What are fossils?. FOSSILS. . are. . the . preserved remains or . traces.  of animals, plants, and other organisms . that lived long ago.. When an organism dies, hard parts of the animal (bones, teeth, shells, etc.) can be preserved in rock.. Phylogenies. The process of evolution produces a pattern of relationships between species. . As . lineages evolve and split and modifications are inherited, their evolutionary paths diverge. . This . Remains . of once living organisms.. Form from decay and are buried by sediment.. Sediment hardens into rock and preserves the shape of the organisms.. Fossils. Fossils . Remains. Molds. . Casts. . Fossils can tell us about our biological (life) past…. We’d have to build stronger refrigerators.. FOSSILS can tell us about our. B. IOLOGICAL PAST.. How can fossils help tell us Earth’s . GEOLOGIC. 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.. Chapter 25 Opening Roadmap. .. © 2017 Pearson Education, Inc.. Introduction. Biologists must consider profound change in the nature of life on Earth over vast periods of time. Biologists use two major analytical tools to reconstruct the history of life:. 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.. Fossils have helped determine approximately when life first appeared, when plants and animals arrived on land, and when organisms became extinct.. CONDITIONS NEEDED FOR FOSSIL FORMATION. Whether or not a dead organism becomes a fossil depends upon how well it is protected from scavengers and agents of physical destruction, such as waves and currents.. Fall 2012. Training Presentation. IA. Introduction. Tell Students:. The . Geologic Time Scale . covers Earth’s entire history. It is divided into 4 major time intervals called eons. The eons are not the same length, but are based on major events. SCHEDULE. GROUP . A 12/3/18 . ASHTON CALHOUN. EMMANUEL MARIN. HANNAH REEVES. GROUP B 12/5/18 . CAROLINE GRACE EARLE. ANDREW CALLAWAY.
