Department of Paleobiology
The mission of the Department of Paleobiology is the discovery, description, and interpretation of the past history of life on Earth and its context within the surrounding environment. Research efforts of the Department are driven by important evolutionary and ecological questions that require the charting of the patterns and processes of past life. These endeavors are accomplished by active field work, examination of collections, archiving of re-sulting data, publication of research results, and sponsoring a variety of education and outreach activities.
The Department of Paleobiology is a center for interdisciplinary research on the history of the Earth and its biota, and their interactions through time. Research programs in paleontology encompass the systematics of specific fossil animal and plant groups and their associations, the evolutionary processes underlying phylogenetic pat-terns, paleoecology, the responses of ecosystems to abiotic and biotic change, and the relationships of ecological patterns to evolving lineages. Studies of envi-ronmental history emphasize the responses of shallow-water depo-sitional systems to changing climates and rates of subsid-ence, reef dynamics, and the history of ocean basins.
The Department of Paleobiology has responsibility for the day-to-day cu-ration of the National Collection of Fossils and Sediments. The Collection rep-resents a microcosm of the Museum’s biological departments and has a historic origin. Some of the specimens were collected even before the Powell and Hayden Surveys of the late 1800’s.
The Collection counts more than 42 million fossils including over 290,000 type specimens, and 50,000 sediment sam-ples with representative material collected within and outside the United States and spans geologic time from the Precambri-an to the Recent. To facilitate access, accountability, and curation, the Collection is divided into four sub-collections: invertebrates, vertebrates, plant fossils, and sedi-ment samples. There is a general organizational scheme used for most of the sub-collections. Published speci-mens are grouped by geologic age and taxon (e.g., Mesozoic Gastropoda Type, Paleozoic Anthozoa Type). Identified but unpublished specimens are stored either as a unit (e.g., Brachiopoda Biological Collection) or by geologic age and taxon (e.g., Mesozoic Gastropoda Biologic). Stratigraphic collections are organized by geologic age then locality. Although they contain a variety of taxa, some unique collections (e.g. Burgess Shale Types, Burgess Shale Biologics) are kept together as sub-collections. The collections also include outstanding archival documentation relating to collections and specimens such as illustrations, paintings, field notebooks, annotated maps, correspondence, photographs, specimen ledgers, and card files.
Each year, thousands of specimens are loaned to students and researchers around the world for scientific investigation as well as for exhibit. Specimens are added through staff collecting, donations from private individu-als and education-al/public institutions, and transfers from other government agencies.
The collections include outstanding invertebrate paleontology collections, including the Trilobite Type Collec-tion; Ha-zen Trilobite Collection; Cenozoic Marine Mollusk Type Collection; Burgess Shale Collection, totalling over 65,000 speci-mens and representing the largest collection of these fossils in the world; Echinodermata in-cluding the Springer Collection, donated by Frank Springer in 1911, is the largest repository of fossil crinoids in the world consisting of nearly 4,500 primary types, including 1,678 holotypes, mostly from Paleozoic sequences in North America and Europe as well as more than 100,000 secondary types derived from all parts of the world; Glass Mountain Collection (Brachiopoda); Green River Insect Collection; Foraminifera Collection which is the largest repository in the world of foraminiferal type specimens including over 16,000 primary types (holotypes and paratypes) and over 200,000 secondary types representing about 75% of all the type specimens of the American smaller foraminifera and 90% of the larger American Mesozoic and Cenozoic foraminifera and including the Cushman Collection of Foraminifera, willed to the Smithsonian by Dr. Joseph A Cushman, of approximately 150,000 mounted slides, 25,000 type slides and figured specimens; Solnhofen Collection; and the Micropaleonto-logical Reference Center Collection housing more than 10,000 microfossil samples of foraminifera in specimen containers, as well as calcareous nannofossils, radiolarians and diatoms on slides.

Outstanding collections include the Hagerman Horse Collection; Teleoceras Collection; Marsh Dinosaur Col-lection; and Fossil Marine Mammal Collection. Vertebrate collections of fish, amphibians, and reptiles are ar-ranged taxonomically; mammals are organized first by stage and then taxonomy. The first significant dinosaur fossils added to the museum’s collections was the type specimen of the sauropod Dystrophaeus viaemalae, col-lected by J. S. Newberry and donated in 1859, and the Lower Jurassic dinosaur footprints from the Connecticut Valley, donated in 1861. The collections currently include over 1,500 catalogued specimens of dinosaurs, 30 of which are on display. The Marsh Collection, the largest single dinosaur collection at the Smithsonian, includes some of the most important dinosaurs known to science including exhibit specimens of Allosaurus, Stegosaurus, Camptosaurus, Ceratosaurus, Triceratops, and Edmontosaurus.

