Adalatherium hui (Krause et al. 2020; Late Cretaceous) was originally considered a relative of multituberculates. The LRT nests Adalatherium with stylinodontid adapids within the clade Primates. The large adapid also from Madagascar, Megaladapis is an ancestor.

Vintana sertichi (Krause et al. 2014; Late Cretaceous, UA 9972; 12.4 cm skull length; is a Madagascar mammal originally considered a member of the Allotheria and Gondwanatheria, two clades that do not appear in the large reptile tree. The LRT nests Vintana with stylinodontid adapids within the clade Primates. The large adapid also from Madagascar, Megaladapis is an ancestor.

Krause et al reported, “The new taxon is the largest known mammaliaform from the Mesozoic of Gondwana. Its craniofacial anatomy reveals that it was herbivorous, large-eyed and agile, with well-developed high-frequency hearing and a keen sense of smell. The cranium exhibits a mosaic of primitive and derived features, the disparity of which is extreme and probably reflective of a long evolutionary history in geographic isolation."
