Macrauchenia

The first Macrauchenia skeleton was actually discovered by Charles Darwin on a stop-over on his famous journey on board The Beagle. Since then many more remains have been found in the Lujan formation in Argentina. Although this animal looked like it should be a member of the camel family, it was actually related to a group of animals that no longer exists - the litopterns. Its strange skull suggests that it had a muscular proboscis. Little work has been done on Macrauchenia, but its ankle joints and shin bones seem to be adapted for extreme mobility, allowing it to twist and turn to avoid pursuers at high speed.
