Xanthopsis Crab

Product description

An outstanding fossil crab, Xanthopsis vulgaris, discovered in Wahkiakum, Washington State, USA.

It dates from the Oligocene, 34 million years old.

The decapods, or ten footed crutaceans, are an order that includes crabs, crayfish, lobsters, prawns, and shrimps.
They have existed since the Permian Period, nearly 300 million years ago.

However, true, recognisable crabs, evolved around the Jurassic Period, some 150 million years ago.

Their general structure has changed little since then, and modern day crabs display the same proportions, and general ornamentation.

A crab of this quality from this location is rare, and it will make a great addition to a collection.

Size:  6.5cms x 5cms
