Fossils
This category is for questions about the bones, fragments, imprints, and other remainders from a different time. The questions and answer you will find here are history set in stone -- our past, immortalized in solid rock. You will also be able to find questions pertaining to the locations of these fossils, how you might identify them, and how they were formed.

a cast of a fossil that makes it lighter and easier to transport and study
How long does it take to form a fossil?
There are many types of fossilization. Some take a surprisingly few number of years, and others occur over periods of millions of years.
Is fossil which is present in more than one facies or environment. Body of rock with features that distinguish it from other bodies of rock
Fossilized remains of single-celled organisms similar to modern bacteria have been found in rocks more than 1.5 billion years old. These fossils provide valuable insight into Earth's ancient environments and the evolution of early life forms.
No idea is so antiquated that it was not once in modern?
modern is to antiquated as weak weak is to ?
Why aren't fossils found in metamorphic rock?
Because metamorphic rocks usually are subject to large amounts of pressure. This pressure can break down all the grains in the sedimentary rock, and the fossils will be broken down as well. It's still the same material, but it has a different shape.
What are the importance of fossils?
Fossils can be described as little traces of past life. They help in studying the history of the earth since they give important information regarding living things that were in existence and what may have caused their death.
They are fossils and fossils are fossils er gars tyre true Joy God
What is a fossil that can be used as a marker in time called?
Index fossils (also known as guide fossils, indicator fossils or zone fossils) are fossils used to define and identify geologic periods (or faunal stages). They work on the premise that, although different sediments may look different depending on the conditions under which they were laid down, they may include the remains of the same species of fossil. If the species concerned were short-lived (in geological terms, lasting a few hundred thousand years), then it is certain that the sediments in question were deposited within that narrow time period. The shorter the lifespan of a species, the more precisely different sediments can be correlated, and so rapidly evolving types of fossils are particularly valuable. The best index fossils are common, easy-to-identify at species level, and have a broad distribution-otherwise the likelihood of finding and recognizing one in the two sediments is minor. --- Wikipedia
How is earth's history interpreted and recorded?
Like a detective story Earth's history is recorded in many clues and bits of evidence available to trained observers. These include:
- Geography
- Geoogy
- Radiocarbon dating
- Chemistry
- Astrophysics
- Astronomy
The kind of rock that you are most likely to find in fossils?
Fossils are most likely to be found in sedimentary rock.
What information can the fossil record provide about patterns of diversification and extinction?
Fossils can provide information about what lived in the past. By comparing the fossils to their modern counterparts, scientists can also provide us with information about the environment in which the rock containing the fossil was deposited. Also, fossils can be used as time indicators. This can be important when trying to piece together the history of a continent because the fossil can be used to compare the ages of rocks that are separated by great distances.
In a nutshell, the fossil record can provide evolutionary information on extinction and diversification, how they died off, what their life was like, what their time period was like, and what they evolved into.
A common variety of cross bedding. Generally at a relatively low angle it resembles scooped grooves. It is formed by sand dune migration (large or small scale)
in the under ground!!! drk da derr!
u r welcome
Dude! Or lady! The person who asked the question meant what type of fossils are under ground! Ok i can answer the Question.
Root Fossil-Lileep
Skull Fossil-Cranidos
Helix Fossil-Omanyte
Armour Fossil-Shieldon
Claw Fossil-Anorith
Old Amber-Aerodactyl
And that's all the fossils. Hope that helped!
Precambrian are fossils yes or no?
Precambrian is a geologic period that extends as back as 4.500 million years ago. Fossils are very rare from that period of time.
Fossils from this era contain simple aquatic organisms with no evidence of life on land?
The answer is Proterozoic.
Does fossils support wegeners theory?
Yes, because he found fossils from a fresh water lizard, in two different continents separated by salt water.
How do scientists put back together broken fossils?
all they do is make that shape out of a exsra bone and glue it back on like nothing happened.
What conditions are required for plants and animals to fossilize?
mainly high pressure but you'll also need sediment such as rock or sand to smash it and as the soft parts of the plant decay they leave impressions on the rock
How does the fossil record show that species have changed over time?
The fossil record gives us snapshots of the life at one time. We can compare these to modern life and see what traits where key to survival and survived until today. During the age of the dinosaurs when the planet was warmer being cold blooded was an advantage and during ice ages fur and fat where greater advantages.
