Takutu Formation (Guyana) |
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.[1] Fossil theropod tracks (a type of dinosaur) have been reported from the formation.[2][3] A paleobotanic analysis of drill cores of the formation was conducted by Thomas van der Hammen in 1966 and showed fossil flora.[1]
