Another ginormous dinosaur from Argentina

We’ve got a new contender for biggest dino:

A team of scientists in Argentina have unearthed the remains of the largest species of dinosaur discovered to date, paleontologists announced Saturday.

Seven “huge” herbivorous dinosaurs were discovered at one site in the province of Chubut, Argentina, according to the Paleontological Museum Egidio Feruglio, which led the dig.

The new species are estimated to have been 40 meters in length and 80 tons in weight, surpassing the previous record-holder for the world’s largest dinosaur — the Argentinosaurus.

These dinosaur size rankings always come with a few caveats. Back in the 1870s, a fossil collector working for the famous naturalist Edward Drinker Cope found part of a backbone and femur from a long-necked dino that Cope named Amphicoelias fragillimus.  Comparing Cope’s report of the remains’ size to the same parts from better-known dinos indicates that A. fragillimus was far and away the longest dinosaur of all time—as in close to 200 feet from tip to tip.  The problem is, Cope’s published account is all we have, because the bones themselves are gone.  It’s possible they were in such a poor state of preservation that they just crumbled to pieces.

And a reported dino from India named Bruhathkayosaurus supposedly approached Amphicoelias in size, but the initial description was iffy and the specimen got washed away in a flood.

Anyway, this latest find means yet another humungous dinosaur from Argentina, a country with a track record of producing some of the biggest of all terrible lizards.  In addition to Argentinosaurus, it was also home to Giganotosaurus, one of the biggest carnivorous dinos.  We’ll be seeing him again in the very near future.  (Here on the blog, I mean, not out in the real world.  That would either be really, really awesome or really, really unfortunate.)
