Forskare har beskrivit en tidigare okänd sauropod-dinosaurie från fossil som hittats i provinsen Chubut i Argentina. Varelsen, som fått namnet Bicharracosaurus dionidei, blev omkring 20 meter lång och levde för ungefär 155 miljoner år sedan.

Forskare har funnit mer än 30 kotor, flera revben och en del av bäckenet från bergformationen Cañadón Calcáreo. Benen tillhörde ett vuxet djur och uppvisar en blandning av egenskaper som ses hos både brachiosaurider och diplodocider. Alexandra Reutter, studiens huvudförfattare och doktorand vid LMU, ledde analysen av lämningarna som nu förvaras på Museo Paleontológico Egidio Feruglio i Trelew.
