Scientists in Argentina have discovered excellently preserved fossil remains of the oldest-known tadpole, the larval stage of a large frog species that lived alongside dinosaurs about 161 million ...
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]
Tadpoles of N. degiustoi constitute the oldest tadpoles found as of 2024, dating back to 168–161 million years ago. These tadpoles also showed adaptations for filter-feeding, implying residence in temporary pools by filter-feeding larvae was already commonplace. [37] The evolution of modern Anura likely was complete by the Jurassic period.
The team later found associated evidence of stone tool use (a core, scrapers, cutting blades, and a spear point) in the same area that is believed to date from the same period. There was also evidence of the use of ochre , leading to the intriguing possibility that the 'Eve' of 117,000 years ago may have been wearing the colourful powder.
