These images showcase Triassic micro fossils found in bone bed matrix from the Rhaetian Age of the Triassic Period at Aust Cliff, UK. They are approximately 200 million years old.
I am fortunate to have been sent this rich matrix from the UK by a fellow avocational paleontologist across the pond.
The photographs of the very fragile fish and shark fossils were made with my DinoXcope and stacked with Zerene Stacker. The scale is one millimeter.
