They can track how long that fossil has been around by using carbon dtaing. They can also use an index fossil that is in the same rock layer. When they get the date of the fossil they can figure out what it might look like and how it ate or how it moved
If two organisms share an evolutionary relationship, that means that they have a common ancestor on the evolutionary tree. The more recently the shared common ancestor lived, the more closely related the two present organisms are, evolutionarily.
Organisms sharing a common ancestor are of common descent. The LUA , the last universal ancestor, lived 3.9 billion years ago.
Fossils indicate several things about Earth's past: - the organisms that lived then, and by extension the organisms in their food chain - the climate in the area where the organism lived - how plate tectonics have moved landmasses that once were joined together
The oldest fossils of multicellular organism are from tiny algae that lived about 1.5 billions years ago. By 600 million years ago the first multicellular animals-jellyfish-like organisms -had evolved.
Paleontology is the study of prehistoric life. Paleozoology is the study of prehistoric animals. Paleobotany is the study of prehistoric plants.
Scientists use various methods to study the similarities and differences in the physical characteristics, genetic makeup, and evolutionary history of organisms that lived millions of years ago and those living today. By comparing fossils, DNA sequences, and other evidence, researchers can trace the evolutionary relationships between different species and determine how they are related to each other over time. This helps us understand the connections between ancient and modern organisms and how they have evolved and changed over millions of years.

Fossils reveal what organisms lived before us.
Scientists data can only date back to when these simple, unicelluar organisms lived and thus believe other living organisms evolved through them.
Petroleum is a substance formed from the remains of tiny marine organisms that lived millions of years ago. The organisms died and were buried under layers of sediment, where high pressure and heat transformed them into the fossil fuel we use today.
hundreds of thousands of millions of years ago is too far in the past - the universe is only 13.75 billion years old!However I know what you are asking and the organisms divided into three parts were the "trilobites". They lived about 500 million years ago.
Fossils are evidence of organisms that lived long ago. Over time, these remains can be preserved in rocks, providing valuable insight into the history of life on Earth. The study of these fossils helps scientists understand past environments and evolution.
Life Science and Earth Science are branches of Natural Science that include the study of organisms from millions of years ago.
