Privately issued first report on Homo erectus. In 1891 Dubois discovered remains of what he described as "a species in between humans and apes" at Trinil, Java. He called his finds Pithecanthropus erectus ("ape-human that stands upright") or Java Man. Today, they are classified as Homo erectus ("human that stands upright"). These were the first specimens of early hominid remains found outside of Africa or Europe.
