Prosalirus is a prehistoric genus of frog from the Early Jurassic period of Arizona. Its name comes from the Latin verb prosalire meaning "to leap forward". It is a primitive frog, but it has lost the salamander-like tails of its ancestors, such as Triadobatrachus. It is the earliest frog species whose legs are specialized for jumping.
In The Land Before Time
A frog or toad, possibly Prosalirus, appears in The Land Before Time Animated Moviebook's Swamp Bubble Spelling Bee minigame, during a presentation of the word "Toad".
