Overview
changeLeiopelmatidae have an extra vertebrae. They have the remains of the tail muscles.
When Leiopelmatid jump, they land in a "belly flop". After landing, Ascaphus skids to a halt before recovering.
They are very small frogs, only 5 centimetres (2.0 in) in length. Most species lay their eggs in moist ground, typically under rocks or plants. After hatching the tadpoles nest in the male's back. They do not need standing or flowing water. Life span may be long at more than 30 years.[4]

Much older fossils, dating back to the Jurassic, have been found in Argentina, such as Notobatrachus.
