Pennsylvania State Fossil Famous creation scientist, Ken Ham, refers to fossils as “billions of dead things buried in rock layers all over the world.” The chapter of Genesis in the Bible refers to a flood that covered the earth. The fossils found all over the world are evidence of this flood. The flood water carried dead animals and deposited them everywhere. When the waters receded, the remaining sediment buried the creatures’ bodies wherever they had settled. As the sediment dried, the dead creatures became fossilized. Among those creatures, great and small, was the marine arthropod called a trilobite. A trilobite, like all arthropods, had a segmented body, jointed legs, and an exoskeleton. Its external skeleton did not grow, so it had to be shed regularly for the trilobite to grow larger. The Phacops rana, a species of trilobite with large eyes, grew to be six-inches long and could roll up into a ball like a pill bug to protect itself from danger. The Phacops rana, now extinct, is
still memorialized by the multitude of fossilized remains, especially in State Fossil Review 1. Why was the Phacops rana chosen to be the state fossil? 2. What are some characteristics of a Phacops rana? |
