Oldest record of Leptodactylus Fitzinger, 1826 (Anura, Leptodactylidae), from the early Pliocene of the South American Pampas
The Neotropical frog genus Leptodactylus is one of the most taxonomically diverse of all neobatrachian anurans. Despite the genus being highly diversified and widely distributed today, the fossil record is scanty and restricted to the Quaternary of the Neotropics. Here, we report and describe a new...
