The sauropod dinosaurs—the classic long-necks—included the largest land animal species that have ever lived. Throughout the Jurassic and Cretaceous, multiple families of sauropods achieved body masses over 50 tons: greater than any modern elephant and even exceeding the colossal indricothere rhinoceroses. Despite their incredible sizes, the sauropod dinosaurs have a murky early history…
This Past Time episode features a brand new species of sauropod cousin from the Early Jurassic of South Africa: Ledumahadi mafube. Described in a new paper in the journal Current Biology, Ledumahadi is part of a group of dinosaurs traditionally called “prosauropods.” Unlike the straight, column-like legs of true sauropods, Ledumahadi has strong but flexed arms and legs that lacked weight-bearing adaptations of its later cousin. Despite these anatomical differences, this new colossus achieved a mass over 12 tons, upending our classic understanding of the evolution of gigantic size!
The awesome art used for our promo image is work by Viktor Radermache, an up-and-coming paleoartist who has also worked on other finds out of the Evolutionary Studies Institute. Check out this cool interview with him for some more science and artwork. I added myself to the artwork in the front under Creative Commons 4.0.
