Uranium technique raises dinosaur question

Those two kinds of creatures have long been assumed to have lived together in the distant past of millions of years ago, at least in the teachings of modern Western societies. Decide for yourself if this is a case of censorship. It was two chairmen of the Western Pacific Geophysics Meeting in Singapore, a five-day conference held in August of The conference website now has the following oral presentation records: Fortunately those two could not erase the memories of those who attended the oral presentation by the Paleochronology organization. According to the New Geology web site: They did not look at the data and they never spoke with the researchers. They did not like the test results, so they censored them. Why Censor by Deletion?

Radiometric Dating and the Geological Time Scale

Maybe it was just a few thousand years old — trapped by sediment in a catastrophic worldwide flood and fossilized. Since her initial discovery, Schweitzer, a molecular paleontologist at North Carolina State University, has found red blood cells, blood vessels, bone cells and even hemoglobin and collagen. A supposedly million-year-old duck-billed dinosaur bone has also yielded soft tissue.

Dating individual fossils is a relatively straightforward (and approximate process) using stratigraphy, radio-isotope dating, looking at index fossils, or observations of .

Many such lines of evidence multiplying as at youngearth. On how to date a dinosaur, Real Science Radio’s Bob Enyart interviews Hugh Miller, a member of the international scientific team that presented at the AGU geophysical conference in Singapore, the carbon dating results from five respected laboratories around the world of bones from ten dinosaurs from the Gobi Desert in China, from Europe, Alaska, Texas, and Montana. Yet each of these dinosaurs had plenty of radiocarbon as expected in that virtually every relevant peer-reviewed paper on the topic confirms the presence of endogenous soft tissue in fossils; see DinosaurSoftTissue.

With the scientific breakthroughs and discoveries coming in daily, this is a great time to be alive! An expert on radiocarbon dating, long-time assistant professor at Loma Linda University, Dr. Paul Giem himself, graded the information presented below. You can hear that interview with Dr. He gave the original text available here a grade of A minus.

Carbon 14 doesn’t lie. Yet 14c is everywhere it shouldn’t be. Unless from a secondary source, like contamination or neutron capture described below , anything millions of years old should have NO Carbon A secondary assumption by old-earth scientists proposes that the C in diamonds coal, etc. Theoretical physicist Lawrence Krauss emphasis on the theoretical told RSR that 14c in allegedly million-year-old specimens is an “anomaly.

Britain’s six best attractions for dinosaur-obsessed kids

The most famous section of the rocks in Morrison Formation in Dinosaur National Monument, the Brushy Basin Member, is chock full of volcanic ash beds that have long since been converted to rock 1, 2, 3. It’s also chock full of dinosaur fossils, which is what makes it so famous. Is this incompatible with the theory that fossils were produced hundreds of millions of years ago? Not just no, but emphatically no. In fact, exactly the opposite applies.

Compared to the conventional theory of dinosaurs’ being at minimum 65 million years old, the time it would take soft tissue to degrade and the dating are less than 1 tenth of 1 percent of the expected age for the dinosaur fossils.

According to evolutionary scientists, radiocarbon dating also known as carbon dating is totally ineffective in measuring time when dealing with millions of years. In his book, Genes, People, and Languages, renowned Stanford University geneticist Luigi Cavalli-Sforza, in a discussion on the theory of human evolution, commented on radiocarbon dating, stating: Staunch evolutionist Richard Dawkins also dealt with the limitations of radiocarbon dating a few years ago in his highly touted book, The Blind Watchmaker.

He was even more critical of this dating method than was Cavalli-Sforza, saying: Different kinds of radioactive decay-based geological stopwatches run at different rates. The radiocarbon stopwatch buzzes round at a great rate, so fast that, after some thousands of years, its spring is almost wound down and the watch is no longer reliable. Both evolutionists and creationists stand in agreement that radiocarbon dating, which can be used only to date organic samples, is totally ineffective in measuring the alleged millions or billions of years of the evolutionary timetable.

Dinosaur Questions and Answers

How old are fossils? It can be difficult to determine the age of fossils date the fossils. Scientists can use scientific tests to determine the age of rocks near the fossils. The types of tests are called radiometric dating.

So, the oldest fossils are on the bottom layer and the newest fossils are on the top layers. If you find a layer of the right kind of igneous rocks you can use the exact dating method to .

After that comes a more difficult process: Finding a fossil merely places one organism within a time span. Finding many organisms places the group within a time span. Determining the actual existence-span of the species is very approximate. If the fossils are relatively rare, the actual existence-span may be much greater that the fossil record indicates.

Even if the fossils are relatively abundant during the species’ heyday, the number of organisms may have been small during the time of its appearance on Earth and during its demise.

Dinosaur Fossils Don’t Get Much Better Than This

Dinosaur Fossils Dinosaur Fossils: Deinos, meaning “terrible” and Sauros, meaning “lizard;” and the Latin word Fossilis, meaning “dug up. Early Discoveries A British fossil finder and ecclesiastic, William Buckland , discovered the first dinosaur fossil remains of our modern times. It was given its name in

What Does the Evidence Really Say? October 19, Images from Mary Schweitzer’s research. Full citation and links at bottom of page. Paleontologist Mary Schweitzer made worldwide headlines in for announcing that she had discovered soft tissue preserved in 65 million year old dinosaur fossils. Those who deny the scientific evidence for the old age of the earth have attempted to leverage this discovery to cast doubt on dating methods.

