Dinosaur Tracks and Trace Fossils

• An Overview of Dinosaur Tracking. Glen G. Kuban. Good summary of the ways in which dinosaur tracks are formed, the major types of tracks (including a diagram that matches types of dinosaurs to types of tracks), and the types of information that can be obtained from studying tracks.
• Dinosaur Trace Fossils. Anthony J. Martin, Emory University. Describes different types of trace fossils (not bones) left by dinosaurs including tracks, nests, eggs, tooth marks, gastroliths (stomach stones), and coprolites (feces). Many images and short, easy-to-understand descriptions.
• Dinosaur trace fossil links provides links for more information about dinosaur tracks and traces.
• Dinosaur Footprints and Trackways from the Northeastern U.S. Digsfossils.com.  This site includes a geologic time chart showing the known locations of Triassic and Jurassic dinosaur trackways in the northeastern United States. You can click on the names to see pictures of the tracks. 
• A King-sized Theropod Coprolite found in Saskatchewan. K. Chin and others, U.S. Geological Survey. Interesting, online technical reprint from the journal Nature of large theropod (probably T-rex ) feces containing bones, which is direct fossil evidence for carnivory (meat-eating).
• Dinosaur Tracks. ScienceViews.com. This site tells the story of a Jurassic dinosaur trackway discovery in Utah.  Large theropod tracks are believed to be from Dilophosaurus .  Many pictures, including images of partial tracks believed to represent swimming dinosaurs.  Some images are in 3-D if you have 3-D glasses.
• Coal Mines as Localities for Studying Dinosaur Trace Fossils. Lee R. Parker and John K. Balsley. Interesting, online technical reprint describing dinosaur footprints found in western U.S. coal mines.
• From Stride to Leg Length to Speed. Maryann Buehler and Amy Quillen. Activity aimed at high school students in which data on dinosaur footprints are provided and students use calculations to interpret stride and speed.
• Creating Dinosaurs from Tracks. StudyWorks!Online. Short activity that uses ratios to determine speed of a Dilophosaurus from its footprints.
• Dinosaur Speed Calculator. Sorby Geology Group, University of Sheffield, England. Online calculator lets you estimate the speed at which dinosaurs were moving based on their tracks. You input a foot length, stride length, and choose from among several conversion factors. An explanation of the conversion factors is provided.
