Fish tail fossil on slate - 75g (Poland), on black stand

This fish tail fossil, embedded in a slate slab, comes from the Eastern Carpathians in Poland. Dating back about 30 million years, this piece testifies to a geological period when the seas covered much of Europe. The fossilization of fish on slate is a rare phenomenon, offering a spectacular contrast between the mineralized remains of the fish and the dark rock that surrounds them. This species is of the family of the Thuna fishes and corresponds to the emergence of these super predators on earth.
The pronounced striations and the distinct shape of the fish tail add an artistic dimension to this piece, making it ideal for collectors and enthusiasts of natural curiosities.
