The Tiki Formation is a Late Triassic (Carnian to Norian) geologic formation in Madhya Pradesh, northern India.[1] Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.[2] Phytosaur remains attributable to the genus Volcanosuchus have also been found in the Tiki Formation.[3]

The genera Tikiodon, Tikitherium and Tikisuchus and species Rewaconodon tikiensis, Hyperodapedon tikiensis and Parvodus tikiensis have been named after the Tiki Formation.

Correlations

The Tiki Formation is considered a temporal equivalent of the Lower Maleri Formation. The majority of the Tiki Formation correlates with the Ischigualasto Formation of Argentina, the upper part of the Santa Maria Formation, and the overlying lower Caturrita Formation of Brazil, the Isalo II Beds of Madagascar, Lossiemouth Sandstone of Scotland, and the lower Tecovas Formation of the Chinle Group of North America.[1]
