While this is an extremely interesting and aesthetic large fossil slab showing a variety of prehistoric Ordovician marine life fossils, it includes two amazingly well preserved THREE DIMENSIONAL coral fossils that exhibit incredibly detailed preservation. In the 23 years of our travels and extensive work with Saharan material, we have never seen coral fossils from the Ordovician of this type! The slab would also make a monumental display piece demonstrating various forms of Ordovician sea life from well over 400 million years ago.
This remarkable fossil showcases a NATURAL mass death association of a variety of marine creatures. There are 2 coral fossils, a spectacular and large 6 inch Selenopeltis trilobite, another negative impression of another Selenopeltis trilobite but with most of the positive fossil spines attached to the impression, numerous unusually large onnia trilobites and numerous rare spiny-tailed Mucronaspis sp. trilobites, a Dalmanitid-type trilobite. This is a 100% NATURAL ASSOCIATION OF ALL FOSSILS SHOWN ON THIS SLAB. NONE HAVE BEEN ARTIFICIALLY ATTACHED as is common with many kinds of group fossils, especially from Morocco. The Selenopeltis trilobite is a spectacular specimen but the real celebrity of this piece are the two coral fossils, namely, the giant and bizarrely preserved FOOT LONG colony specimen! This fossil shows rarely seen large pore anatomy and a complete, full inflation coming off the rock. Up until this specimen, every coral fossil we have seen of this age from Morocco, had been nothing more than a faint, flat impression on the rock lacking any detail like this. These fossils on this example, exceed the quality of anatomical features and detail we have ever encountered in any North African specimen. Seldom are scientifically important fossils also impressive to the public but this specimen succeeds on both accounts! This is the most impressive and fine example of its kind we have ever come across.
