No: 2029400008438The species has distribution on all horizon Size: plate 68x27cm; trilobite approx. 14cm(weight 17 kg) Rare species of ordovician Asaphidae trilobites from St.Petersburg regionOriginal safety of fossils - clustered trilobites shell only one species together. It has not reconstruction of matrix - the position of trilobites is original! The shell of trilobites has little reconstruction nearly 5%.This species was found in Volkhov River outcrop. ABOUT TRILOBITES Trilobites ("three-lobes") are extinct marine arthropods that form the class Trilobita. They appeared in the Early Cambrian period and flourished throughout the lower Paleozoic era before beginning a drawn-out decline to extinction when, during the Late Devonian extinction, all trilobite orders, with the sole exception of Proetida, died out. The last of the trilobites disappeared in the mass extinction at the end of the Permian about 250 million years ago (m.y.a.). Trilobites are very well-known, and possibly the second-most famous fossil group, after the dinosaurs. When trilobites appear in the fossil record of the Lower Cambrian they were already highly diverse and geographically dispersed. Because of their diversity and an easily fossilized exoskeleton, they left an extensive fossil record with some 17,000 known species spanning Paleozoic time. Trilobites have been important in biostratigraphy, paleontology, and plate tectonics research. Russian Ordovician trilobites are very well-known collectible fossils.These trilobites are all absolutely of the highest quality. Exacting care has gone into the prep work on each and every one of these. I am sure you will agree once you see them up close and personal. They are all lower Ordovician, approximately 500 million years old...yes, a half a billion years old! PAYMENT We accept PayPal and bank translation.
