Lot: 10 Lbs Polished Ammonites (2.5 to 3") - 38 Pieces

This is a wholesale lot of 10 lbs of beautiful, polished ammonite fossils from Madagascar. These ammonites are Late Cretaceous in age or approximately 110 million years old.

There are 38 ammonites in total ranging from 2.5" to 3.1" wide with most being closer to 3". They have all been polished and some have some iridescent shell preservation, while the sutures underneath the shell can be seen on others.

At $150 for the lot, that is just over $3 per ammonite fossil.

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.
