soft tissue in dino & other fossils(notes)-nothing in science justifies millions of years ages
How Exactly Do They Date Fossils?
Carbon dating cannot be used to determine the age of dinosaur fossils because. Old meets new technology determines age of fossils. In a gram of carbon, you can calculate the number of. The low activity of the carbon. Because it contradicts . Please just facts on why it cannot be used for dating dinosaur bones. Carbon is considered to be a highly reliable dating technique. It's accuracy has been verified by using C to date artifacts whose age is known historically. The fluctuation of the amount of C in the atmosphere over time adds a small uncertainty, but contamination by "modern carbon" such as decayed organic matter. By looking at the ratio of carbon to carbon in the sample and comparing it to the ratio in a living organism, it is possible to determine the age of a formerly living thing fairly precisely. Because the half-life of carbon is 5, years, it is only reliable for dating objects up to about 60, years old. However, the.
Started by thaphantumApril 15, Posted April 15, However, the principle of carbon dating applies to other isotopes as well. Dinosaur fossils are usually found in sedimentary rock. Sedimentary rock layers strata are formed episodically as earth is deposited horizontally over time.
Newer layers are formed on top of older layers, pressurizing them into rocks. Paleontologists can estimate the amount of time that has passed since the stratum containing the fossil was formed.
Generally, deeper rocks and fossils are older than those found above them. Observations of the fluctuations of the Earth's magnetic field, which leaves different magnetic fields in rocks from different geological eras. Dating a fossil in terms of approximately how many years old it is can be possible using radioisotope-dating of igneous rocks found near the fossil. Unstable radioactive isotopes of elements, such as Uranium, decay at constant, known rates over time its half-life, which is over read article years.
An accurate estimate of the rock's age can be determined by examining the ratios of the remaining radioactive element and its daughters. For example, when lava cools, it has no lead content but it does contain some radioactive Uranium U Over time, the unstable radioactive Uranium decays into its daughter, Lead, at a constant, known rate its half-life.
By comparing the relative proportion of Uranium and Lead, the age of the igneous rock Carbon Dating Cannot Be Used To Determine The Age Of Dinosaur Fossils Because be determined. Potassium which decays to argon is also used to date fossils. To determine a fossil's age, link layers volcanic rock beneath the fossil predating the fossil and above it representing a time after the dinosaur's existence are dated, resulting in a time-range for the dinosaur's life.
Thus, dinosaurs are dated with respect to volcanic eruptions. TrueThat said earlier that they found "soft tissue" in dinosaur bones It's very unlikely that carbon 14 dating is wrong. There are some factors which can make it inaccurate, but they occur very rarely. Posted April 15, edited.
Evolutionary science theory molecules-to-man is structureless, and predicts virtually nothing - It adapts to data like fog adapts to landscape. Rather put a bit of faith in physics, genetics, chemistry, biochemistry, physiology etc Bacteria will not become anything else than It will be detrimental to the theory that everything came from a common ancestor. Carbon 14 is only accurate up to 70, years How do scientists determine all of the dates that they give for when the dinosaurs lived, when humans came along, etc.?
We tell the age of dinosaurs from the rocks they were in or other better known and dated fossils found along with them or near them, particularly mammal teeth and small sea creatures. We can only date a rock precisely if it was made from a volcano — not by gradual buildup like most dinosaurs are found in. Volcanic rock contains some radioactive minerals in tiny amounts. These minerals break down over time at a very steady rate.
By measuring how much of these minerals have broken down we can date such a volcanic rock to withinyears of when it was made, even if it was many millions of article source ago. Of course, such volcanic rock isn't always around dinosaur fossils. So often we have to guess from these other clues.
Also, Carbon dating is obviously useless for dating the ages of dinosaurs, Carbon dating is used for human civilisations - aging Egyption mummies ect ect. To gain the age of anything before humanity and the uprise of Mammals, Radiometric dating is used.
This method is based upon radioactive decay. This rate of decays occurs at a specific and constant rate. The age of a rock can be determined by measuring the amount of the daughter product and adding that to the amount of the remaining parent material. The parent element must decay rapidly enough to produce measurable amounts of the daughter element, but measurable amounts of the parent element must also be present in the sample. These systems meet the standards listed above.
Here alive, plants and animals incorporate these isotopes of carbon into their tissues at the ratio found in the atmosphere. Carbon Dating Cannot Be Used To Determine The Age Of Dinosaur Fossils Because death, the Carbon 14 in their tissues begins to decay.
