterns of the shell and areas of gorgeous red/green iridescence. There is an impression of another, smaller ammonite near the "mouth" of the shell.
It makes an amazing display on the included metal display stand. And did we mention it's huge!?!

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.
