Amateur paleontologist and kid, A.J.R. shocked the world today when he presented one huge sauropod thigh bone to his dogs Bucky and Satchel.

After discovering a bone of the dinosaur Brachiosaurus in his backyard, A.J. spent a whole hour washing the bone to make sure it was free of germs. It then took him five hours to drag the monstrosity into the house. Bucky and Satchel were ecstatic upon seeing their new toy. A.J. predicts the bone will last them ten years.

Now, if only they can figure out how to get their teeth around it.
