Laetoli: A Pliocene Site in Northern Tanzania.

This work presents the results of intensive fieldwork carried out from 1974 to 1981 at the site of one of the richest fossil sites yet discovered in Africa. In addition to hominid fossils, the remains of a large number of other vertebrate species have been collected. The vertebrate faunas from Laetoli are of special interest because of the differences in composition from other East African faunas of comparable age. Invertebrate fossils include terrestrial gastropods, the ova of solitary Hymenoptera, and some superbly preserved termitaries. This volume also details for the first time accumulated findings from the remarkable Footprint Tuff, a volcanic ash deposit in which are preserved the tracks and trails of a great variety of animals, many long extinct.
