Monte Bolca
Bolca, Italy
Monte Bolca is an Early Eocene-aged geologic site located near Verona, Italy. A Konservat-Lagerstätte, it contains an extremely well-preserved and diverse marine biota, including the most diverse fish fauna of any Cenozoic fossil site, as well as many of the earliest fossil occurrences of modern marine fish groups. It was one of the first fossil sites with high quality preservation known to Europeans, with studies of its biota dating back to the 18th century and earlier, and is still an important source of fossils.
