Summary
[edit]DescriptionFish bone (Chattanooga Shale, Upper Devonian; Burkesville West Rt. 90 roadcut, Kentucky, USA) 1 (41446569415).jpg |
Fossil fish bone in the Devonian of Kentucky, USA. This is a piece of fossil fish bone - it is probably derived from a placoderm, an extinct group of mostly predatory, jawed fish (exemplified by Dunkleosteus - <a href="https://www.flickr.com/photos/jsjgeology/33974292562">www.flickr.com/photos/jsjgeology/33974292562</a>). The fossil was found in the basal Chattanooga Shale, a unit of dark-colored, chippy-weathering, marine mudshales of Late Devonian age. These black shales were deposited in a moderately deep, anoxic seafloor environment. This was a widespread lithofacies during the Late Devonian's Global Anoxia Event. The Chattanooga Shale is equivalent to the Ohio Shale, the Antrim Shale, and the New Albany Shale in surrounding states. Classification: Animalia, Chordata, Vertebrata, Placodermi Stratigraphy: basal Chattanooga Shale, Upper Devonian Locality: roadcut on the northern side of Route 90, just west of Burkesville, central Cumberland County, southern Kentucky, USA (36° 47’ 51.17” North latitude, 85° 23’ 10.62” West longitude) |