By measuring the remaining amount of Carbon 14, the age of the fossil can be determined. This method can be used to date material ranging in age from a few hundred years to about 50, years. The use of Carbon 14 permits the determination of age directly a fossil. For fossils greater than 50, years old, the age of the fossil is found indirectly by determing the age of the rock associated with the fossil.
Carbon 14 dating has a dating range of several hundred years before present to 50, years before present. How do you explain measurable amounts of Carbon 14 in fossils presumably millions of years old. Theoretically these fossils should be utterly void of any Carbon 14, yet up to 10 times the detection limit is found almost ubiquitously among "supposedly carbon dead" specimens. I'd guess whatever carbon 14 is left in a fossil, isn't managable for dating back to a specific time line.
Which is why Radiometric is used insead. Then, the fossils found within each layer were classified by that layer i. Date the strata by what fossils are found in it. As time went on, strata were not found to be uniform in layering, and so the fossil type that was found in each strata was used to label the strata. The problem is this: Java Man Pithecanthropus - Ina skull cap, femur, and two molar teeth were grouped together as belonging to the same person. The skull is that of an ape, but the teeth and the femur bone of an human.
What was not published was that they were found 45 feet apart from each other, along with many other bones of clearly apes, humans, and other animals.
No, his objection was that the Paleochronology group was using the reports as evidence that dinosaurs lived thousands, not millions, of years ago. If we apply the standard assumptions that scientists typically apply when using carbon dating, we come up with these simple results: Dating is one of the most reliable. The point is it is an absolutely perfect representation of Brachiosaurus, known only from East Africa and North America.
Java man has since been reclassified as human. Neanderthal Man Homo sapiens neanderthalensis -in Neanderthal, Germany, a skull cap and limb bones were found. It was grouped with a set of skeletons found all over Europe that had the following characteristics: The overall skeletons were short, and stooped-over.
However, years later, it is now admitted that these skeletons were of people that suffered from rickets, and syphilis. Neanderthal Man was just a variation of the modern human kind with disease! The Piltdown Man Eoanthropus. Lucy Ramapithecus - once widely accepted as the direct ancestor of humans, it has now been realised that this skeleton is merely an extinct type of orangutan - not an early human. I don't know how many of these are of actual fact - apart from the piltdown man, it is a well known fraud.
Yes, more than one Yes but homo sapien ancestors are apeish correct? How are we sure these aren't just more monkeys with big brains? Of the fruads she mentioned, However there is overwhelming evidence that our ancesters did exist even during homo sapien expansion - with the neandethals.
It's a classic case of natural selection and adaptation, but still those mentioned were frauds but the way she wrote it made it to seem that homo sapiens have no ancesters and we just popped up from a cabbage patch. I apologize if I read your post wrong in the first place if that was not your intention.
Dinosaur Fossil Dating - Enchanted Learning Software
Posted April 16, You do know that anyone can write and edit a wiki and that anyone can create a webpage, right? That link make them true. Minerals in surrounding material slowly replace the organic matter of the thing being fossilized.
This creats a "rock" which fills the space of the thing that died. Also, if you don't believe evolution is real, might I suggest reading some things which were written in the last hundred years. There is a lot of information that we have now that they did not have years ago.
Carbon dating cannot be used to determine the age of dinosaur fossils because
I also don't see that it could affect the theory that evolution explaines the origin of species'. But--depending on the magnitude of error--theories on how exactly evolution of life on earth went might need major reconsideration. Theories on the course of evolution would most probably be incorrect.
But I'd still apply the principles of evolution for trying to understand. They also use the depth that the fossil is buried at to determine its age, which is a fairly accurate dating method. They probably haven't got fossil ages wrong.
Posted April 17, Go here did you read that all stalactities take tens of thousands of years to grow? It depends on the mineral and conditions of the deposit. I can grow stalactities in my kitchen in minutes depending on the mineral. MOST stalagtites and stalactities grow from minerals and conditions that take many thousands of years because of the minerals they are based upon. Fossilization occurs when minerals diluted in a usually liquid medium like water replace the orgainic matter.
These then solidify over time. Sometimes they are affected by further heat and pressure over time.
Pass it on to friends: Click to see where it had been on the Conference website. Dinosaur bones are supposed to be around 65 million years old, right?
It would be impossible to test the millions of years old solution for diluted minerals before fossilization. I would suggest you take a geology class in a real college sometime.

They will show you how stratigraphy and other methods we reliably use to date a number of rocks.
