Fossil SeaShell Ancient Rare Dinosaur Ocean Aquarium Home School Science Class

Description

They measure about 6-7" across and my research says they are a few million years old! From the Pliocene era perhaps?
Condition Details: They are interesting around the edges with large unique barnacles attached on the outside.
The one on the right is a couple pounds!
Both are included in this sale. Great as a starter set for someone interested in fossils. Perfect for Science Class!!
I ship very fast. Thanks for looking at my post.
