Deccanolestes is a scansorial, basal Euarchontan from the Late Cretaceous (Maastrichtian) and Paleocene 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 that it is either the most basal Euarchontan, [1] as the earliest known Adapisoriculid, [2] or as a stem-afrotherian.

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]

Alongside Bharattherium , Deccanolestes is among the two mammal taxa that survived the KT event in India. [7]
