SAMPLE ISSUE The Monongahela Rockhound News is a Monthly Publication of the Monongahela Rockhounds, Pittsburgh, Pennsylvania Sample Issue November 2014 Visit us on the Web at: www.monongahelarockhounds.org A Pittsburgh Area Mineral, Fossil, & Lapidary Club Tiny, Ancient Crustacean Preserved in Fool’s Gold An international team of geologists, led by University of Leicester Emeritus Professor of Palaeontology David Siveter, captured a prehistoric portrait of parental care deep in the fossil record. The team revealed a ‘sea nursery’ which features a species of ostracod new to science, Luprisca incubi. Ostracods are a class of crustacean sometimes known as “seed shrimp,” because of the shrimp-like body sandwiched between a bi-valved shell that hinges on their back. Today, ostracods are abundant wherever water is found, but they are still virtually unknown to humans due to their small size. Some 70,000 species of ostracod have been identified, and ancient ostracods are thought to have lived alongside trilobites in poorly oxygenated waters. According to the team, these fossils are the only known invertebrate fossils that seem to indicate simultaneous brooding of eggs, embryos, and young. The fossils also indicate that this habit, maintained by some ostracods today, has persisted for at least 450 million years. Most living ostracods lay their eggs outside their bodies, but a few living groups still brood their embryos inside. The number and size of L. incuba‘s brood is similar to its modern descendants. This find not only highlights ostracods’ remarkable reproductive and brood-care strategy, but it is now the oldest confirmed occurrence of ostracods in the fossil record. The new fossils are truly spectacular in that they are exceptionally well preserved in iron sulfide, or pyrite – also known as fool’s gold – conserving not only the shell but, in this case, a few other tiny, stunning details of anatomy that are almost always lost in the fossil record, including antennae, legs, gills, and muscles! Underside of pyritized ostracod, from Siveter, et al in Current Biology These pyritized ostracods came from rocks of the Upper Ordovician Katian Stage Lorraine Group of New York State, including examples from the famous Beecher’s Trilobite Bed in Oneida County. The discovery extends human knowledge of the paleobiology of ostracods by some 25 million years. - Ron Smart Volume 47, Issue 9 Monongahela Rockhound News Page 2 General Information Monongahela Rockhounds PO Box 18063 Pittsburgh, PA 15236 www.monongahelarockhounds.org Mission Statement To promote, among its members and the general public, an interest in collection of minerals, fossils, and associated items. ● To promote their use in lapidary work. ● To promote the study and classification of minerals, gem stones and other items of such nature.
