Thus, we do not consider either of these factors to have contributed significantly to their extinction.

Here we report on uranium-series dating of a stegodon tusk recovered from the Ainaro Gravels of Timor.

The six dates obtained indicate the local presence of stegodons in Timor at or before 130 ka, significantly pre-dating the earliest evidence of humans on the island.
