Karongasaurus: Research Database
Titanosauria (Sauropoda) · Late Cretaceous (~100–84 MYA) · Gondwana — Malawi (Karonga Basin, Dongas Formation)
Research Note: Karongasaurus was a titanosaurian sauropod from the Late Cretaceous of Malawi — one of the few named dinosaurs from Africa. As a member of the Titanosauria, it provides data on African Cretaceous dinosaur faunas and gondwanan titanosaur biogeography.

Active Debate: African Dinosaur Biogeography, Gondwanan Titanosaur Evolution, and the K-Pg Extinction
Whether African titanosaurs like Karongasaurus were part of an endemic African radiation or whether they were related to South American or Asian titanosaurs is debated. The African Cretaceous dinosaur record is limited.
The extinction of African dinosaurs — and whether African dinosaur faunas were fundamentally different from those of other continents — is a question of ongoing research.
What We Still Do Not Know About Karongasaurus
- Complete skeletal morphology: Partial specimens known.
- Body mass: Estimated.
- Social behavior: No direct evidence.
- Armor: Unknown.
In Depth
Although named from only partial remains, Karongasaurus is truly a dinosaur genus of the information age since its description was the first to be published solely online. The genus name Karongasaurus is in reference to the Karonga district of Malawi combined with the Ancient Greek for ‘lizard’. The species name is in honour of Steve Gittelman.
The mandible that makes up the holotype (Mal-175) hints that the skull of Karongasaurus would have been quite long. There has been past speculation that this mandible may actually be from a juvenile of another genus of called Malawisaurus, another sauropod that has been named from the same formation as Karongasaurus. However Malawisaurus has a skull that is proportionately quite short, so unless it is proven that the mandible of Karongasaurus is from something like a juvenile Malawisaurus, which had yet to change into adult form, the two genera are likely to remain regarded as separate.
