from Wikipedia, the free encyclopedia

David John Bottjer (born October 3, 1951 in New York City , New York ) is an American paleontologist . His research focus is evolutionary paleoecology .

Life

In 1973 Bottjer received his Bachelor of Science from Haverford College . In 1976 he graduated with a Master of Arts from Binghamton University , Binghamton , New York . In 1978 he was with the dissertation Paleoecology, ichnology, and depositional environments of Upper Cretaceous chalks (Annona formation; chalk member of Saratoga Formation), Arkansas southwestern at the Indiana University for Ph.D. PhD. From 1978 to 1979 he was a member of the National Research Council of the United States Geological Survey . In 1979 he was a research fellow at the Natural History Museum of Los Angeles County . From 1979 to 1991 he was assistant professor and then associate professor in the Department of Earth Sciences at the University of Southern California . In 1986 he worked as a visiting scholar at the Field Museum of Natural History in Chicago . From 1989 to 1996 he was editor of the journal Palaios of the Society for Sedimentary Geology . Since 1990 he has been co-editor of the book series Critical Moments and Perspectives in Paleobiology and Earth History at Columbia University Press . Since 1991 he has been chairman of the Department of Earth Sciences at the University of Southern California. In 2000 he was President-Elect for the Pacific Coast Division of the Society for Sedimentary Geology. Since 2000 he has been editor-in-chief of the journal Palaeogeography, Palaeoclimatology, Palaeoecology at the Elsevier publishing house . Since 2003 he has been a professor in the Department of Biology at the University of Southern California. Bottjer is a member of the Society for Sedimentary Geology, the Paleontological Society , where he was President from 2005 to 2007, the Geological Society of America , the American Association for the Advancement of Science , the International Paleontological Association, the Paleontological Research Institution and in the Geological Society of London .

Bottjer's work focuses on paleoecological and paleobiological tendencies in marine multicellular organisms during the Phanerozoic , on bioturbation in marine sedimentation environments, and on stratigraphy and paleoenvironments of sedimentary rocks .

In 1986 Bottjer and Mary L. Droser set up the trace structure index (Ichnofabric index). This method quantifies the levels of bioturbation in the sedimentary rock. It is a classification of the amount of trace fossil activity on a scale from 1 to 6. A value of 1 means the complete absence of bioturbation, while the highest level contains a layer area of ​​over 60 percent trace fossils.

In 2006, Bottjer took part in the documentary Flock of Dodos: The Evolution-Intelligent Design Circus by Randy Olson.

Awards

In 1999 he was elected a Fellow of the American Association for the Advancement of Science . In 2014 David Bottjer received the Raymond C. Moore Medal for Paleontology from the Society for Sedimentary Geology and in 2019 the Paleontological Society Medal .
