[2] While they do not sport a true tooth comb like modern lemurs, microwear patterns on their lower incisors suggest they engaged in fur grooming behaviors.
[3] Analysis of cranial and postcranial fossils by paleontologists suggest members of the family Omomyidae, including the genus Necrolemur, possessed highly specialized adaptations for leaping.
[6] N. antiquus is very well represented in many middle and late Eocene localities ranging from MP16 to MP18 and is thought to have been sympatric with members of the Microchoerus genus in Spain.
[6] This new phylogeny is supported by the intermediate size and morphological characters of N. anadoni compared to N. filholi and N. antiquus, particularly the progressive development of larger and more tubercular crests on the M2 and M3 across the three species.
The stem of the braincase is very narrow and the flanges of the posterior alisphenoid, which anchor muscles involved in chewing, overlap with the anterior wall of the bulla.
[9] There are high levels of intraspecific and intrageneric variability in the upper and lower dentition of Necrolemur, which has been attributed to spatial and temporal differences in environment and resource availability.
However, examination of microwear striations on the incisors shows scratches running perpendicular to the apex of the tooth crowns, which may be evidence of fur grooming behavior.
[2][3] Necrolemur cheek teeth are generally characterized by broad basins and blunt cusps, which suggests a diet made of soft fruit.
[10] Similarities between the foot of Necrolemur and tarsiers are best seen as evolutionary convergences, with the precise method of locomotion evolving independently from extant Tarsiiformes.
