BELEMNITE & BIVALVE FOSSILS

Fossilized Belemnite Rostrums and Fossilized Bivalve Clam Shells

The Belemnite Rostrum Fossil from Mahajanga, Madagascar, is a remnant of an extinct marine Cephalopod, known for its bullet-shaped, Calcite structure that formed part of its internal skeleton. Originating from the Jurassic to Cretaceous periods 66 - 200 million years ago, these fossils showcase a smooth or faintly striated surface, with concentric growth rings revealing a lifespan of about four years.

Bivalve Fossil Clams from Tulear, Madagascar, dating back to the Late Jurassic Period, approximately 160 million years ago. These exquisitely preserved fossils, part of the Trigonia family, showcase the distinct, hinged shells of Bivalve Mollusks with intricate textures and a range of colors.
