Researchers recently discovered
fossils of cockroaches in Colorado dating back about 50 million
years. This species of cockroach was historically thought to have
originated in the Old World, now Europe, Asia and Africa, but this
recent discovery casts doubt on that assumption.
The fossils prove that this species of cockroach has been in the
Americas for a very long time.
