  • Ogyginus sp. pygidium £3.00£5.00 ex VAT

    Ogyginus sp fossil pygidiums from the Llanvirn series during the middle of the Ordovician period, the samples come from mid Wales in the UK and are preserved on a fine grained solid mudstone matrix. The pygidiums (tail) are available and it is believed that this is due to moulting behaviour of the animal in which it anchored its tail to the sea floor to moult its old carapace, during the process. The samples are well preserved and range between 15 t0 20 mm in size and increasingly more difficult to come by. They are ideal for both collectors and enthusiasts but also ideal for educational use to describe the animals behaviour in life, each samples will come supplied in a white card tray with an information label.
