Stingray

“One of the fun things about some of the fossils is, they tell stories,” Bowen said, pointing to a fossilized stingray hanging on the shop wall.

I was surprised to learn that a stingray can actually regenerate its stinger if it gets broken off.

The device mimics a cell phone tower and gets the phone to connect to it. […] Once a signal is found, the stingray measures its strength and can provide a general location on the map.
