Molds and Casts. Carbon Films. Preserved Remains. Trace Fossils. Petrified Fossils - . How do they form?. Mineral rich water soaks into cracks and crevices. Minerals “precipitate” and fill the spaces. . Fossils are the . preserved remains . or traces of . living. things. Most fossils form when . living. things die and are buried by . sediments. . The . sediments. slowly harden into . rock. Fossils. and. Unconformities. The Geologic Cycle. 3 key events: deposition, uplift, erosion. Sedimentation of beds A-D beneath the sea. Uplift above sea level and exposure of D to erosion. Continual erosion strips D away completely and exposes C to erosion. Can you name any dinosaurs?. Do you know what they looked like or how they moved?. Scientists have been able to tell us many things about organisms (such as dinosaurs) that lived millions of years ago.. Fall 2012.
