The '''Dinosaur Beds''' is a geological [[Formation (geology)|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]].<ref>{{Cite journal|last=Widlansky|first=Sarah J.|last2=Clyde|first2=William C.|last3=O'Connor|first3=Patrick M.|last4=Roberts|first4=Eric M.|last5=Stevens|first5=Nancy J.|date=March 2018|title=Paleomagnetism of the Cretaceous Galula Formation and implications for vertebrate evolution|journal=Journal of African Earth Sciences|volume=139|pages=403–420|doi=10.1016/j.jafrearsci.2017.11.029|issn=1464-343X}}</ref> Dinosaurs, turtles and crocodyliomorphs remains are among the fossils that have been recovered from the formation.<ref name="cretaceousdistribution">Weishampel, David B; et al.

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.<ref>{{Cite journal|last=WINKLER|first=DALE A.|last2=GOMANI|first2=ELIZABETH M.|last3=JACOBS|first3=LOUIS L.|date=2000|title=COMPARATIVE TAPHONOMY OF AN EARLY CRETACEOUS SAUROPOD QUARRY, MALAWI, AFRICA|url=https://www.researchgate.net/publication/274082885|journal=Paleont.
