The Thyreophora are a group of small to quite large armored plant-eating dinosaurs. The most familiar are Stegosaurus and Ankylosaurus, though there were many others. The two earliest known, Scutellosaurus and Scelidosaurus along with the remaining two major groups Stegosauria and Ankylosauria are described on this site. Full description.

This site describes sabretooth animals of the Cenozoic Era. The sabretooth morphology has appeared several times during the history of mammals. Sabre-toothed members of the Carnivora appeared independently at least twice. Sabre teeth evolved both among the true cats, or the family Felidae (these sabre-toothed cats are sometimes classified in a separate subfamily of cats, the Machairodontinae) and ... Full description.

Evidence presented on this site is overwhelmingly in favor of birds being the descendants of a maniraptoran dinosaur, probably something similar (but not identical) to a small dromaeosaur. Dr. Jacques Gauthier created the first well-accepted, detailed phylogeny of the diapsids. His work provided strong, compelling support for the theory that birds are theropod dinosaurs. The development of the theory ... Full description.

This lesson uses the 3.6 million year old tracks of early hominids in Laetoli to provide a tantalizing opportunity to explore how scientists use patterns of the present to understand the past. What do those footprints tell us? How can we find out? Students measure and correlate their foot lengths and body heights, then use this data to estimate the height of Laetoli hominids.

In this lesson, students read and discuss selected and edited excerpts from the essays of Stephen Jay Gould on the subject of contrivances. Students learn that many features of modern organisms reflect the structure of their ancestors in ways that are not adaptive. They also learn that one of the best indicators of evolution is not the examples of perfect adaptations, but of the relatively imperfect ... Full description.

In this lesson about speciation and its role in evolution, different subspecies of a California salamander are placed on a grid map of California according to where samples were collected. Discussion focuses on patterns of their distribution, their likely evolutionary relationships, and probable sequence of formation from the original form (speciation). Full description.

This on-line project is part of the Center for Improved Engineering and Science Education (CIESE) program. As they complete this series of lessons, students will use real-time data to solve a problem, study the correlation between earthquakes and tectonic plates, and determine whether or not there is a relationship between volcanoes and plate boundaries. Musical Plates has four Core Activities that ... Full description.

This series of activities is designed to show students how a large scale planetary process, the transport of heat over the surface of the Earth, operates and has operated over time. The activities include how energy is absorbed by the Earth from the Sun, how and why this energy is distributed over the earth's surface, what controls energy distribution, how we can track the energy distributing process ...
