Plesio tail

Plesio tail is one of the 3 pieces of the Plesiosaurus 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.

Plesiosaurus was an Early Jurassic marine reptile with a long neck and four big flippers for paddling. In 1823 fossil hunter Mary Anning dug up the first complete skeleton on England's south coast.
