Mookaite, also known as Mookaite Jasper, is a silicified porcellanite mineral that can also be fossiliferous (containing fossils within). Its original vein was found in Western Australia in outcroppings near the Mooka Creek. It is said to have formed during the Cretaceous Period (145-66 million years ago). This area is full of tiny nanoplankton fossils such as Radiolaria and Foraminifera, both of which played a huge role in the creation process of Mookaite. This Mookaite is relatively recent discovery from Morocco where conditions were just eighth to create this type of jasper!
