Mahajangasuchus: Research Database
Crocodyliformes (Reptilia) · Late Cretaceous (~70 MYA) · Africa — Madagascar
Research Note: Mahajangasuchus was a crocodyliform from the Late Cretaceous of Madagascar — a large, powerful predator and an important taxon for understanding crocodilian evolution on Madagascar.

Active Debate: Top Predator Roles on Late Cretaceous Madagascar
Whether Mahajangasuchus was the apex predator on Madagascar is debated. The evolution of large predators on islands — and their ecological roles — is key to understanding Cretaceous island biogeography.
What We Still Do Not Know About Mahajangasuchus
- Complete skeletal morphology: Partial specimen known.
- Diet: Likely carnivorous.
- Social behavior: No direct evidence.
- Ecology: Unclear.
In Depth
Not much is known about Mahajangasuchus, but the robust skull suggests a strong bite force even for a crocodile. The teeth of Mahajangasuchus were also conical and fairly blunt suggesting that they were used on larger prey like land animals rather than small prey like fish.
Mahajangasuchus has been moved around quite a bit in its classification history. Currently Mahajangasuchus resides within the Mahajangasuchidae along with the ‘boar croc’, Kaprosuchus.
