Scientists have identified a new dinosaur species approximately 155\nmillion years old discovered in Patagonia, Argentina. The species named\nBicharracosaurus dionidei is believed to have lived during the Late\nJurassic period and provides key insights into sauropod evolution in the\nSouthern Hemisphere.<\/p>\n
The discovery, published in the journal PeerJ, has drawn global\nattention as Bicharracosaurus dionidei exhibits a combination of\nphysical traits from two distinct giant groups. Its skeletal structure\nshows similarities to Brachiosauridae (such as Africa\u2019s Giraffatitan)\nwhile also possessing vertebral characteristics resembling those of\nNorth America\u2019s Diplodocidae.<\/p>\n
Fossils found in the Ca\u00f1ad\u00f3n Calc\u00e1reo Formation, Chubut Province,\nconsist of over 30 vertebrae, ribs, and part of the pelvis. With an\nestimated length of 20 metres, this adult dinosaur provides new data on\nsauropod distribution when South America was part of the Gondwana\nsupercontinent.<\/p>\n
Lead researcher Alexandra Reutter explained that phylogenetic\nanalysis places the species within the Brachiosauridae group. If\nconfirmed, this fossil would be the first Jurassic-era Brachiosauridae\nspecimen found in South America.<\/p>\n
Unique Discovery Facts:<\/p>\n
Previously, references on Southern Hemisphere sauropods from the\nJurassic period were dominated by findings from Tanzania, Africa. The\npresence of Bicharracosaurus dionidei in Argentina fills a knowledge gap\nregarding how giant dinosaurs evolved and spread across the southern\nregions of the globe.<\/p>\n
Although the skeletal remains are not fully complete, researchers\nbelieve the unique combination of characteristics in this species\nindicates a closer evolutionary relationship between Brachiosauridae and\nDiplodocidae than previously thought.<\/p>", "url": "https:\/\/jawawa.id\/newsitem\/new-dinosaur-species-bicharracosaurus-dionidei-discovered-in-argentina-1780078207", "image": "" }, "sponsor": "Okusi Associates", "sponsor_url": "https:\/\/okusiassociates.com" }
