Aspidorhynchus sp. Garfish scales collected from Florida, USA. These particular scales date back to the Miocene Epoch, approximately 23 - 5 Mya. Garfish are prehistoric fish which are still alive today, they have occupied North American waters since the cretaceous and have remained very much unchanged during that time. They have an air bladder which acts as a primitive lung, this enables them to exploit murky, poorly oxygenated, swamps, rivers and backwaters. These scales naturally range in size between 2 and 3 cm long, they are sold individually and are supplied in a small plastic bag with an information label.
