No. Trilobytes are the oldest fossils ever found. They are the reason the theory of evolution is still only a theory. They were complex organisms with all the basic organs, complex eyes and a respitory sytem. If evolution is true, why for over two centuries have no fossils been found leading up to their evolutionary "place."

What two characteristics of early animals explain the scarcity of animal fossils older than the Cambrian Period?
The lorax ;)
How do you estimate the age of the Earth using fossil record?
Cannot be done as the Earth is much older than the oldest fossils.
What is the method of determining whether a fossil is older or younger than other fossils found in the many layers of sedimentary rock is called what?
relative dating
Are fossils young compared to the age of the Earth?
The oldest fossils found are considered to be from the late Archean period which ended 2500 million years ago. By contrast, the Earth is believed to be 4500 million years old. So, though both dates are amazingly old, the Earth is definitely older than the fossils.
What fossil used to compare the relative ages of fossils?
An index fossil. An index fossil's age is known, allowing scientists to know the relative age of other fossils based on their position relative to the index fossil. (Ex. If a fossil is deeper in the earth, it is older than the index fossil)
A type of trilobite is used as an index fossil. These fossils were made about 540 million years ago. A scientist finds a trilobite fossil in layer 5 in the diagram below?
Whats the answer everyone?
What is unique about finding trilobites among the first fossil creatures?
Many fossils are actually far older; some going back 5 or 6 times as far in history. However, trilobites are some of the oldest 'macroscopic fossils' (fossils of bigger things than bacteria and single-celled organisms) simply because they were there in large enough numbers and in the right conditions to be fossilised first too.
A scentist finds a rock with fossils at two different levels what she might conclude that the fossils on the bottom are older than the fossils at the top?
The fossil on the bottom would be older because as time goes on rock builds up and buries fossils so the higher it is the more recent it is.
Where are older fossils mostly found under or above younger fossils?
If the rocks containing the fossils have been involved in a mountain building episode they would be folded and if some of the folds were laid in a recumbent position and later eroded you would have older above younger rocks. Of course, it would be easy to find out if this was the case because of the various sedimentary structures in each separate layer of rock.
Carbon 14 is useful for dating fossils that are?
Carbon 14 dating is most useful for dating fossils that are up to 50,000 years old. Beyond this time frame, the amount of C-14 left in the fossil is too minimal to provide accurate dating results.
What can the scientist conclude about these birds?
Fossils in layer 5 are less than 540 million years old.
How could you tell which fossil is older?
The older fossils are found deeper than newwer ones. :3 oh wow u just thought that up

Can radiocarbon dating be used to determine the age of dinosaur fossils?
No, radiocarbon dating cannot be used to determine the age of dinosaur fossils because the half-life of carbon-14 is too short for dating objects that are millions of years old. Instead, other dating methods like uranium-lead dating or potassium-argon dating are used for dating dinosaur fossils.
What evidence is there that earth has had a succession of flora and fauna?
Fossils!Fossils are the 'remains' of plants and animals (including humans) which lived in the past. Millions of fossils have been found all over the world. They show clearly that different species of plants and animals lived in the past and that they changed over long periods of time. Older fossils are simpler than younger fossils and we can work out the sequence of evolution from these fossils.For example the oldest vertebrate (backboned) fossils are fish. Younger than these are the first amphibians. Then reptiles appear as fossils, followed by birds and mammals.See:http://animals.about.com/od/evolution/a/vertebrateevolu.htmhttp://txtwriter.com/Backgrounders/Evolution/EVpage01.htmlhttp://evolution.berkeley.edu/evosite/lines/Ifossil_ev.shtmlhttp://www.fossilmuseum.net/

Is a limestone bed containing fossils that are 550 million years old older than a bed of sandstone containing fossils that are 400 million years old?
550 million years old
