    Types of fossils Types of fossils Presentation Transcript

    • Types of Fossils Different kinds of fossils are created different ways!• Preserved organisms• Mineral replacement• Impression fossils
    • What is a preserved organism? • Fossils frozen in time • The soft body parts are preserved as well as the hard parts • Decay of the plant or animal is minimal How do we preserve things in our homes?
    • Preserved Organisms
    • Mineral Replacement• Hard parts of an animal decay slowly- like bones, and claws• when animal is buried water seeps through the ground, through the bone.• The seeping water dissolves the bone, and minerals in the water replace the bone one cell at a time.• This eventually becomes stone.
    • When mineral replacement occurs it isalso called petrification
    • Mineral ReplacementThe Utahraptor found at DaltonWells Quarry in east-central Utah,near Moab! The minerals that petrified this ammonite fossil are all different and make it different colors.
    • Impression Fossils• These fossils can show detailed outlines of organisms like thin plants or small animals, which die in sediment.• As they decay, they leave a carbon deposit that shows as a dark print of the organism• Impression fossils also include tracks
    • Impression Fossils Dinosaur footprint in sandstone found in UTAH! Trilobite Impression fossil. See how it is 3 dimensional? Can you tell the fossil is darker then the gray stone?
