Modocia weeksensisDescription: This plaque displays a complete example of a trilobite of the Order Ptychopariida, known as Modocia weeksensis. It is easy to see where the species derives its name. They are typically found missing the genals, and as such are mostly molts. It is a large, well-inflated example that would make a welcome addition to any trilobite collection.
