Template:Short description Script error: No such module "Infobox".Script error: No such module "check for unknown parameters". The Tiki Formation is a Late Triassic (Carnian to Norian) geologic formation in Madhya Pradesh, northern India. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.[1] Phytosaur remains attributable to the genus Volcanosuchus have also been found in the Tiki Formation.[2]

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

Cynodonts

Cynodonts of the Tiki Formation
Genus Species Material Notes
Gondwanadon[3][4] G. tapani A single molar A morganucodont
Inditherium[5] I. floris[5] Three postcanine teeth A dromatheriid
Rewaconodon[3] R. indicus[5] A partial jaw and three postcanine teeth A dromatheriid
R. tikiensis[6]
Ruberodon[3][7] R. roychowdhurii Five partial jaws A traversodontid
Tikiodon[3] T. cromptoni A single postcanine tooth A mammaliamorph
Tikitherium[3][8] T. copei A single postcanine tooth A mammaliaform. Initially described as a basal mammaliaform related to Docodonta, but later redescribed as a Neogene shrew fossil that was reworked into the older deposit.[9]
Cynodontia indet.

Reptiles

Teeth similar to Galtonia, Protecovasaurus,[10] and Azendohsaurus[11] are known from the formation. Claws similar to shuvosaurids and dinosaurs[12] have also been reported, though their exact identification is questionable. Saurischian dinosaurs may have been present based on vertebrae and limb fragments.[13]

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.
