Activity provides students an opportunity to make a stratigraphy cup.

After a study of the principle of original horizontality and the law of superposition, and how to determine the ages of rock layers and how they are formed, learners go on a field study to observe and gather information about rock...

The Museum of Paleontology at Berkeley offers an online geological time machine which allows you to catch a glimpse of ancient eras in earth's history. Click into an "Era" to learn about its stratigraphy, life forms, localities, and...

The discipline of stratigraphy looks at the order and relative position of strata and their relationship to the geological timescale. This chart shows the strata of Indiana from the Pre-Cambrian to the Pennsylvanian Periods.

Activities for the classroom that teach about stratigraphy and seriation, two methods used in the relative dating of objects in archaeology.

A brief overview of the Triassic Period, along with links to more detailed information on its subdivisions and life forms. Also includes information about subdivisions of the Period, along with Stratigraphy, Localities, and Tectonics.

A geology field investigation where students investigate fossiliferous limestone, the study local stratigraphy, and understand how glaciers and rivers have shaped the community.

The major goal is to correlate the lithology and geologic setting to unraveling the geologic history. Individual excursions center upon the local stratigraphy, features of glacial origin, evidence of Cameron's line, features of Croton...

[Free Registration/Login may be required to access all resource tools.] Looks at how stratigraphy can be used to determine the relative ages of rocks, how unconformities occur, ways to match rock layers in different areas, and how...

This site contains a chart showing the progression of the Paleozoic Era. Each section of the chart leads to information about the geological, biological, and climatic elements of a specific period of the era.

Access, from one index page, to three-dimensional photographs of all U.S. national parks. Standard photographic images and tours and selected geological resources (e.g., stratigraphic maps) for each park can also be linked to from this...

A fascinating exhibition on early Mesopotamia which looks at the city of Ur located in Sumer, which is now part of Iraq. It discusses the history of Ur and its excavation. Most of the exhibition talks about the Royal Cemetery of Ur,...

This article gives a detailed explanation of how transgression and regression of sea levels work to create deposits of sedimentary rocks. Illustrations show the layering that takes place over time. The article discusses how geologists...

This educational module enables students (5-12) to experience ongoing research of University of California paleontologists studying about life in Montana 60-70 million years ago. It gives students the opportunity to experience the...

An excellent overview of the Paleozoic Era. It also provides a chart where you can learn information regarding each of the time frames within the era.

What kind of evidence could demonstrate that humans have begun to dominate and alter the life systems of Earth and have entered a new geological epoch? This article discusses the suggestion that we have entered the Anthropocene and...

An overview of the Jurassic Period, including links to more detailed information about the geology and biological changes of the period.

Discussion of the Caribou Lake Complex in Manitoba as a major archaeological unit. It was a campsite for Paleo-Indian, Archaic, and Woodland cultures. Excellent graphic showing stratification of remains.

Seventeenth-century Danish geologist Nicolas Steno earned his chops at a young age, studying cadavers and drawing anatomic connections between species. Addison Anderson recounts Steno's little-known legacy and lauds his insistence on...

A resource highlighting the process of dating methods in archaeology. Look at Relative Dating and Absolute Dating systems.

This site provides information about the geologic relationships of rock layers, as well as much about geologic time and the history of Earth.

This site is provided for by the Malin Space Science Systems. Reprint of an article from the "Journal of Geophysical Research", a publication of the American Geophysical Union. Very detailed analysis of Magellan images. Includes...
