As the ancient super-continent Gondwana broke up in the mid-Jurassic period, Madagascar was wrenched from eastern Africa. The mini-continent thus formed included present day Madagascar and India existing until about 88 million years ago when India split off and began drifting to a collision with Asia. Madagascar remained in place, a chunk of ancient Gondwana preserved to the present day.The ammonite fossils we offer lived in the warm shallows of a Jurassic and Cretaceous sea that lapped the western shores of that long lost island continent.  Here are beautiful fossilized examples of Upper Cretaceous ammonites presently coming from Madirovalo and Jurassic ammonites from Tulear, Madagascar.All the ammonites we offer from Madagascar have been polished or otherwise altered from their "as found" state.  The reason is simple, Madagascar law makes it illegal to export un processed fossils.  We assume this is a worthy measure to provide jobs for the Malagasay from the island's natural resources.
