What’s a fossil?
Fossils show us clues about ancient life on earth from the biggest dinosaurs to the tiniest specks of pollen. Most prehistoric remains became preserved when layers of sand and mud buried them. The parts of the plant or animal that didn’t decay or break apart changed to stone over millions of years in a process called fossilization. Minerals seeped into the fossil replacing the organic matter and creating a replica in stone.
How do I find a fossil?
At the posted coordinates you will find a sign that talks about some of the fossils found in this area. One of the more interesting fossils in the area are Ammonites. Ammonites are known as index fossils. The presence or absence of these types of fossils help scientists age the formations.
How do I log this cache?
Look around the area near the sign you should see many fossils in the rocks - about 20 ft down the trail towards the lake you will find two large rocks on either side of the trail. Each rock has many fossils embedded in the limestone. To log this cache answer the following questions:
- What type of habitat was this when these fossils were formed? (e.g., forest, mountains, oceans, etc.)
- What type of rock are the fossile found in? (e.g., sedimentary, metamorphic or igneous?)
- Why does this type of rock often have fossils?
- In the rocks around you what type of fossils do you see?
