Deccanolestes is ascansorial,basalEuarchontan from theLate Cretaceous (Maastrichtian) andPaleoceneIntertrappean Beds ofAndhra Pradesh,India. It may be closely related toSahnitherium.Deccanolestes has been referred toPalaeoryctidae in the past, but recent evidence has shown that it is either the most basal Euarchontan,[1] as the earliest knownAdapisoriculid,[2] or as a stem-afrotherian.[3]

Species

[edit]

Deccanolestes hislopi is based on an isolated first upper molar (VPL/JU/NKIM/10). A third molar, a lower third premolar, various other isolated teeth, and some postcranial remains have been referred to it.[4]

Deccanolestes robustus is based on an isolated lower first molar. Isolated teeth and some ankle remains have also been referred to it.[5]

Deccanolestes narmadensis is based on an isolated rear molar.[6]

AlongsideBharattherium,Deccanolestes is among the two mammal taxa that survived theKT event in India.[7]