But that is a misrepresentation of her findings. He gives us here a summary of the issues. See also our interview with Schweitzer herself on the blog last year. For fossils as old as dinosaurs over 65 million years , the conventional wisdom has been that no original proteins from once-living cells could remain. If the delicate structure of soft body parts is discernable in a fossil, that is normally because these parts were converted to some type of hard mineral during the fossilization process.

However, over the past two decades, paleontologist Mary Schweitzer has rocked the world of paleontology by presenting visual evidence of soft tissues recovered from the interior of dinosaur bones, and biochemical evidence indicating that these are in fact the remnants of the original cells and structures from within the dinosaur bone pores. For instance, here is a network of blood vessels, containing little round red things that look like red blood cells:

Dinosaur eggs dating back 130 million years discovered by Chinese builders

James Scott What in the world is this supposed to mean?: The way that the scientific method works is that when scientists discover any empirical data that contradicts their theory or hypothesis, scientists become obliged to either throw out their theory or revise it, so that their theory conforms to the facts. They are not supposed to reinterpret the facts so that the facts conform to their theory. That would be a violation of the scientific method!

Dating dinosaurs and other fossils Fossils themselves, and the sedimentary rocks they are found in, are very difficult to date directly. Instead, other methods are used to work out a fossil’s age.

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. It is produced in the upper atmosphere. The rate at which this happens varies to some extent. Perhaps there was less C14 produced in the past, which would imply that even the relatively young C14 dates are too old. Ordinary carbon is carbon 12 C After an organism dies, if it is buried and left undisturbed, the C14 in it gradually decays into nitrogen The amount of C12 in the organism stays the same.

Thus the ratio of C 14 to C12 in the remains of the organism gradually decreases with time.

2. Why can’t carbon-14 dating be used to determine the age of dinosaur bones?

Uranium technique raises dinosaur question 02 February Share A new technique for dating fossils based on uranium’s radioactive properties could mean that palaeontologists will have to revise their theories on the end of the dinosaurs. Larry Heaman holds the sauropod specimen analysed using the new technique Image: University of Alberta A Canadian research team has used a new uranium-lead U-Pb dating technique to show that a fossilised dinosaur bone found in New Mexico is only

Dinosaur fossils, as with other fossils, are found throughout earth’s sedimentary layers. To date, approximately % of all earth’s fossil remains are marine invertebrates, % are plants, % are land invertebrates (including insects), and % are vertebrates.

Acknowledgements Introduction his document discusses the way radiometric dating and stratigraphic principles are used to establish the conventional geological time scale. It is not about the theory behind radiometric dating methods, it is about their application, and it therefore assumes the reader has some familiarity with the technique already refer to “Other Sources” for more information.

As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale. To get to that point, there is also a historical discussion and description of non-radiometric dating methods. A common form of criticism is to cite geologically complicated situations where the application of radiometric dating is very challenging.

These are often characterised as the norm, rather than the exception. I thought it would be useful to present an example where the geology is simple, and unsurprisingly, the method does work well, to show the quality of data that would have to be invalidated before a major revision of the geologic time scale could be accepted by conventional scientists.

Geochronologists do not claim that radiometric dating is foolproof no scientific method is , but it does work reliably for most samples. It is these highly consistent and reliable samples, rather than the tricky ones, that have to be falsified for “young Earth” theories to have any scientific plausibility, not to mention the need to falsify huge amounts of evidence from other techniques. This document is partly based on a prior posting composed in reply to Ted Holden.

My thanks to both him and other critics for motivating me. Background Stratigraphic Principles and Relative Time Much of the Earth’s geology consists of successional layers of different rock types, piled one on top of another.

Scientists break 75-million-year-old dinosaur fossils and find blood cells

Maiasaura History The first published description of a dinosaur occurred years before the word was created. In his Natural History of Oxford-shire Robert Plot, a professor of chemistry at the University of Oxford in , described the lower end of a petrified femur which was too large to be from any known animal in Europe; [2] the femur itself was lost, but the description as well as an accompanying engraving would lead others to determine later that it belonged to the theropod Megalosaurus.

In , the British scientist William Buckland published a paper titled “Notice on the Megalosaurus or great Fossil Lizard of Stonesfield”, the first scientifically-described dinosaur; a second dinosaur Iguanodon would be similarly-described the following year by Gideon Mantell, with a third dinosaur Hylaeosaurus discovered in Brighton in Despite having reptilian characteristics, the size and structure of the remains justified the creation of a new biological category, and in Richard Owen coined the name “dinosaur” from two Greek words meaning “terrible lizard”.

Dinosaur Fossil Dating. Many of us tend to think that the only evidence of a fossil is a bone that was carefully preserved in a rock. The truth is that a fossil can take many forms such as a print, nests, and animal droppings.
