Palaeolagus was an ancient rabbit that lived during the Ice ages.
Palaeolagus had long ears and large feet. Palaeolagus were similar to Rabbits, but had shorter hind limbs than living rabbits, meaning that it was probably unable to hop. They were great runners and are thought to have ran similar to a ground squirrel.
Palaeolagus are an extinct genus of lagomorph. They lived in the Oligocene period which was about 33-23 million years ago. The earliest leporids described from the fossil record of North America and Asia date to the upper Eocene some 40 million years ago.
