The Galula Formation is a geological formation located south of Lake Rukwa in Tanzania, part of the Red Sandstone Group of the Rukwa Rift Basin. Along with the unconformably overlying Oligocene Nsungwe Formation. It is divided into two members, the lower Mtuka Member and the upper Namba Member.{{Cite journal|last1=Roberts|first1=Eric M.|last2=O’Connor|first2=Patrick M.|last3=Stevens|first3=Nancy J.|last4=Gottfried|first4=Michael D.|last5=Jinnah|first5=Zubair A.|last6=Ngasala|first6=Sifael|last7=Choh|first7=Adeline M.|last8=Armstrong|first8=Richard A.|date=May 2010|title=Sedimentology and depositional environments of the Red Sandstone Group, Rukwa Rift Basin, southwestern Tanzania: New insight into Cretaceous and Paleogene terrestrial ecosystems and tectonics in sub-equatorial Africa|journal=Journal of African Earth Sciences|volume=57|issue=3|pages=179–212|doi=10.1016/j.jafrearsci.2009.09.002|bibcode=2010JAfES..57..179R |issn=1464-343X}}

The age of the deposit is poorly constrained, with the Mtuka Member likely being Aptian to Cenomanian in age, while the Namba Member being Cenomanian to Campanian in age based on Geomagnetic reversals.{{Cite journal|last1=Widlansky|first1=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|bibcode=2018JAfES.139..403W |issn=1464-343X|doi-access=free}} It is correlated with the Dinosaur Beds of Malawi.

The formation is fossiliferous, with Dinosaurs and Crocodyliformes being known from the formation.
