β¦ Synopsis
Until the 1980s all interpretations of the deciduous dental formulae of the unusual and endangered prosimian primate Daubentonia mudagascariensis were based on a publication more than 125 years old [Peters, 1866al. Rather than being based on original material all later interpretations were exclusively derived from Peters' figures and descriptions. A relatively recent attempt by Luckett and Maier [19861 to establish the true milk dentition of the aye aye was based on histological evaluation of a late aye aye fetus from the collection of W.W. Hubrecht that was chemically preserved at least 80 years earlier. The death of a newborn aye aye at the Duke University Primate Center in 1992 finally made the following new evaluation of the D. mdagascariensis deciduous tooth formula possible.
Using X-rays and dissection, it here is demonstrated that aye ayes have one incisor, one canine, and two premolars in both the upper and in the lower milk dentition. Therefore the deciduous dental formula of Daubentonia mdagascariensis should read: l i l c 2p li * l c .2p '

Aye-ayes (Daubentonia madagascariensis) have unique hands among primates, with extraordinarily long fingers in relation to body size. These long digits may be vulnerable to damage from forces during locomotion, particularly during head-first descent-a locomotor mode that the aye-aye utilizes frequen
