Ankylo tail

Ankylo tail is one of the 3 pieces of the Ankylosaurus fossil. Dig up fossils at the cracks on the ground, have Blathers assess them, then donate it to the museum or sell spares for 2,500 Bells.

Ankylosaurus was a Late Cretaceous plant eater wrapped in armour made of bony plates. The end of its tail formed a solid club, which it probably swung to fend off predators.
