FOSSILS

By: Whitley Elzy



545-418 MILLION YEARS AG (MYA)

The Paleozoic World was

about 545 418 MYA B.C.

Paleozoic means ́ ancientlifeµ. The world was

thought to be one whole

connected land with a few

islands in the Southern

Polar area. It was called

Gondwanaland. Most

animals lived in the sea

and there was an

abundance of

invertebrates. Fossils had

told them this. (Such alie.)



417-249 MYA (MILLION YEARS AGO)

417-249 B.C Million

Years Ago makeup of the

land had changed. Theworld almost was one

super continent called

Pangaea. Vegetation had

evolved and more animals

became land animals.

This was the during the

time of Devonian,

Carboniferous, and

Permian periods.



249 B.C ± 2010

After Pangaea the

world kept moving

through Jurassic

times and more. It

eventually came to

the world we are at.Many of the animals

became extinct and

are found through

fossils.



A.D 400- 1400

Naturalist during this

time had no clue

what fossils were.

They thought that

some natural ¶plastic

force· encased the

strange objects forus. It wasn·t until

later in the 17th

century that the real

fossils were found

out.



1638-1686

During Early Paleontology many

naturalist/scientists thought that

fossils were something totally

different. It was until Niels

Stensen, or Steno, discovered.

Steno is of Danish decent and

he worked as a court physician

in Florence, Italy. The provoking

of the first idea came when he

randomly notice something. That

what humans of the world called

Tongue Stones looked vaguely

familiar to shark teeth. Lo and

behold it turned out to be shark

teeth. This was the beginning of

new findings.



1769-1832

This is when Georges Cuvier, a

French naturalist, gave a lot of

attributes to Paleontology. He

noticed that animals bones were

closely interrelated to what kind

of food they ate. He noticed this

early in his career which made

him popular. This made him

popular with other scientists

because it gave them a way to

build animals by looking at how

there bones are. Cuvier also

realized that many of the fossil

remnants were from extinct

species. Which made him write a

history saying that many were

destroyed during the BiblicalFlood.



1769-1839

William Smith was a engineer

and surveyor. He was very

important because he also

helped Geologist Scientists. He

went around in England

gathering fossils he found in

rocks. As he was collecting he

realized that the rocks with the

same fossil and fossil parts were

from the same age era.

Geologists use this to help them

with the ages of rocks. Since

Geology is the study of rocks.



1807-1873

A Swiss-born naturalist

named Louis Agassiz. He

was a special one. Heemigrated to the U.S. He was

smart and grew up to teach

history at Harvard University.

He was one of the first

people to have an interest in

Paleontology and heencouraged people to be

interested also. He became

famous from studying fish

fossils. He was influenced by

Cuvier and discovered the

origin of many rocks from,

perhaps, the biblical flood.



1870 AND 1879

Edward Drinker Cope

participated in a ´gold

rushµ for dinosaurs.Dinosaurs were being

discovered many people

around 1841. Well cope

rushed off along with

other people. He gathered

himself a team and he

along with another

famous person, Marsh,

discovered many new

dinosaur species. This

took place in Montanaand Wyoming.
