''A. hedei'' has proven so far to be the earliest-known actinopterygiian, living around 420 million years ago. Both species inhabited Russia, and ''A. hedei'' fossils have also been uncovered in Sweden, Estonia, and Latvia.〔(''Andreolepis'' (Actinopterygii) in the Upper Silurian of Northern Eurasia )〕 ==References==
