Our department features research and graduate education in micropaleontology and vertebrate paleontology. We study some of the largest and some of the smallest creatures that were routinely fossilized during the Mesozoic and Cenozoic.
Our unique mix of specialties provides the means to examine ancient ecosystems from the heights of the mountains to the depths of the oceans, and from the equator to the poles.
Our students use these fossils to examine problems in taxonomy, biostratigraphy, evolution, paleoclimate, and paleoceanography. There is a large variety of paleontology courses taught on a regular basis, including courses on specific fossil groups. There are also many courses on topics related to paleontology. Students have access to the vast fossil and sample collections of the University of Nebraska State Museum and the UNL Ocean Drilling Program Micropaleontological Reference Center. Many of our students also find it handy to have a valid passport, since they may end up traveling to Antarctica, sailing on a research drilling vessel, participating in the Schramm field course, or doing field work in exotic places.
Diatoms in continental ecosystems - Sheri Fritz and her students use diatoms from lake deposits to examine questions of environmental change during the Quaternary. The Fritz Lab has on-going work on the paleoclimatic history of the Great Plains, Rocky Mountains, and tropical South America.
Calcareous nannoplankton in marine ecosystems - David Watkins and his students use calcareous nannofossils (coccoliths) from marine sediments to examine questions of evolution, biostratigraphy, and paleoceanography during the Mesozoic and Cenozoic. The Watkins Lab has on-going work on quantitative biostratigraphy of Cenozoic sequences in the Gulf of Mexico and the Pyrenees, and the Upper Cretaceous of the Western Interior Basin (USA), as well as Late Cretaceous paleoceanography from the Atlantic.
Diatoms in marine ecosystems - David Harwood and his students use diatoms from marine sediments to examine questions of evolution, biostratigraphy, and paleoclimatic change during the Late Cretaceous and Cenozoic. Much of the on-going work of the Harwood Lab centers around the diatomaceous sediments recovered from the coastal sediments of McMurdo Sound, Antarctica, by the ANDRILL Program.
Cenozoic mammals and isotopes - Ross Secord and his students use mammalian fossils and stable isotope geochemistry to examine how climate change drives faunal and environmental change. Stable isotopes in mammal teeth and contextual minerals provides information about the paleoclimate and paleoenvironment in which the mammals evolved. There are a number of times during the Cenozoic when faunal turnover or mammalian dispersal events appear to be correlated to climate change. The Secord Lab has on-going projects on climate and evolutionary events in the Paleogene of the Big Horn Basin.
UNL Fossil Collections
The Ocean Drilling Program Micropaleontological Reference Collection housed at UNL contains marine diatom and calcareous nannofossil samples from all of the world's ocean basins. The collection spans the upper Triassic through Holocene. The department also houses the H.V. Andersen Foraminiferal Reference Collection.
The University of Nebraska State Museum contains a collection of more than one million numbered specimens. The collection is dominated by Cenozoic mammals from the Great Plains, and also includes significant collections of Paleozoic fishes, Mesozoic marine reptiles, and Cenozoic lower vertebrates.
