  1. DISCOVERING FOSSILS By- Caitlin Tencate, Maggie Hermanson and Kelley Shomaker

  2. Background Information • Fossils - literally "having been dug up" are the preserved remains or traces of animals, plants, and other organisms from the remote past. • Fossils are used to : • 1. Reconstruct what the earth was like in the distant past • 2. To show how life has changed through time • 3. To correlate rock from one area to another to aid in searching for fossil fuels and minerals. • In Ohio, fossils can be found at: • Found in Fossil Park Sylvania • Caesar Creek Emergency Spillway • Hueston Woods State Park • A few other popular Cincinnati and Dayton locations. • Ordovician time period

  3. Coral a.k.a. Gummy Worms • Corals : • Simple animals that conceal skeletons made of calcium carbonate. • Corals can be either colonial or solitary. • Corals live attached to the seafloor and feed by trapping small animals with their tentacles.

  4. Bryozoans aka Gummy Bears • Bryozoans: • “Moss animals” are aquatic organisms that build stony skeletons of calcium carbonate. • Fossils found in rocks beginning in the Early Ordovician as a part of Ordovician radiation.

  5. Sour Gummy Worms aka Cephalopods • Cephalopods • Cephalopods means “head foot” • Fossil cephalopods were important parts of the marine food web

  6. Gummy Cherries aka Brachiopods • Brachiopods • Marine animals who are filter feeders who collect food particles. • Fossil shells from animals that lived in ancient seas. • Kentucky’s state fossil

  7. Gummy Tarantula aka Clams • Clams • Called bivalves because their shell is composed of two valves. • Found in marine and freshwater environments. • Filter feeder

  8. Sour Lightning Bugs aka Trilobites • Trilobites or Isotelus: • Trilobite means “three-lobed creature” • Marine organism, invertebrate creature that has hard outer shell or skeleton. • Ohio’s state fossil • Between 430 and 480 million years ago an ocean covered much of what is now Ohio.
