This Fossil Trilobite comes from Utah. It is 32 mm (1 1/4") tall (46 mm, 1 3/4' including bail). It is wrapped in my clay, put on a cord and is ready to wear. Trilobites are one of the oldest invertebrates known. They first appeared in the Early Cambrian era (540 mya) which is the first age in the Paleozoic era and they died out 248 mya in the Late Permian, which is the last age in the Paleozoic era. Their hay day was from the Late Cambrian through the Ordovician, the second age in the Paleozoic). Trilobites are arthropods and are distantly related to crabs and lobsters. Their body is made up of three sections, the head (cephalon), body (throax) and tail (pygidum). The body has segments and each segment has a pair of legs. Some trilobites could role up their body like a pill bug (sow bug, rolly polly). Some swam, all crawled and some burrowed. Some had compound eyes, some had their eyes on long stalks, while others lacked eyes altogether. Their bodies can be smooth, rough, or spiny. They ranged in size from a less than ½ an inch to more than 2 feet. They are known to have lived in all the different ocean environments, the majority of them were scavengers feeding on plankton digging through the sediment looking for organic food, only a few were predators. As they grew they molted their shell like modern crustaceans. Paypal accepted, foreign buyers please contact us before purchasing for shipping information
