BSc 4 th Semester Open Elective Fundamentals of Geology BOE OPEN ELECTIVE COURSE OTHER THAN GEOLOGY MAIN STUDENTS Dr Abdullah Khan Associate Professor Department of Geology AMU. layer of soil is made of clay and minerals and contains less humus (soil profile). 2. . _____. the oldest rock layer located (Earth’s story). 3.. _____. process moves sediment (erosion). 4. . _____ the number of years a fossil or rock layer has existed (absolute age). 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.. 1. Overview of Topics . Upon Death of Dinosaur. Changes in Bone Composition during Fossilization: Garland’s Categories. Organic Matter in Dinosaur Bones. Soft Tissue Preservation in Dinosaurs. 2. What is Taphonomy?. 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. OVERVIEW. Chapter 2. What is fossilization? . broad spectrum of views/ theoretical development. Key issues. global vs. local. product vs. process. Chapter 3. Putative behavioral reflexes of fossilization. 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.. 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. Evolution. A Swedish botanist in the 1700’s who developed a classification system for the organisms known at this time .
