Paradoxides - Species Profile

 Paradoxides - Species Profile will be the topic of discussion on Natures Talk Shows Fine Art of Paleontology. Paradoxides is a large trilobite close to half a meter (one and a half feet) long. There are many species and subspecies of this genus and they have been collected from the Czech Republic, Scandinavia, Wales, Spain, Morocco, Newfoundland, New Brunswick, Maine and Massachusetts. Geologists use these species to correlate rock formations from these different areas. This strange geographic distribution and the remarkable similarities of some trilobites from North America and Europe puzzled paleontologists.During the Cambrian Period, 510 million years ago, before there were any lobsters these trilobites crawled along the seafloor, but not off the coast of North America or Europe. They lived in the shallow waters off the coast of a small continent that no longer exists called Avalonia by geologists.
