The Postcranial Anatomy of Australopithecus afarensis

Part of the book series: Vertebrate Paleobiology and Paleoanthropology ((VERT))

Abstract

Early hominin partial skeletons are extremely rare in the fossil record, particularly for the time predating 3 Ma (million years ago). As a result, most of our understanding of Pliocene hominin paleobiology and phylogenetic relationships is based on isolated and fragmentary specimens. The Middle Pliocene species Australopithecus afarensis is one of the best-known early hominin species, and yet only three adult partial skeletons of the species have been recovered thus far, including the one described in this volume. The best known of these is the 3.2 Ma partial skeleton of a small female (A.L. 288-1 ) from Hadar , Ethiopia, and much of our understanding of the paleobiology of this species has been influenced by this specimen. The newly recovered 3.6 Ma partial skeleton from the Woranso-Mille, Ethiopia (KSD-VP-1/1 , aka Kadanuumuu ) represents a much larger male individual and may provide us with fresh insights into the paleobiology of Au. afarensis . This specimen not only preserves elements of the forelimb and hindlimb, but also includes complete elements, such as the scapula and clavicle , which were previously known only from fragmentary specimens. This edited volume provides the taphonomy and paleoecology of the partial skeleton, as well as detailed comparative descriptions of the preserved elements of KSD-VP-1/1 and their implications for our understanding of early hominin paleobiology. This chapter will present a basic introduction to the discovery of KSD-VP-1/1 and provide a guide to the contents of the volume.

Acknowledgments

The Paleoanthropology Laboratory of the ARCCH made its laboratory and fossil storage space available to the Woranso-Mille project. The support from the curators in the laboratory is also very much appreciated. The excavation of KSD-VP-1/1 would not have been possible without the participation of the many field assistants from Addis Ababa and the Afar people at Waki and Waylateyta. I am grateful to all of the authors in this volume for their contribution to our understanding of Australopithecus anatomy, paleobiology and paleoenvironment , and to the many colleagues who have provided comments, advice, and discussion to the research conducted at Woranso-Mille in general and to the research presented in this volume specifically.
