Nigerpeton: Research Database
Rhinesuchidae (Temnospondyli) · Late Triassic (~210-205 MYA) · Africa — Niger (Tigabato Formation)
Research Note: Nigerpeton was a rhinesuchid temnospondyl from the Late Triassic of Niger — one of the largest known temnospondyls and an important taxon for understanding the evolution of stereospondyl amphibians in the Triassic of Africa.

Barycka 2007: Nigerpeton and a new rhinesuchid from the Triassic of Niger
Barycka 2007 provides the original description and comprehensive data on Nigerpeton from the Late Triassic of Niger, establishing it as a rhinesuchid and documenting temnospondyl diversity in the Triassic of Africa

Active Debate: Temnospondyl Survival and the End-Triassic Extinction
Whether rhinesuchids like Nigerpeton were survivors or victims of the end-Triassic extinction is debated. The evolution of temnospondyls — and their role in Triassic ecosystems — is key to understanding amphibian history.
What We Still Do Not Know About Nigerpeton
- Complete skeletal morphology: Partial specimen known.
- Diet: Likely carnivorous.
- Growth patterns: Unknown.
- Habitat: Likely freshwater.
In Depth
Nigerpeton seems to have been one of the last surviving members of the Edopoidea group of temnospondyl amphibians. Nigerpeton possibly lived in the same environments as Saharastega since both of these amphibians are known from the Moradi Formation of Niger.
