The Indian and Javan rhinoceroses, the only members of the genus Rhinoceros, first appear in the fossil record in Asia around 1.6 million3.3 million years ago. Molecular estimates, however, suggest the species may have diverged much earlier, around 11.7 million years ago. Although belonging to the type genus, the Indian and Javan rhinoceroses are not believed to be closely related to other rhino species. Different studies have hypothesized that they may be closely related to the extinct Gaindatherium or Punjabitherium.
A detailed cladistic analysis of the Rhinocerotidae placed Rhinoceros and the extinct Punjabitherium in a clade with Dicerorhinus, the Sumatran rhinoceros. Other studies have suggested the Sumatran rhinoceros is more closely related to the two African species.
The Sumatran rhino may have diverged from the other Asian rhinos as long as 15 million years ago. The item "VERY RARE Indonesian FOSSIL RHINO, RHINOCEROS TOOTH! 1.6-3.3 MILLION YEARS OLD" is in sale since Sunday, February 7, 2021.
