LEARN MORE ABOUT DINOSAUR TRACE FOSSILS 
ON-LINE

If all of the dinosaur bones in the world disappeared 
tomorrow, paleontologists still would have plenty of evidence 
for the existence of dinosaurs through dinosaur trace fossils. 
Explore these fossils at the Dinosaur Trace Fossil Web Site. 
A trace fossil is indirect evidence of ancient life (exclusive of 
body parts) that reflects some sort of behavior by the 
organism. Examples of trace fossils are tracks, trails, 
burrows, borings, gnawings, eggs, nests, gizzard stones, 
and dung. In contrast, a body fossil is direct evidence of 
ancient life that involves some body part of the organism.

A COMPLETE LISTING OF ALL KNOWN DINOSAUR 
GENERA

A list of over 800 dinosaur genera can be found at the 
Dinosaur Genera web site. This list includes all known 
dinosaurs plus a few (perhaps closely related) non-dinosaur 
species which are often confused for dinosaurs. Along with 
the species name it includes the reference to where that 
species was first described.

EXPLORE THE PALEO RING

The Paleo Ring is a newly developing collection of websites 
and pages that are devoted primarily to the promotion of 
paleontology, paleoanthropology, prehistoric archaeology, 
the evolution of behavior, and evolutionary biology in 
general. It is designed to facilitate the enjoyment of those 
interested in the history of life on this planet, including the 
development of our own species, by providing a variety of 
sites with minimal effort and searching. At the same time, 
members of The Paleo Ring can enjoy more exposure for 
their website.

Go to http://www.pitt.edu/~mattf/PaleoRing.html to explore 
the listed topics.
