''Chubutinectes'' (meaning "Chubut Province, Chubut swimmer") is an extinct genus of elasmosaurid plesiosaur from the Late Cretaceous La Colonia Formation of Argentina. The genus contains a Monotypic taxon, single species, ''C. carmeloi'', known from a partial skeleton and associated gastroliths. Discovery and naming The ''Chubutinectes'' holotype specimen, Museum of Paleontology Egidio Feruglio, MPEF-PV 5232, was discovered in 2009 within sediments of the La Colonia Formation on the North Patagonian Massif, Somún Curá plateau in Chubut Province, Argentina. The Joint, disarticulated specimen consists of Cervical vertebrae, cervical, pectoral, Dorsal vertebrae, dorsal, Sacral vertebrae, sacral, and caudal vertebrae, caudal vertebral centra and neural arches, various ribs, partial Shoulder girdle, pectoral and Pelvis, pelvic girdles, fore- and hind-limb elements, and about 350 gastroliths. In 2023, O'Gorman and colleagues Species description, described ''Chubutinectes carmelo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
La Colonia Formation
The La Colonia Formation is a geological Formation (geology), formation in Argentina whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.Weishampel et al., 2004, pp.600-604 Originally thought to be Campanian (c.73-72 million years ago) in age or earlier, studies of underlying formations have made a Maastrichtian (72–66 million years ago) age more likely.Rauhut, 2003 Description It is divided up into three distinct facies, the first is up to thick and consists of conglomerate (geology), conglomerate, the second is by far the thickest at over , consists of siltstone and claystone, with interbeds of claystone/shale and sandstone, the third is less than thick and consists of clay, and probably represents a nearshore marine depositional environment, environment. The paleoflora was known for its aquatic components, ''Paleoazolla'' and ''Regnellidium''. However, recent paleobotanical discoveries at ...
