These are gorgeous, agate replaced ammonite fossils which have been cut in half and polished to reveal all of the detail of the inner chambers. It's a real cool fossil that would make a great gift or could even be used to make jewelry. These ones range from 1 1/2 to 2" wide, and are .3 to .4" thick. The photos are some representative examples of what they look like.
The ammonites are Middle Cretaceous in age, or approximately 110 million years old and collected from the Mahajanga Province of Madagascar.

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.
