🦕 Your dog couldn't dig up this bone...

In 2017, an anonymous resident of Pombal, Portugal, found a few mysterious fossils in his backyard while finishing construction work, so they called a research team to come collect the pieces.

• A five-year-long excavation ensued, and scientists now believe the remains of the largest sauropod dinosaur ever found in Europe were hiding in the resident's backyard.

🔦 The ultimate treasure hunt: Sauropods were four-legged herbivorous dinosaurs with long necks and tails. So far, an “important set of elements of the axial skeleton” has been collected from the 82-foot-long dino.
