Some methods have dated these to older than 200,000 years, others to less than 50,000 years.
Disputed evidence of the very late survival of H. erectus on the Indonesian island of Java exists in the form of fossil braincases (the part of the skull that encloses the brain) and a few other fragments. Some methods have dated these to older than 200,000 years, others to less than 50,000 years. The fossils show the characteristic H. erectus anatomy, but display brain sizes up to 50% larger than earlier examples of the species from the island.
