Description:

Ancient seas, Paleozoic period, ca. 300 to 400 million years ago. A fantastic fossilized specimen that shows off a pair of well preserved brachiopods, a prehistoric clam, with both valves closed and displayed on a piece of shale. The top of one has an abrasion that reveals some of the interior crystalized quartz, a result of the fossilization process. These brachiopods are positioned on a piece of shale as they might have looked when in a colony comprised of dozens of other calms, and the shale also includes a partial shell fossil on its surface. Brachiopods are a type of clam with two shells, or valves, that died out during the Triassic extinction, but have over 400 living relatives in the clam and mollusk family today! Size of shale: 3.75" L x 1.75" H (9.5 cm x 4.4 cm); larger clam: 1.75" L (4.4 cm)

Provenance: ex-estate of Eldert Bontekoe, Pegasi Numismatics, Ann Arbor, Michigan, USA acquired before 2000
