The Dinosaur Beds is a geological formation in Malawi whose strata date back to the Early Cretaceous. The age of the deposit is poorly constrained, but is likely to date from the Barremian to Aptian.[1] Dinosaurs, turtles and crocodyliomorphs remains are among the fossils that have been recovered from the formation.[2] It is correlated with the Galula Formation in Tanzania. It consists of two members, a lower unfossiliferous member comprised of deep red stained sandstones, and a upper fossiliferous member comprised of white sands and grey to red mudstones and siltstones.
Vertebrate paleofauna
- Karongasaurus gittelmani - A lower mandible and a few teeth
- Malawisaurus dixeyi - "Skull elements, teeth, vertebrae, limb elements osteoderms, of several individuals."[3]
- Malawisuchus mwakasyungutiensis - A skeleton (almost complete articulated skeleton and skull)
- Platycheloides nyasae - A partial shell
- Theropoda indet.
