Check out this massive dinosaur femur just found in France

This week, French paleontologists unearthed a two-meter long dinosaur femur in southwestern France. From Reuters:

The... femur at the Angeac-Charente site is thought to have belonged to a sauropod, herbivorous dinosaurs with long necks and tails which were widespread in the late Jurassic era, over 140 million years ago.

This is a major discovery, Ronan Allain, a paleontologist at the National History Museum of Paris told Reuters. I was especially amazed by the state of preservation of that femur.

These are animals that probably weighed 40 to 50 tonnes.
