Patagonian Farm Unearths 65-Foot Sauropod With Blended Lineages
A shepherd in Patagonia helped uncover a 65-foot sauropod, Bicharracosaurus dionidei, dating to about 155 million years ago. The skeleton shows a surprising mix of brachiosaurid and diplodocid features, suggesting it may be the first Jurassic brachiosaurid identified in South America and offering new clues about sauropod evolution in Gondwana.
