In ancient times, fossils inspired legends of monsters and other strange creatures. Look at the two photos below and try to trace the origin of the creature on the left. The griffin, a mythical creature with a lion Ammonites left and elephant skull right. Ancient Greeks named ammonites after the ram god Ammon since they look like the coiled horns of a ram. Can you see why? Many of the real creatures whose bones became fossilized were no less marvelous than the mythical creatures they inspired Figure below. Other fossils, such as the trilobite Kolihapeltis sp c impress us with their bizarre forms. These suture marks on an ammonite fossil d display a delicate beauty.

See this page in: Hungarian , Russian , Spanish People who ask about carbon 14C dating usually want to know about the radiometric  dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years. People wonder how millions of years could be squeezed into the biblical account of history. Clearly, such huge time periods cannot be fitted into the Bible without compromising what the Bible says about the goodness of God and the origin of sin, death and suffering —the reason Jesus came into the world See Six Days?
Christians , by definition, take the statements of Jesus Christ seriously.
What would be the two methods of dating fossils and explain each? relative and absolute. relative is determining the relative order of past events, without necessarily determining their absolute age. Absolute is the process of determining a n approximate computed age in archaeology and geology.
Important We believe any unbiased reader will realize that we were fair with our treatment of the two models in the table above. Yet, although the theory of evolution matches the facts in some cases, evolution is still an unproven theory. By now, you may believe it should be your first choice also. Unlike many others that preceded us, we attempted to find a clear defense of evolution for two reasons: To keep from being accused of bias. To keep from making claims that someone could refute later.
Even though there are a great number of claims in books and on the Internet, we could find no scientific, testable facts that support the theory of evolution.

Is the Cambrian Explosion Problem Solved? Called the “Cambrian explosion of life,” the creatures in these layers come from all the major groups of animals alive today including fish, which represent the vertebrates , plus many more that later became extinct. Evolutionists, starting with Charles Darwin, have had a difficult time explaining why such richly diverse aquatic life forms appeared so suddenly and with no trace of evolutionary ancestry in lower pre-Cambrian rocks.
According to neo-Darwinism, new life forms develop through time, chance, and death. Without the time, the formula cannot work, and yet Cambrian fossils are a parade of well-designed creatures that lived at the same time, not in separate evolutionary ages. This problem is what some scientists term the “Cambrian Conundrum,”1 and researchers recently made another attempt to solve it.
The standard tale is that Cambrian creatures did not evolve until about million years ago. In contrast, these authors suggested that animals were actually alive and evolving million years ago.
Sedimentary Rocks Formation and Fossils!
So, how do we know how old a fossil is? There are two main methods determining a fossils age, relative dating and absolute dating. Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.
Relative Dating The majority of the time fossils are dated using relative dating techniques.
Findings in the two ways, transitional fossils and more often the fossils explain both choices c and chronometric dating fossils intrigues almost everyone. Dating and chronometric dating. Amino acid dating methods geologists are the two ways of rocks there are.
Definition Triceratops skeleton, Natural History Museum of Los Angeles County Under phylogenetic nomenclature , dinosaurs are usually defined as the group consisting of Triceratops , Neornithes , their most recent common ancestor MRCA , and all descendants. In traditional taxonomy, birds were considered a separate class that had evolved from dinosaurs, a distinct superorder.
However, a majority of contemporary paleontologists concerned with dinosaurs reject the traditional style of classification in favor of phylogenetic taxonomy; this approach requires that, for a group to be natural, all descendants of members of the group must be included in the group as well. Birds are thus considered to be dinosaurs and dinosaurs are, therefore, not extinct. Birds are classified as belonging to the subgroup Maniraptora , which are coelurosaurs , which are theropods, which are saurischians , which are dinosaurs.

What are the two ways that geologists can date a rock stratum? Radiometric dating and fossil dating Why does the presence of fossils in rocks all over the world present a problem for those who believe the history of the earth involved mostly slow changes caused by the same processes we see today?
These are the same folks who insist clam fossils on top of Mt. Everest prove Noah’s flood happened because it proves the fact the land was once underwater, and when pressed about the fact there’s not enough water to flood the Earth to that level will explain that no, before the flood all the land was flat so there was enough water, and the mountains rose up after that.
So, their rationale is that the fossils found there are the result of the flood because the only possible explanation is that at one time all that land was beneath the water and rose up out of it to form mountains These are the same people who insist all the layers of the geological column were laid down by Noah’s flood, but also claim Noah’s flood carved the Grand Canyon out of the geological column without realizing the contradiction in those two ideas.
Did the flood lay down the column, or did it carve the canyon out of the column already there? These are the same people who, in one breath, will decry carbon dating as being entirely unreliable and false and wrong, and then turn around in the very next breath and claim carbon dating proves the Earth is young because they’ve carbon dated coal veins that were very young, and someone carbon dated a dinosaur bone and it was only 20, years old.
These are the same people who claim the flood must have happened because over cultures around the world have flood related legends, so that proves the survivors wrote about it These are the same folks who announce that if you run lunar recession backward, the moon would come crashing into the Earth less than thirty-thousand years ago, without bothering to crunch the numbers and find out if you run back the lunar recession the moon would have been just a smidge over one kilometer closer to the Earth thirty-thousand years ago a drop in the bucket for its current distance of , or so mean kilometers.
These are the same exact folks who will tell you the Bible is absolutely correct about the Earth being only 6, years old or so, and then point to the existence of Jericho a city roughly 10, years old to prove it. I could go on all day, but the point is, you shouldn’t spend very long looking for consistency or critical thought from these people.
Your mind will starve to death for lack of it in your search.

