3rd Fossils

What is a fossil? A fossil is preserved remains of a plant or animal that lived long ago.
What is amber? Amber is hardened tree sap.
What does a Paleontologist study? A Paleontologist is a Scientist that studies fossils and organisms that lived long ago.
What is a hollow space in the shape of a dead plant or animal called? It is called mold.
What is it called when a fossil is formed in a mold when minerals, sand and mud fill in spaces? It is a cast.
What are fossil fuels? Fossil fuels are sources of energy formed from the remains of plants and animals.
How do you define trace or imprint? Trace or imprint is defined as shallow print or mark in solid rock (often a footprint or leaf print).
What type of rock often has fossils? Sedimentary rock often has fossils.
When the actual plant or animal is completely preserved in amber, ice or tar it is called what? It is a true-form fossil.
What does it mean to decay? Decay means to rot away - the soft parts of an animal do this
Hard body part fossils such as bones/teeth = minerals seep into the small holes and harden
What does petrified mean? Minerals seep into the small holes in wood and harden: example is petrified forest
What are the steps for a plant or animal to become a fossil? 1. The plant or animal dies. 2. It is covered in dirt, soil or sediments. 3. The soft parts decay. The hard parts remain. 4.Minerals seep into the tiny holes causing it to harden.
Fossil Fuel Facts: Fossils fuels are coal, natural gas and oil. We may run out of them in the future because they are non-renewable ( limited supply).
Fossils are usually found in Sedimentary rock.
Dinosaurs lived approximately 65 million years ago.
Fossils will not help us learn about an animal`s color.
Not all animals/plants become fossils. They are actually quite rare. Plants/animals have the best chance of becoming a fossil if they are buried deeply in the ground.
Small bugs and insects are most likely to be trapped in amber.
Only the hard parts of plants and animals become fossils because the soft parts decay.
We only know about dinosaurs because of their fossils. No one was alive with the dinosaurs.
Students should be able to describe the difference between a mold and a cast fossil.
