Truly a museum grade display fossil slab of impressively large proportions, this is an amazing 100% NATURAL association of a mass extinction event displaying countless starfish and crinoid (sea lily) fossils, from the Ordovician Period. A specimen such as this with its impeccable preservation and dense concentration of multiple types of extinct sea life, is VERY UNCOMMON in the fossil record. Furthermore, the quality of the overall grouping as well as the intactness of the rock layer is something that is RARELY seen. If a museum wished to display an unforgettable and LARGE, visually impacting specimen of a mass extinction of various forms of co-existing marine life from nearly a half a billion years ago, this piece would be one that public visitors would likely remember and be duly impressed by! The starfish fossils are the largest and most 3D, lifelike examples we have ever seen from this region!
Many multiple Moroccan fossil slabs are artificially created by gluing together partial and complete trilobites on a rock base to make an impressive grouping. Such fossils are NOT rare and of little scientific value compared to a specimen such as this where all the fossilized life-forms died in this position as seen above and together in a layer. Some catastrophic event must have occurred to kill off so many of these at once. Perhaps a prehistoric tsunami.
All fossils on this plate are extremely three-dimensional and fully retain their lifelike appearance as when they were alive nearly a half a billion years ago. This is One of the most impressive fossil starfish / crinoid / marine life fossil we have ever seen. All the fossils were prepared exactly as they were originally buried with NO FABRICATION or adding of parts missing to the fossils. Again, from a scientific perspective, this is an EXTRAORDINARILY RAREspecimen because it is natural and so well preserved with such a large concentration of these different forms of prehistoric marine life.
For the ultimate commercial or residential interior design application or for a public museum exhibit, this is an extremely rare and interesting very large fossil slab of the finest scientific grade showing a rare and visually intriguing MUSEUM-CLASS fossil showing a MASS EXTINCTION event of some of the earliest complex marine life on our planet.
