NAME THAT FOSSIL:

This fossil forms when sediments bury an organism and the sediments change into rock. Then, the organism decays leaving a cavity (hollow area) in the shape of the organism.

• mold fossil

• cast fossil

• preserved fossil

• trace fossils

NAME THAT FOSSIL:

This fossil forms when the mud or sand hardens to stone where evidence of an organism is left behind such as footprints, coprolites (feces), egg shells, gastroliths (stomach stones), regurgitaliths (vomit), nests, trails, burrows, etc...)

NAME THAT FOSSIL:

This fossil forms when organisms are pressed between layers of soft mud or clay that hardens squeezing almost all the decaying organism away leaving the carbon imprint in the rock.
