Document Summary
Key to the identification of major groups of organisms preserved as fossils. Fossil large enough to examine with the naked eye. Fossil very tiny, barely visible to naked eye or microscopic, typically less than 1 mm in greatest dimension. Fossil appears to be track, trail, burrow, or footprint with no indication of the remains of the organism. Fossil represents some of the physical remains of the organism or an impression of those remains. Fossil remains are twigs, leaves, or wood, commonly black or dark brown. Fossil remains are seashells, bones, or teeth; typically light colored, but may be blue gray to black. Fossil remains are pieces of bone, teeth, or scales; commonly white, bluish gray, or yellowish brown, may be black. Fossils are seashells or skeletal remains of various shapes; may be composed of one or many parts. Fossil has weakly developed skeletal structure, tiny hair like or needlelike pieces, or numerous layers.
