The oldest-known frog fossils date to even earlier. Scientists in Argentina have discovered excellently preserved fossil remains of the oldest-known tadpole, the larval stage of a large frog ...
In 2024, a tadpole specimen of N. degiustoi (MPM-PV 23540) was reported from the La Matilde Formation of Argentina, representing the oldest known tadpole and the first stem-anuran larva in the fossil record. Tadpoles of this species reached lengths of 15.9 centimetres (6.3 in), among the largest recorded in frogs living or extinct. [5]
Vieraella is an extinct genus of frogs from the Lower Jurassic (Early Pliensbachian to Toarcian) Roca Blanca Formation of Argentina, and one of the oldest true frogs known. . This genus is known by a single exceptionally well-preserved specimen, P.V.L. 2188, with at least eight presacrals vertebrae, free ribs, ulna and radius not fused, bony skull with some discoglossid charac

The fossil was collected in 1984 near Lake Kemp in Texas and kept in the expansive collection of the Smithsonian Institution's National Museum of Natural History in Washington, but was not ...
The oldest fossil "proto-frog" Triadobatrachus is known from the Early Triassic of Madagascar (250 million years ago), but molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 million years ago.
