HUGE 4 Cambrian Period Trilobite Fossils Slate Rock North America 10″ 9″ 8″ 5″

I am very pleased to offer this beautiful Piece of Earth History!  This huge slate contains 4 large Trilobite fossils.  There is a 10″ L x 5-3/4″ W Fossil, a 9″ L x 6″ W Fossil, a 8″ L x 5-1/2″ W Fossil, and a 5″ L x 4″ W fossil clustered together on the top of the slate.

The fossils have fairly good detail in the spines.

I am not an expert in fossils, however I do know that this piece was purchased in Florida, and strongly resembles the mid-Cambrian period (542-488 million years ago) Redlichiida (please advise if you know a lot about Trilobites)  

The slate is rather large, and measures in total approx. 20″ L x 18-1/2″ W x 2″ Tall.

This piece is in very good display condition.  It is surprisingly fragile, and there are numerous cracks and chips to the slate.  The piece will be throughly packed for safe shipping with full insurance.
