Plato

Smith
Certain fossils always in same layer rock, diff organisms lived in diff parts of time
Lamarck
Simple forme changed to more complex
Aristotle
Great chain of being

Darwin
Theory of evolution by natural selection
Malthus
Wrote essay that started Darwin’s natural selection theory
Buffon
Species originated in more than one place and modified over time
Wallace
arrived at natural selection theory by himself
Unaltered remains
Encrustation, amber entombment, refrigeration
Encrustation
Dissolved minerals form thin crust over (after dissolve we get orignal material)
Amber entombment
Insect trapped in pine resin harden into amber (we get dna sample)
Refrigeration
During ice age, animals trapped in ice (lots of cellular material)
Altered remains
Permineralization; replacement, recrystallization, carbonization
Permineralization
Pores in bones, shells become filled with mineral deposits (general structure, good detail)
Permineralization
Pores in bones, shells become filled with mineral deposits (general structure, good detail)
Permineralization
Pores in bones, shells become filled with mineral deposits (general structure, good detail)
Recrystalization
Original composition change to crystal (great detail)
Carbonization
Under pressure liquid/gas is forced out leaving film of carbon (only outside surface detail)
Trace fossils
Animal tracks, gastroliths, coprolites
Animal tracks
Footprints (calculate stride/how anima moves)
Gastroliths
Herbivores matter in stomach, snooty polished stone (what they ate)
Coprolites
Fossil poops (bones of prey, seeds, plants)
