The Treatise project, founded in 1948 by the late Professor R. C. Moore, involves some 300 paleontologists worldwide and is one of the longest-running scientific enterprises in history, providing an invaluable resource for all aspects of invertebrate paleontology. Petroleum geology, stratigraphy, and paleontology. Current research includes integrated subsurface geology and geophysics, stratigraphy, petroleum geology, and conodont biostratigraphy. Current research includes biological anthropology, paleoanthropology, human osteology, and old world prehistory. Late Pleistocene New World archaeology.
Current research includes archaeology, hunters and gatherers, evolutionary ecology, and lithics.
