What was going on in Utah 500 million years ago? Quite a bit, and this website provides an excellent overview of the diverse Cambrian life that flourished in an ancient sea that covered what is now the Beehive State. Interestingly enough, the website was created by the division of invertebrate paleontology at the University of Kansas Natural History Museum, and it includes images of a wide array of fossilized materials from this period of geological history. On the left-hand side of the page, visitors will find four primary sections, including "Localities and Geology" and "Online Fossil Exhibits and Collections". The "Localities and Geology" area is a good place to start as it gives an overview (complete with aerial photographs and maps) of the Cambrian period in Utah. The "Online Fossil Exhibits and Collections" area features fossil representative images from groups like mollusks, algae, jellyfish, and lobopods.
