The biggest dinosaur… debatable

It would have weighed more than 10 African elephants put together and had a thighbone taller than the man who helped dig it up. A team of researchers finally decided what to call this new species of prehistoric colossus: Patagotitan mayorum. The name roughly translates to the “giant from Patagonia” — with a nod to the Mayo family, which own the farm where the fossils were found.

Researchers say the size of the femur (from the thigh) and humerus (from the upper arm) suggests the species’ mass outpaces other massive sauropods that have had those two bones preserved. And because Patagotitan‘s skeleton was so complete when recovered, they were able to arrive at separate estimates — through three-dimensional modeling — that “represent approximately twice (or more) the body mass inferred by the same volumetric methods for other sauropods.”

Yet some paleontologists remain unconvinced the find represents an undisputed record. Rather, given the margin of error surrounding such size estimates — especially estimates of other massive (but far less complete) sauropod skeletons — paleontologist Mathew Wedel argues the competition for World’s Largest Dinosaur™ is closer to a “three-way tie” between Patagotitan and two other titanosaurs, Argentinosaurus and Puertasaurus.

I don’t know about you guys, but I’m about to start googling the above three dinosaurs so I can have an informed opinion about which one is the largest. Goodbye productivity for today… hello massive dinosaurs.