The paleobotany type collection, considered among the best collections of its kind in the world, is arranged by publica-tion date and author whereas the rest of the paleobotany collections are organized by stratigraphy, collector, or age. The fossil plant collections are complemented by two collections of modern cleared and stained leaf samples of flowering plants, preserved on more than 20,000 glass slides, the best of their kind for comparison with fossil material.

The Sediment Collection includes a reference collection of over 50,000 sediment samples as well as repre-sentative ma-terial collected during historic cruises such as the Albatross and Coastal Survey Studies conducted in the late 1800’s. In addi-tion, cores collected from coral reefs to study their Holocene history include cores from Galeta Reef, Panama, Nonsuch Bay, Antigua, Stocking Island, Bahamas, and Holandes Cay, Panama. Also in-cluded are surface samples from Cobbler’s reef, Barbados, and stromatolite samples from both north Belize and Shark Bay, Australia. Contact: Kathy Hollis
Laboratories of the Department include the Paleontology Preparation Lab, Sedimentology Lab, Acid Room, and several specialized preparation areas for invertebrates and fossil plants. These laboratories are well equipped for paleontological, sedimentological, and marine geological research. The Department maintains a darkroom, facilities for preparation of thin sections, petrographic equipment, X-ray apparatus, and several facilities for bulk maceration of matrix-bound fossil specimens ranging from arthropod cuticles to vertebrate bones.
Active, on-going field research sites include the Western Interior of North America, and involves collections of paleo-botanical, vertebrate, and invertebrate fossils from Late Paleozoic to Neogene deposits. Departmental staff also have major field programs in Africa, including southern Africa, where Permian to Triassic strata are ex-amined for biotic turnover, eastern Africa, particularly the Pliocene to Recent record of hominids and co-occurring mammals in Kenya and the adjacent region, and the Nile Delta in northeastern Africa, where the sedimentological and human record of Dynastic to Roman Egypt is pre-served. The Department also is actively involved in re-search of coral reefs at Carrie Bow Cay in Belize, as well as sites across the major oceans where sediment cores are examined for microfossil and physical material to detect major environmental and biological events during the past 100 million years.
The Smithsonian Contributions to Paleobiology is a monographic series dedicated to the publication of ex-tensive systematic studies of fossil organisms. The Atoll Research Bulletin covers research on the biology, ecolo-gy, and environmental settings of present-day and fossil coral reefs. The Evolution of Terrestrial Ecosystems Newsletter informs colleagues of re-search, colloquia, and other events pertaining to the Evolution of Terrestrial Ecosystems consortium at the NMNH. The Fos-sil Record is the quarterly Department newsletter and includes narrative updates of departmental activities and research.
Education and Outreach
The Department of Paleobiology organizes and participates in a variety of public outreach programs, both formally and informally. The most popular educational program is the Paleobiology Training Program, which con-sists of classes plus field trips covering an introduction to geology and paleontology and an overview of current departmental research. The FossiLab is a glass enclosed laboratory in the paleontology exhibits space where trained volunteers prepare fossils for scientific study, display, or storage, and speak with the public about their work. Through a variety of cooperative arrangements staff members act both formally and informally as advisors to graduate students and occasionally teach courses at universities both locally and nationally. Specimens are made available to students for thesis work through loans to their academic advisors and students and researchers are welcome to visit the collections and facilities to conduct their investigations on-site.
The Department of Paleobiology maintains 7 libraries. For some, oversight is jointly shared with the Smith-sonian Insti-tution Libraries (Kellogg, Vertebrate Paleontology, Cooper). For others (Todd, Paleobotany, Coral, Brachiopod) the respon-sibility for care and maintenance rests solely with Paleobiology staff. The libraries contain books of general interest to geology and paleontology, as well as volumes specific to the taxonomic focus. The Department houses a complete set of the Deep Sea Drilling Project-Ocean Drilling Program publications in the Micropaleontological Reference Center.
The Vertebrate Paleontology library collection holds over 1,800 volumes focusing on physical geography, stratig-raphy and systematic paleontology and paleozoology of chordates and vertebrates of the Paleozoic, Mesozoic, Tertiary, and Qua-ternary periods. The Cooper Reading Room contains about 250 volumes on general geology, invertebrate paleobiology, his-torical geology, paleontology and other subjects.
The Remington Kellogg Library of Marine Mammalogy contains about 1,800 books and bound journals on all aspects of fossil and living marine mammals, including paleontology, morphology and phylogeny.
Programs and Partnerships
The Evolution of Terrestrial Ecosystems Program
The Evolution of Terrestrial Ecosystems Program (ETE) is an interdisciplinary program whose mission is to document and interpret the history of terrestrial ecosystems from 420 million years ago to the present and to syn-ergize interactions be-tween paleoecologists and ecologists. ETE brings together scientists from around the world to study the patterns and causal process of animal and plant community assembly and disassembly over geologi-cal time and up to the present day. Infor-mation from the fossil and geological record provides a unique perspec-tive on ecological change through comparisons of past ecosystems with those of today and helps us to understand how ecosystems could change in the future.
