Discovery of 65-Foot Dinosaur Fossils in Patagonia Challenges Existing Sauropod Classifications
A shepherd in Patagonia has discovered fossils of a 65-foot dinosaur, named Bicharracosaurus dionidei, which do not fit into any recognized dinosaur group. The fossils, found in the Cañadón Calcáreo Formation, date back 155 million years and exhibit a mix of features from both brachiosaurids and diplodocids. This discovery is significant as it represents the first Jurassic brachiosaurid identified in South America. The research, published in PeerJ, highlights the importance of the find in understanding the evolution of sauropods in the Southern Hemisphere. The fossils include more than 30 vertebrae, ribs, and part of the pelvis, providing new insights into the diversity of sauropods during the Jurassic period.
