Fossil history Over 6,000 living species of Coccinellidae have been described. They are sparsely preserved in the fossil record. Although molecular clock estimates have placed their origin in the Cretaceous , the oldest fossils of the group are known from the Oise amber of France, dating to the Early Eocene ( Ypresian ) around 53 million years ago, which belong to the extant genera Rhyzobius and Nephus . The greatest number of fossils comes from the younger Eocene Baltic amber , including members of the extant genera Serangium and Rhyzobius as well as extinct genera belonging to the tribes Microweiseini ( Baltosidis ) and Sticholotidini ( Electrolotis ).
