Evolutionary ‘game-changer’: weird armoured amphibian lived in ancient seas

How the science connects

Triassic period

AI Insight

Scientists have discovered an unusual armoured amphibian that inhabited ancient seas during the Late Triassic period. The creature possessed protective armour plating that researchers believe allowed it to adapt to and survive in the saline marine environments of that era, which would have been challenging for typical amphibians. This finding represents a significant evolutionary adaptation, as amphibians are generally associated with freshwater habitats.


This discovery challenges conventional understanding of amphibian evolution and habitat tolerance, demonstrating that some ancient amphibians developed specialized adaptations to survive in marine environments. The finding provides important insights into how vertebrates adapted to diverse and extreme environmental conditions during the Triassic period.

The creature’s armour cladding probably enabled it to tolerate the salty seas of the Late Triassic.
