Specimen: Opalised Complete Bivalve
Age: Lower Cretaceous
Location Found: Lightning Ridge, New South Wales, Australia

Opal forms in cavities within rocks. If the cavity is there because part of a living thing – for example a bone, shell or pinecone – was buried in the sand or clay before it turned to stone, then the opal can form a fossil replica of the object that was buried.

The sediments that buried plant and remains in the opal fields were rich in silica from ancient volcanoes, so here we have fossils preserved as silica in the form of opal.

ACTUAL AS SEENThe image shows the EXACT unique specimen you will receive. 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.
