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.

How would you explain finding a fossil fish on the side of a mountain nowhere near water?

Because there truly was a great flood that covered the earth. Scientists have discovered fossilized “tropical” plants as well on top of mountains that could never be populated by such types due to the temps. This information has either been purposely changed or hidden from the majority. The evidences of the Bible have always been around us, you just have to search them for yourself. Just like the brainwashing idea that we humans/ earth have been here for millions of years! That’s one of the biggest lies ever told!

How does a fish fossil get to the desert?

well, everything was water at one point so fish fossils get there pretty easy because when the dinosaurs were here it was tropical not a desert.

Do fossils of certain organisms appear more then once then one continent?

Yes, fossils of certain organisms such as dinosaurs have been found on multiple continents, indicating the widespread distribution of these species in the past. This phenomenon can be attributed to factors like continental drift and migration patterns of these organisms.

How does radioactive dating relate to fossils and radioactive waste?

There are a number of types of radiometric dating. Carbon-14 dating, which is perhaps best known, can only be used for things some thousands of years old at most, and so is not particularly useful for fossils. Other types of radiometric dating, however, are good for hundreds of thousands or millions of years, and these are very useful for fossils. In fact they can be used to estimate the ages of various kinds of rocks.

Radioactive waste is a pollutant that affects some radiometric dating techniques, skewing them. For example, above ground nuclear testing in the 1950s and 1960s produced waste carbon-14, almost doubling the amount in the atmosphere for some time. This would make samples from that period appear too new.

Most radioactive materials in nuclear waste or pollution would not have this sort of effect, however. In order to influence radiometric dating, the material measured has to be part of the pollution or has to be generated from it. Carbon-14 results from a collision of a neutron with nitrogen-13 (a hydrogen atom is also generated). But this happens in the upper atmosphere as a result of cosmic rays. There are very few sources of neutrons on Earth, with uranium-235 probably being the most common. So ordinary nuclear waste from such sources as power plants will not usually skew carbon-14 dating.

On the other hand, the isotopes other than carbon-14 that are used in radiodating may be among those in nuclear waste. Among the isotopes that might be affected are those used in iodine-xenon dating, rubidium-strontium, and potassium-argon dating. Nuclear pollutants might include these isotopes in them, and so exposure would possibly skew results.

There are other forms of pollution that affect carbon dating. Burning of fossil fuels increases the amount of carbon dioxide in the atmosphere without increasing the amount of carbon-14. This would make some samples from the period after about 1700 appear too old.

How is fossil evidence of evolution dissproved?

Fossil evidence of evolution is not typically disproved, as fossils are considered crucial pieces of evidence in supporting the theory of evolution. However, the interpretation of fossil evidence can sometimes be open to debate or revision based on new discoveries or scientific understanding. Overall, the accumulation of diverse fossil evidence provides strong support for the concept of evolution and the relatedness of different species.

What geologic time period was the trilobite fossil associated?

Trilobites were associated with the Paleozoic era, from the Cambrian to the Permian.

Why would it be difficult to use fossils to learn how organisms such as worms have changed over time?

Because you will have to excavate (dig) in the areas where the creatures once were, which there aren't any verified locations, making it difficult to find them.

How do you determine where water is leaking through from the second floor showertub to the kitchen below?

You need to do a leak test on the tub and shower. To ch'k the drain fill tub about 1/2 full without running the tub faucet next plug shower head and tub spout turn water on this will ch'k faucet Next run water on shower doors this is where the majority of leaks are found water running out and down the corner of the unit If tiled also ch'k tile grout.

How do fossils help us?

they help us discover what animals were alive here

How old they were and stuff like that

How the age of plant and animal fossils is determined?

The age of a plant or animal in a fossil is determined by radiocarbon dating. This means scientists measure the amount of a special type of carbon in the fossil, to determine the date.

Is it generally considered that dinosaurs lived in warm climates yet fossil remains are found in antarctica how can this be explained?

It's important to remember that dinosaurs lived between 230 million and 65 million years ago. The world was very different back then, with temperatures much higher than today's average and even different continental layouts. During this time, Antarctica was just below the polar circle, and still some ways away from permafrost. This would have allowed any species that lived there- dinosaurs included- at least half a year of permanent sunlight at tropical weather, yet plenty of room to move northward when the southern half went into a winter of permanent night.

Are Natalie and Musa dating each other?

No, but Natalie Fotopoulos and Musa Cooper did dance impressively on So You Think You Can Dance (season 2, 2006).

Where can be fossils be found in Europe?

Fossils can be found in various places in Europe, including sedimentary rock formations, quarries, cliffs, caves, and coastal areas. Some well-known fossil sites in Europe include the Jurassic Coast in England, the Solnhofen Limestone in Germany, and the Monte San Giorgio in Switzerland. Paleontologists and fossil enthusiasts often search for fossils in these locations.
