Description

Details

Cypridea spinigera ostracod remains on shale matrix collected from the Cretaceous Wealden Shales of Yaverland, Isle of Wight. The Wealden deposits of the Isle of Wight are predominantly fluvial, they contain marls, sandstones, shales and even limestones. They are well recognised among palaeontologists because of the dinosaur remains which they yield however they do contain other terrestrial fossils such as fresh waster bivalves, insects and in this case Cypridea spinigera; a fresh water ostracod. The remains are small < 1 mm however they are very abundant within the shale matrix. The shale pieces vary in size but average sized pieces measure approximately 4 x 3 cm in dimension. Supplied in a small plastic bag with an information label.
