It is not so much the fossils themselves but the fossil record that show us that the environmental conditions have changed.
The evolution of the Earth's Biosphere (living things, the oceans, land surface and atmosphere) began about 3600 million years ago when the atmosphere and oceans had no free Oxygen in them. The first life on Earth (blue green alga and 'stromatolites) slowly produced Oxygen and these are the only fossils we find from this time. As oxygen was produced over the next 3000 million years, it caused iron to be deposited out of the sea water (forming our banded Iron ore deposits) and slowly changing the atmosphere. As the Oxygen built up more complex life forms developed and by 5-600 million years ago the fossils of hard shelled sea creatures are found. Slowly more and more oxygen was released from the sea into the atmosphere and at about 425 million years ago we begin to see the fossils of the first land plants. Animals then began to follow the plants out of the seas onto land and we see fish and amphibian fossils then came the age of the reptiles (dinosaurs) and as we get nearer to the present more and more and more varied animals are found as fossils. Thus Life CREATED the Environment and the fossils prove this. They can be in cold climates or be in hot weather. It depends what their climate is. (:
What else can I help you with?
How do fossils show changes in related species?
Fossils are used to show changes because they are permanent. These fossils are also old and show evolutionary changes in species alive today.
What five ways that organisms can be preserved as fossils and explain what fossils can show about earth's history?
Organisms can be preserved as fossils through several methods, including permineralization (minerals infiltrating bone or wood), natural casts (sediment filling in the shape of an organism), amber preservation (organisms trapped in tree resin), freezing (organisms preserved in ice), and desiccation (organisms dried out in arid conditions). Fossils can reveal crucial information about Earth's history, such as the types of organisms that existed at different times, evolutionary transitions, and past environmental conditions. They also provide insights into extinction events and the changes in biodiversity over geological time. By studying fossils, scientists can reconstruct ancient ecosystems and understand the Earth's climatic shifts.
Fossils show that there have been many?
Fossils show that there have been many different species of organisms that have lived on Earth throughout its history. These fossils provide important clues about the evolution and biodiversity of life on our planet.
How can rocks show that changes take place?
Rocks can show changes through processes like sedimentation, metamorphism, and weathering. The presence of different types of rocks, such as sedimentary, igneous, and metamorphic, can indicate past environmental conditions and overall geological change over time. Fossils found in rocks can also demonstrate biological changes that have occurred.

Does the ring growth pattern on trees depends on environmental conditions?
The rings will be laid down no matter what the conditions, the rings will show what the conditions were on that season.
How do fossils show how organisms have evolved through time?
Fossils provide valuable evidence of how organisms have evolved over time. By studying the structure, shape, and characteristics of fossils, scientists can observe unique features that have changed or stayed the same. Fossils also help in understanding the transition from one species to another and provide a record of extinct species, giving insights into the diversity of past ecosystems and the evolutionary journey of life on Earth.
How do fossils show changes in related species?
Fossils are used to show changes because they are permanent. These fossils are also old and show evolutionary changes in species alive today.

What can fossils tell you about how life changed through time?
Yes, they can show you life back then compared to now. Also the dirtier the fossil the older the fossil.By:Donny Heitler
How are fossils used to show changes in Antarctica?
plant fossils (glossopteris) were found there.
Fossils show that there have been many?
Fossils show that there have been many different species of organisms that have lived on Earth throughout its history. These fossils provide important clues about the evolution and biodiversity of life on our planet.

The presence of different types of rocks, such as sedimentary, igneous, and metamorphic, can indicate past environmental conditions and overall geological change over time. Fossils found in rocks can also demonstrate biological changes that have occurred.
Do fossils show a complete history?
No. Because there are not enough fossils to do any more than to guess.
How can fossils help show that continental drift happened?
It can help show that continental drift happened, if you find the same fossils on different continents. This would mean that the continents had to be close together if the fossils are found on land.
How do fossils help geologists?
Geologists use fossils to interpret past environments, age rock layers, and understand the history of life on Earth. Fossils can provide information about the evolution of species, past climate conditions, and even the movement of continents over time. By studying fossils, geologists can reconstruct the Earth's history and better understand geological processes.
Why are fossils important scientists?
In simplest terms, fossils show what living things were like long ago.
