Time period: Late Miocene.
Fossil representation: Skull.
in 1972 by Dimitar Kovachev, Kalimantsia did
not get named until
2001. Although based upon the description of a skull, Kalimantsia
is known to have had a shorter snout than many other known
chalicotheres, something that might suggest a foraging specialisation
in tougher types of vegetation that required a stronger bite (an
ability provided by the shorter muzzle allowing the jaw closing muscles
to focus upon a smaller area). If correct then Kalimantsia
have been analogous to the short faced prehistoric kangaroos of
Australia such as Procoptodon
in terms of ecological niche.
The most striking feature of Kalimantsia is the high domed skull. This is quite unusual for a chalicothere when you consider that most of the known genera had heads proportioned similar to those of horses. This dome has been speculated to not only be for display but for use in head butting or pushing contests between two rival Kalimantsia. Another dome headed chalicothere is Tylocephalonyx from North America.
