Deccanolestes is a scansorial, basal Euarchontan from the Late Cretaceous (Maastrichtian) Intertrappean Beds of Andhra Pradesh, India. It may be closely related to Sahnitherium. Deccanolestes has been referred to Palaeoryctidae in the past, but recent evidence has shown the it is either the most basal Euarchontan,[1] as the earliest known Adapisoriculid,[2] or as a stem-afrotherian.[3]

Species

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]
