Describes the rapid expansion of archeological geology, especially in the area of archeological excavations, where geologists use dating techniques and knowledge of geological events to interpret archeological sites. (MLH)

Discusses discoveries made during 1976 in various areas of invertebrate paleontology. (MLH)

Describes discoveries made in 1976 in areas of vertebrate paleontology, including research indicating that dinosaurs were warm-blooded. (MLH)

Antarctic drilling and mapping projects are reported on. (BB)

Geologists in this field are becoming increasingly involved in studies of land use. (Author/BB)

A brief summary of work completed by micropaleontologists in 1978. (BB)

Contributions to this field for 1978 are discussed. Of special interest are the jawless marine fishes that were found in marine deposits from Late Cambrian time. (BB)

Drilling during 1978 focused on three major geologic problems: the nature and origin of the oceanic crust, the nature and geologic history of the active continental margins, and the oceanic paleoenvironment. (Author/BB)

Research efforts tended to focus on the ancestry of major groups in 1978, and in particular on Cambrian fossils. (Author/BB)

Indicating that, although no broad conceptual notions in invertebrate paleontology were proposed during 1982, a large number of excellent papers focusing on testing, modifying, and documenting earlier speculations were published or presented at professional meetings. Highlights of papers, conferences, and research studies are provided (including…

A brief summary of the year's activity. (BB)

Highlights major activities, conferences, conference and published papers, monographs, and research studies in paleobotany during 1982. Indicates that paleobotanists made more frequent use of the perspectives and ideas of disciplines as developmental biology and sedimentology in their research endeavors. (Author/JN)

Reviews the work done by American scientists in archeological geology throughout the world in 1977. Summarizes studies in Greece, Israe, Egypt, and the United States. (MA)

Three major breakthroughs in Antarctic earth sciences which occurred during 1982 are discussed (finding of land fossils, meteorite, and subsurface microorganisms). Highlights of conferences, research activities, and significant publications are also discussed. (JN)

Early land plants and their ancestry remained an important, controversial issue in paleobotany this past year. Current research and theories on the subject are reviewed. (MA)
