SUNDICK Department of Anthropology, Western Michigan University, Kalamazoo, Michigan 49008 KEY WORDS Early Man North America ABSTRACT An analysis of a four to nine month old human infant with a possible date of at least 40,000 years, from Taber, Alberta, is presented. The specimen was found by A. MacS. Stalker in 1961 and has been reconstructed by the present author. The skeletal material derives primarily from the left side of the skull and face and, based on the degree of mineralization of the bone and the density of the matrix in which the material was embedded, it appears likely that the specimen is as old as has been suggested. The fact that only one side of the skull and face is present would indicate that erosion of the missing right side occurred before the specimen was embedded in the matrix. Loss of the right side after mineralization would have been unlikely because of the density of the matrix. RESUME L'Ctude d'un enfant humain 2gC entre quatre et neuf mois, associC A une date possible de 40,000 ans, provenant de Taber, Alberta, fait l'objet de cette communication. Le specimen fut dCcouvert par A. MacS. Stalker en 196 1 et a 6tC reconstituk par l'auteur. Les parties du squelette appartiennent principalement au c6te gauche du criine et de la face. Sur la base du degrC de minkralisation de 1'0s et de la densite de la matrice lors de sa dkcouverte, il semble possible que le sujet soit aussi ancien qu'on le sugghre. Le fait qu'un cbtC seulement du cr2ne et de la face ait 6tC prCservC semble indiquer que 1'6rosion de la partie droite manquante a eu lieu antkrieurement A l'ensevelissement du specimen dans la matrice de sa dkcouverte. La perte du c6tC droit apr6s minkralisation aurait CtC peu probable en raison de la densite de la matrice.
