Ancient Seas, Eastern Europe, Poland, Holy Cross Mountains, Kowala Formation, Middle Devonian period (Givetian), ca. 387.7 to 382.7 million years ago. A large shale matrix containing sizable brachiopod fossils assembled across the surface. These are wonderfully preserved and three-dimensional examples of Schizophoria and Mucrospirifer brachiopods complete with both valves closed and intact. These brachiopods have been carefully extracted, cleaned, then arranged as a colony on a stone slab, much as how they would have been grouped underwater! With most brachiopod fossils found measuring less than 0.25 inches (0.635 cm) across, these brachiopods measure 3 to 5 times that size! Size of matrix: 10.5" L x 10" W (26.7 cm x 25.4 cm); brachiopods: 1.3" W (3.3 cm) to 0.8" W (2 cm)
This species of Schizophoria, of the middle Devonian era, is found in the Holy Cross Mountains in Poland. These mountains are a site dating back to the time of the world's oldest tetrapod footprints ever found - fossil evidence of the first existence of four-legged vertebrates walking on land. This is a large and very impressive display specimen of Devonian brachiopods, noteworthy for their famous scientific site in paleontology!
