A GUIDE TO THE ORDERS OF TRILOBITES Here it is! All things small, old, and anthropod! Ain't the web great!



And I quote:

" You'll learn about trilobite body parts, how scientists classify trilobites, when, where, and how they lived, and how to tell the major groups apart. You'll also learn where to turn for more trilobite information on the web and in the literature. I hope in the end you come to better appreciate their amazing variety. Although they are all extinct now, they represent among the first explosions of biological diversity that this amazing planet of ours has generated over the eons"
