In 1970 it was identified as an Archaeopteryx by paleontologist John Ostrom, who called it the "Haarlem specimen", since it was kept in the Teylers Museum in Haarlem. In 2017 Christian Foth and Oliver Rauhut concluded it was more closely related to the Chinese Anchiornis and introduced the generic name Ostromia, named after Ostrom.
