Takutu Formation

The Takutu Formation is a Late Jurassic geologic formation in Guyana and northern Brazil. The formation comprises sandstones deposited in a shallow water to littoral setting. Fossil theropod tracks (a type of dinosaur) have been reported from the formation. A paleobotanic analysis of drill cores of the formation was conducted by Thomas van der Hammen in 1966 and showed fossil "Classiopolis" flora.
