What are the four general features of the fossil record?
The remains of a plant or animal are encased in sediment and it hardens into rock as the
remains of the plant or animal disentegrates. A hole is left in the rock in the shape of the
animal's remains. That is the mold. The mold will fill with sediment or magma and when it
hardens, it leaves a cast.
They think sediments are laid down slowly over millions of years Eventually conditions change
and the sediments harden to form rocks. The conditions in which the sediments were laid down
determine the type of sediment, which in turn determined the kind of rock formed.
Water with lots of minerals.
1. Fossils are usually found in sedimentary rock. Since most sedimentary rock is laid down by
water, it follows that most fossils were laid down by water. 2. Most of the fossil record is made
up of hard shell creatures like clams. Most of the rest are either water-dwelling creatures or
insects. Only a tiny fraction of fossils are plants, reptiles, birds, and mammals. 3. Many of the
fossils we find are of organisms that are still alive today. Many are of organisms that are now
extinct. 4. Fossils found in one layer of stratified rock can be very different from the fossils
found in another layer of stratified rock.
Definition 2 of 23
It is a kind of fish. It was much like the fish we see today, but its head was covered in hard plates
rather than scales. They are considered to be extinct.
What is the uniformitarian explanation for why different fossils are found in different strata?
What is a placoderm?
What is the catastrophist explanation for why different fossils are found in different strata?
What is so nice about fossils that have been encased in amber or ice?
, Definition 3 of 23
Clams and hard-shelled animals.
What kinds of creatures make up the vast majority of the fossil record?
What is so nice about fossils that have been encased in amber or ice?
What major speculation must catastrophists make when studying geology?
What major speculation must uniformitarians make when studying geology?
Definition 4 of 23
It is a creature that lived in the water and was covered in a hard outer covering. They are thought to
be extinct
What is a placoderm?
What is a trilobite?
What is required in order for petrification to occur?
What are the four general features of the fossil record?
Term 5 of 23
Can you learn much about the thickness of an organism from carbonized remains?
No. Carbonized remains come as a result of the organism being squished. They only give you a
two-dimensional view of the organism.
They do not decompose as quickly and the tissue and other soft parts tend to be preserved.
They think sediments are laid down slowly over millions of years Eventually conditions change
and the sediments harden to form rocks. The conditions in which the sediments were laid down
determine the type of sediment, which in turn determined the kind of rock formed.
They were formed by a worldwide flood. The depth, speed, and direction of the flood waters
determined what type of sediments were laid down, which in turn determined the kind of rock
formed.
