Clam Fossil from Madagascar is about 150 million years old, dating from the Jurassic Period. Clams have a long fossil history, first appearing in the late Cambrian Period, about 510 million years ago. Clams are bivalve mollusks, so-called because their shells consist of two parts called valves. The valves are attached by a hinge ligament and are opened and closed by two muscles attached to the inside of the shells. Clams are filter feeders that pump water inside their bodies to strain out phytoplankton and other small organisms for food.
Please be aware of the nature of fossils:
Being buried under the ground for millions of years under tons of pressure tends to be rough. No fossil comes out of the ground whole and perfect. Most fossils have undergone some restoration, while others are altered by man simply to enhance their presentation in different ways. The workers in Madagascar do a very professional job, unearthing and preserving these natural treasures, however, commonly natural cracks are visible on the surface. These are part of the natural beauty of the fossil and not considered defects.
