I know you made these for an introductory college course - but as a rockhound, I am loving the information! Thanks for making such informative videos...

CLARIFICATION: There is an error in this video. Coprolites should have been listed in the category of indirect fossils. Direct fossils include left-behind parts of organisms, such as bones, shells, and teeth or imprints of the organism left behind such as carbonization, molds, and casts. Indirect evidence is information about how ancient life lived: footprints, eggs/nests, burrows, tooth marks, gastroliths (stomach bones), and coprolites (dung)
