Stego torso

Stego torso is one of the 3 pieces of the Stegosaurus fossil. Dig up fossils at the cracks on the ground, have Blathers assess them, then donate it to the museum or sell spares for 4,500 Bells.

Stegosaurus was a Late Jurassic plant eater with tall plates along its back and sharp spikes on its tail. More time separates it from T. rex than separates T. rex from us.
