Gomphos elkema is an ancestor of the rabbits and hares who lived 55 million years ago. Fossil remains were discovered by researchers working with Robert Asher from the Berlin Museum of Natural History in the Nemegt basin of the Gobi desert ( Mongolia ).
As with today's rabbits, which belong to the order of the hare-like (Lagomorpha), the incisor teeth of Gomphos elkema grew back. Gomphos elkema had long hind legs, which made it possible for him to hop along. More like today's squirrels (and thus rodents ) have a longer tail and pointed molars.
