Rastellum oyster bivalve (fossil Alien)
Age: Cretaceous
Location: Marovoay, Mahajanga district, Madagascar

More commonly known as ‘Fossil Alien’s these amazing bivalves are actually oyster shells.  Bivalves are bilaterally symmetrical molluscs having two calcareous, asymmetrical shells (valves) – they include the clams, oysters, and scallops. In most bivalves, the two shells are mirror images of each other (the major exception is the oysters). They occur in marine, estuarine, and freshwater environments.

ACTUAL AS SEENThe image shows the EXACT specimen you will receive. The specimen has been carefully hand selected and photographed. Measurements are as accurate as possible, though be aware measuring precise dimensions can be difficult from irregular shaped items. Whilst we portray colours as close to life-like as we can, colours will vary if taken in sunlight, indoors, from monitor to monitor and device to device. Once this specimen is sold, we will update this listing with new similar selected item, with a new photo and dimensions so this listing will change after you purchase. The scale cube in the photo is 1cm to give a visual size.
