An intrusion is a body of igneous rock formed within Earth’s crust. When two features intersect, the one that cuts through the other is younger. This is known as the law of crosscutting relationships. Some strata contain index fossils, or fossils associated with a specific time in Earth’s history. If the same index fossil is found in ...Like Petoskey stones, honeycomb coral is a unique-looking sedimentary rock that is basically a fossilized favosite. Favosites are ancient types of coral that were made up of closely packed corallites. Honeycomb coral can be found on the shores of Lake Erie, however, like Petoskey stones, changing ocean patterns can transport this rock anywhere!Where did they live? Today’s stony (scleractinian) corals can be found in shallow or deep water, but most species live in warm, clear, tropical seas. They are important reef builders. All of the geological evidence shows that the extinct rugose and tabulate corals also preferred shallow, tropical environments. When did they live?Prehistory Isotelus..

Corals are cnidarians that live as polyps attached to the sea floor. Polyps of modern stony (scleractinian) corals produce a hard skeleton that is easily fossilized. Extinct rugose and tabulate corals also had hard skeletons and are commonly found as fossils. The scleractinian corals are probably descendants of the rugose corals. Fossils are excavated from many environments, including ancient riverbeds and lakes, caves, volcanic ash falls, and tar pits. Fossils are classified as either body fossils or trace fossils. Body fossils were parts of the organism, such as bones or teeth. Trace fossils are all other types of fossils, including foot impressions, burrows, and dung.Fossils are the preserved remains of deceased animals in rock.
