Minerals/Fossils - Trilobite

<b>Trilobite Paladin (Kaskia) bedici</b>Trilobites are a group of extinct arthropods. Their body was segmented into the cephalon (head), segmented thorax (body), and pygidium (tail). Their back was covered with a hard three-part chitinous skeleton divided into the head, thoracic and tail shield. The trilobites bore a long central axis, or axial lobe, flanked on each side by the lateral lobe. The exoskeleton (external skeleton) was divided lengthwise into three prominent lobes, the medially located axial lobe and two lateral pleural lobes (on each side of the body). <br>Trilobites were in the Palaeozoic Era one of the most important and the most numerous animal species. The oldest specimens appeared in the Early Cambrian Epoch, about 520 million years ago and last ones died out at the end of the Palaeozoic Era about 250 million years ago.<br>The trilobite species Paladin (Kaskia) bedici depicted on the stamp lived together with two other trilobite species and two subspecies on the territory of today's Spodnje Počivale in the Late Carboniferous Epoch, a little more than 290 million years ago and represented the most important Carboniferous trilobite fauna in the Karavanke. Spodnje Počivale in Javorniški Rovt is a very rich collecting area of Late Carboniferous fossils where several samples of the new trilobite species were found, among them the whole exoskeleton. The species was described by Prof. Gerhard Hahn and Renata Hahn from the Marburg University . At Anton Ramovš's suggestion, the species was named bedici in honour of the Jesenice-native Jože Bedič, who contributed a great deal to the very rich trilobite collection from the Jesenice area.<p>Anton Ramovš<br>
