Bivalve Clam - Fossil Burr Approximate Weight of 1 piece:Mined from: Mahajanga, Madagascar Era: MesozoicGeological Age: 145 to 200 mya Description: Something about these clams gets me. The polish is great and they are so solid to hold. They have a really aesthetic appeal with all the lines going across, and its instantly obvious they are shells. When you hold them, the heavy weight makes you know its a stone right away. One of my favourites for fossil bivalves. Approximate Size of 1 piece: 35mm x 32mm x
