Description: Fossil Trilobite: Flexicalymene Ouzregui Age : Ordovician, Approx. 430 to 500 Millions of Year Location : Tazzarine des Aït-Atta, Tarhbalt, Morocco Approximate Size : 7.8 x 5.2 x 2.5 cm A fine example of an outstretched (enflated) trilobite This trilobite measures a maximum length of approx. 7.8 cmThis specimen was collected from a hard claylike concretion which was split to remove the trilobite. The trilobite was glued back together without restorationTrilobites were marine arthopods, from the group Trilobita, with more than 10 thousand species some growing to 2 metres.The group Trilobita appeared in the Cambrian Period (520 million years ago) until the end of the Permian Period (250 million years ago). The name Trilobita is derived from the three (tri-) lobed structure of the exoskeleton, which has a raised central lobe (or axis) and a pair of side lobes, called pleurae. The trilobite body is also divided lengthwise into three regions : a head or cephalon, a middle region (thorax) composed of several to many articulated segments, and a tail plate called a pygidium, which consists of fused segments.Arthropods are the most species-rich animal phylum living today, and have been the most diverse group of multicellular animals since the Early Cambrian. Their main subgroups are the crustaceans (like prawns and crabs), the chelicerates (including spiders, scorpions, and mites), and the wholly terrestrial groups Insecta and Myriapoda (the latter including millipedes and centipedes).Trilobites were hard-shelled creatures that lived hundreds of millions of years ago in the Earth's ancient seas. The name "Trilobite" refers to the three segments that make up their bodies.They are considered to be one of our planet's earliest complex life-forms and became extinct before dinosaurs even existed. After dinosaurs, trilobites are arguably the most sort after fossils amongst both scientists and fossil collectors, alike.We are happy to supply a Certificate of Authenticity on request with purchase.
