Possible Jurassic brachiosaurid in South America
Bicharracosaurus dionidei might be the first Jurassic-era brachiosaurid spotted in South America, according to researcher Alexandra Reutter.
Professor Oliver Rauhut says the fossils help fill gaps about how giant dinosaurs spread across ancient continents like Gondwana.
The name honors Dionide Mesa, the shepherd who discovered the fossils (now safely kept at a museum in Trelew, Argentina).
