2005-01 R&C Newsletter
Research & Collections News The Occasional Newsletter of the Research and Collections Staff Natural History Museum of Los Angeles County re•search (rī-sûrch′, rē′sûrch) n. 1. Scholarly or scientific investigation or inquiry. See synonyms at inquiry. 2. Close, careful study. 3. When performed on collections, the raison d’être of all great natural history museums. January, 2005 (covering the months of November and December, 2004) Collection News Mineral Sciences Several very fine mineral and gem specimens were donated to the Museum at the end of 2004 by two long-time supporters, greatly enriching the Gem and Mineral Collection. Mel Hindin donated three sapphire crystals from Sri Lanka, a rubellite tourmaline crystal from Brazil and a bi-color tourmaline crystal and a pink tourmaline gem from California. Most notable are the two tourmaline crystals. The 15-cm-tall rubellite is from one of the world’s most famous tourmaline discoveries, which occurred in 1978 at the Jonas mine in Minas Gerais, Brazil. The 19-cm-tall green/pink bi- color crystal is from one of California’s most famous tourmaline discoveries, which occurred in 2001 and 2002 at the Cryo-Genie mine near Warner Springs in San Diego County. All of the specimens donated by Mel Hindin are already on display in the Hall of Gems and Minerals. At left: Rubellite Tourmaline – Jonas mine, Minas Gerais, Brazil At right: Bi-color Tourmaline – Cryo-Genie mine, San Diego County, California Beverly Savinar donated three exceptional mineral specimens from the collection she and her late husband Hyman built. Perhaps, the most striking is 16-cm-tall crystallized gold on quartz from the Eagle’s Nest mine in Placer County, California. -

Other authors corroborated this family as a natural group among caviomorphs and recognized some taxa recorded from the Deseadan–Colhuehuapian South American Land Mammals Ages (SALMAs). Among them, Banderomys leanzai (the only species of this ge- nus) was, until now, characteristic and exclusive of the locality of Cerro Bandera (early Miocene, Colhuehuapian?, Neuquén Province, Argentina). The aim of this work is to report the first record of B. leanzai outside the type locality; the new specimens come from the early Miocene of central Chubut Province (Patagonia, Argentina). -
Major Radiations in the Evolution of Caviid Rodents: Reconciling Fossils, Ghost Lineages, and Relaxed Molecular Clocks
Major Radiations in the Evolution of Caviid Rodents: Reconciling Fossils, Ghost Lineages, and Relaxed Molecular Clocks Marı´a Encarnacio´ nPe´rez*, Diego Pol* CONICET, Museo Paleontolo´gico Egidio Feruglio, Trelew, Chubut Province, Argentina Abstract Background: Caviidae is a diverse group of caviomorph rodents that is broadly distributed in South America and is divided into three highly divergent extant lineages: Caviinae (cavies), Dolichotinae (maras), and Hydrochoerinae (capybaras). The fossil record of Caviidae is only abundant and diverse since the late Miocene. Caviids belongs to Cavioidea sensu stricto (Cavioidea s.s.) that also includes a diverse assemblage of extinct taxa recorded from the late Oligocene to the middle Miocene of South America (‘‘eocardiids’’). Results: A phylogenetic analysis combining morphological and molecular data is presented here, evaluating the time of diversification of selected nodes based on the calibration of phylogenetic trees with fossil taxa and the use of relaxed molecular clocks. This analysis reveals three major phases of diversification in the evolutionary history of Cavioidea s.s. The first two phases involve two successive radiations of extinct lineages that occurred during the late Oligocene and the early Miocene. The third phase consists of the diversification of Caviidae. The initial split of caviids is dated as middle Miocene by the fossil record. This date falls within the 95% higher probability distribution estimated by the relaxed Bayesian molecular clock, although the mean age estimate ages are 3.5 to 7 Myr older. The initial split of caviids is followed by an obscure period of poor fossil record (refered here as the Mayoan gap) and then by the appearance of highly differentiated modern lineages of caviids, which evidentially occurred at the late Miocene as indicated by both the fossil record and molecular clock estimates. -

A peculiar faunivorous metatherian from the early Eocene of Australia ROBIN M.D. BECK Beck, R.M.D. 201X. A peculiar faunivorous metatherian from the early Eocene of Australia. Acta Palaeontologica Polonica 5X (X): xxx-xxx. I describe Archaeonothos henkgodthelpi gen. et. sp. nov., a small (estimated body mass ~40-80g) tribosphenic metathe- rian from the early Eocene Tingamarra Fauna of southeastern Queensland, Australia. This taxon, known only from a sin- gle isolated upper molar (M2 or M3) is characterised by a very distinctive combination of dental features that, collective- ly, probably represent faunivorous adaptations. These include: a straight, elevated centrocrista; a metacone considerably taller than the paracone; a wide stylar shelf (~50% of the total labiolingual width of the tooth); reduced stylar cusps; a long postmetacrista; a small and anteroposteriorly narrow protocone; an unbasined trigon; and the absence of conules. Some of these features are seen in dasyuromorphians, but detailed comparisons reveal key differences between A. henk- godthelpi and all known members of this clade. A. henkgodthelpi also predates recent molecular estimates for the diver- gence of crown-group Dasyuromorphia. -
