Research Focus:

Terry Harrison is a biological anthropologist specializing in primate and human paleontology, evolutionary morphology, and paleoecology. His broader research interests include the systematics and evolutionary history of hominoids and cercopithecoids, comparative anatomy and functional morphology of primates, paleobiology, allometry, vertebrate paleontology, evolutionary theory, taphonomy, paleoecology and zooarchaeology.

His recent research has focused on the evolution and paleobiology of the Miocene and Pliocene hominoids from Africa and Eurasia, including the earliest hominins. Ongoing collaborative projects include: Miocene fossil hominoids from China, particularly Lufengpithecus from the late Miocene of Yunnan; the vertebral column of Proconsul from the early Miocene of East Africa; the paleobiology and systematics of fossil hominoids from the Miocene of Africa; late Miocene cercopithecids from the Siwalik Hills of Indo-Pakistan; taxonomic revision of Miocene East African lorisoids; the impact of global and regional climatic change, island biogeography, and human subsistence activities on the mammalian community of Borneo over the past 40,000 years; and the paleontology and geology of the Eocene locality of Mahenge in north-central Tanzania.

He has extensive paleontological fieldwork experience in Europe, East Africa, and Asia, and he is currently directing a major field program at the mid-Pliocene locality of Laetoli in Tanzania. Research on new fossil hominin finds from Laetoli, as well as analyses of the associated fauna and flora are currently underway. He is just beginning to develop new programs of field research at late Miocene to Pliocene localities in China and Egypt.
