That's a big bone

 

The dog must have been very excited.

A man walking his dog found a rare intact dinosaur skeleton

"Two years ago, Damien Boschetto decided to take his dog for a walk. He and Muffin, a border collie mix, headed over to a forest in Montouliers, a few miles from his home in Cruzy, in southern France.

While Muffin sniffed and explored the trail, Boschetto kept an eye out for fossils — a favorite pastime for him after studying paleontology in college. Soon he spotted something poking out from an eroded cliff. It was a bone. And a big one."

More about the fossil:

"For a titanosaur, this skeleton was on the smaller side. Boschetto estimates the one he uncovered was about 30 feet in length. The sediment level where it was found indicates it lived about 70 million years ago during the late Cretaceous era."
