More Paleozoic Fsils

In this second book on Paleozoic fossils, over 840 all new specimens from this period are provided, organized by biologic (taxonomic) position. It is a real eye candy feast for fossil enthusiasts. Come and explore the fossil evidence for a world that was ancient and long gone when the dinosaurs ruled the earth. Discover the sponges, archaeocyathids (reef builders), cnidaria, worms, brachiopods, bryozoans, mollusks, arthropods, echinoderms, and chordates that populated the oceans and inhabited the land from 535 to 235 million years ago. Much of the fossil record for this era reveals marine organisms in many forms, but this is also the period when clear evidence for plants and animals appears in hard rock. While the earth presents many natural barriers to the collecting of Paleozoic fossils, the author has overcome those barriers to present readers with a formidable collection.
