The Geological, Isotopic, Botanical, Invertebrate, and Lower Vertebrate Surroundings of Ardipithecus ramidus

摘要

Ardipithecus ramidus was found in exposed sed-iments flanking the Awash River, Ethiopia. The local geology and associated fossils provide critical information about its age and habitat.rnMost of Africa's surface is nondepositional and/or covered by forests. This explains why so many discoveries related to early hominid evolution have been made within eastern Africa's relatively dry, narrow, active rift system.
