  Dinosaur Beds (Malawi) | |
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 consisting of deep red stained sandstones, and an upper fossiliferous member consisting of white sands and grey to red mudstones and siltstones. The upper member is 210 m thick in the vicinity of the CD-9 locality.[3]
Vertebrate paleofauna
