Why are casts a fossils sometimes displayed in museums instead of the real fossils themselves?
To protect the actual fossils from theft or damage.
Answer:
For real (especially large) fossils the weight is too much to allow the bones to be strung together in an articulated fashion. Theu are after all made of stone. As consequence lighter duplicates, cast from the originals, are used.
In addition, although we think we know all the answers we can extract from fossils new techniques may allow more information to be recovered. Mounting the bones would require drilling out and loss of valuable information

Why is radiometric dating NOT used to measure fossil age?
Radiometric dating is not typically used to measure the age of fossils directly because most fossils are found in sedimentary rock, which is not suitable for radiometric dating. Instead, radiometric dating is more effective for dating the volcanic layers above or below the sedimentary layers containing fossils. Fossils themselves often lack the isotopes needed for radiometric dating, making it necessary to rely on associated volcanic materials or other dating methods, such as biostratigraphy, to approximate their age.
How fossil tell the age of earth?
Fossils can only provide an estimation of the age of the formation surrounding it. One scientific method of dating a fossil involves analysing the isotopes surrounding it. Another method involves looking at the layers of rock in which it is embedded.
Can uranium could it be used to date dinosaur fossils?
Uranium is not typically used to date dinosaur fossils directly because these fossils are usually too young for uranium dating, which is more suited for dating rocks and minerals over millions of years. Instead, techniques like radiocarbon dating are used for more recent fossils, while uranium-lead dating is applied to the surrounding geological strata. However, uranium can help date the age of the sedimentary rocks in which the fossils are found, providing context for the fossil's age.
Why can't radiocarbon date dinosaur fossils?
Radiocarbon dating cannot be used on dinosaur fossils because this method relies on the decay of carbon-14, which has a half-life of about 5,730 years. Dinosaur fossils are millions of years old, far exceeding the effective range of radiocarbon dating. By the time dinosaurs existed, any original carbon-14 in their remains would have decayed to undetectable levels, making it impossible to obtain an accurate age. Instead, scientists often use other methods, such as uranium-lead dating, to date the rock layers surrounding dinosaur fossils.
Fossils cannot be used to explain changes in the earth?
Fossils primarily provide evidence of past life forms and their evolution, rather than direct explanations for geological changes in the Earth itself. While they can indicate environmental conditions and changes over time, such as climate shifts and habitat transformations, they do not directly account for geological processes like plate tectonics, volcanic activity, or erosion. Instead, fossils serve as a complementary tool that helps scientists understand the biological impacts of these geological changes. Thus, while informative, fossils alone cannot explain the full scope of Earth's geological history.
Are political parties good for the country why or why not?
They can be. It's more of an opinion. Sometimes the parties think of what's best for themselves instead of the country.
Is dinosaur leg bone containing quartz instead of calcium fossils?
yes
Who is offended by Voodoo and why?
People are often frightened by, and sometimes offended by what they do not understand. So instead of trying to educate themselves about something, they would often rather shun it.
What do the fossilized tracks tell you about reptiles that once lived in the canyon?
Well, the tracks are examples of trace fossils. Trace fossils are not fossils in the traditional sense. Instead, they are fossils of something other than the animal or plant's form, like a animal track or burrow, that tells us an animal has been there.

Is Easter in April?
Usually but not always. Sometimes it's in March instead. (If you're Eastern Orthodox, sometimes it's in May instead.)

What are the non example for behavior?
Non-examples for behavior are situations where a behavior is not displayed, such as remaining silent when asked a question instead of responding verbally, or walking away from a conversation instead of engaging in it.
Is Answers.com sometimes irritating?
YES! because sometimes they give nonsense instead of a real answer
How is carbon-14 dating used to determine the age of dinosaur fossils?
Carbon-14 dating is not used to determine the age of dinosaur fossils. Instead, scientists use other methods like radiometric dating, such as uranium-lead dating or potassium-argon dating, to estimate the age of dinosaur fossils. These methods rely on the decay of radioactive isotopes in the fossils to calculate their age.
How is carbon dating used to determine the age of dinosaur fossils?
Carbon dating is not typically used to determine the age of dinosaur fossils because dinosaurs lived millions of years ago, beyond the range of carbon dating which is effective up to about 50,000 years. Instead, other methods like radiometric dating are used to determine the age of dinosaur fossils by measuring the decay of radioactive isotopes in the fossils.