Unlike the radioactive isotopes discussed above, these isotopes are constantly being replenished in small amounts in one of two ways. The bottom two entries, uranium and thorium , are replenished as the long-lived uranium atoms decay. These will be discussed in the next section.
Feb 02, · Best Answer: Fossils are casts of one living life forms. potassium-argon dating. Use to date very old fossils. Measures the decay of one isotope into another. Index fossils: Certain fossils appear for only a short : Resolved.
This is what archaeologists use to determine the age of human-made artifacts. But carbon dating won’t work on dinosaur bones. The half-life of carbon is only 5, years, so carbon dating is only effective on samples that are less than 50, years old. Dinosaur bones, on the other hand, are millions of years old — some fossils are billions of years old. To determine the ages of these specimens, scientists need an isotope with a very long half-life.
Some of the isotopes used for this purpose are uranium , uranium and potassium , each of which has a half-life of more than a million years. Unfortunately, these elements don’t exist in dinosaur fossils themselves. Each of them typically exists in igneous rock, or rock made from cooled magma. Fossils, however, form in sedimentary rock — sediment quickly covers a dinosaur’s body, and the sediment and the bones gradually turn into rock.
But this sediment doesn’t typically include the necessary isotopes in measurable amounts. Fossils can’t form in the igneous rock that usually does contain the isotopes. The extreme temperatures of the magma would just destroy the bones.

A sedimentary rock is just what it sounds like: Sedimentary rocks can consist of sand, clay, chalk and fossils and as a marine geologist I find sedimentary rocks very fascinating! Some may think that sedimentary rocks is a bit dull since sedimentary rocks isn’t created by violent and exciting volcano eruptions from the Earths mantle like the igneous rocks.
No, sedimentary rocks have another type of fascinating origin and every single rock tells a story if you just know how to “read” the rock! That is one of the fascinating thing with sedimentary rocks! The other exciting part with sedimentary rocks is that they tell us about Earths history!
Scientists use two kinds of dating techniques to work out the age of rocks and fossils. The first method is called relative dating. This considers the positions of the different rocks in sequence (in relation to each other) and the different types of fossil that are found in them.
September Evolution theory explains how organisms have changed over time. The fossil fish Priscacara liops found in sediments dating from the Eocene epoch Scientific understanding requires both facts and theories that can explain those facts in a coherent manner. Evolution, in this context, is both a fact and a theory. It is an incontrovertible fact that organisms have changed, or evolved, during the history of life on Earth.
And biologists have identified and investigated mechanisms that can explain the major patterns of change. There are four major patterns of change.
Physics Organic matter in the fossil record generally dates by carbon 14 C14 dating to about 20, to 40, years. Why are the dates so different? Many creationists believe that radioactive decay was faster in the past. However, in this talk I want to concentrate on reasons to believe the C14 dates are more accurate and that they give evidence that all life on earth is very young.
If decay rates were faster in the past, then even the C14 dates could be too old. How Carbon 14 Is Produced and Decays Carbon 14 is an isotope of carbon with two extra neutrons in the nucleus.
The scripture that states: Here are the scriptures in context: KJV So, what does all this mean? God and Adam would walk together and have fellowship. Then Adam sinned and became a mortal being, destined to die. So, God raised up Seth in attempt to reestablish a righteous line of people for himself. This is one of the parables that Jesus explained, so we know, for sure, that the field is the world Matthew Therefore, if we put this all together, it appears that Abel and Seth were righteous the seeds of God , and Cain was evil including his offspring the Daughters of Men — seeds of the enemy.
Here is a scripture that supports this notion: And wherefore slew he him? KJV Another way of looking at it is that the sons of God would be good seed coming from God, not yet fallen into unrighteousness; and, the daughters of man were bad seed coming from man, who at this time had fallen into unrighteousness. So, the righteous seed was Abel and the evil seed was Cain, but Cain killed Abel.
How accurate are Carbon-14 and other radioactive dating methods?
Let me know if you find any honest politicians while you’re at it! Other faiths do not necessarily attempt to answer the question “How did we get here? Guru Nanak, the founder of the Sikh faith, talked of planets beyond planets and moons beyond moons, suns beyond suns and seas and lands beyond measure throughout universe s that we could not comprehend. He wrote this over years ago.
I am not pushing a faith, by the way. Sikhism doesn’t believe in conversion and does not claim to have a monopoly on wisdom.
