The bone was 68 million years old, and conventional wisdom about fossilization is that all soft tissue, from blood to brains , decomposes. Only hard parts, like bones and teeth, can become fossils. But for some people, the discovery raised a different question. How do scientists know the bones are really 68 million years old? Today’s knowledge of fossil ages comes primarily from radiometric dating, also known as radioactive dating. Radiometric dating relies on the properties of isotopes. These are chemical elements, like carbon or uranium, that are identical except for one key feature — the number of neutrons in their nucleus. Atoms may have an equal number of protons and neutrons.
Scientists break 75-million-year-old dinosaur fossils and find blood cells
They will not allow others to date bones in their possession! Our Paleo team has Carbon 14 dated dinosaur bones from Texas, Colorado, Montana, China, North Dakota, and Alaska by professional labs using accelerator mass spectrometry. Every sample dates to between 23, and 39, years before the present. Did Asteroids kill the dinosaurs? When did Asteroids hit.
Imagine the impossibility of a dinosaur bone not turning to stone, not decaying and crumbling to dust and the contents inside the bone surviving. Our team published a paper in Scientific article on dating dinosaur bones in Germany and in the National Research Council of Italy in C DATING OF DINOSAUR BONES.
Dinosaurs supposedly died out 65 million years ago. Several tests were done by the University of Georgia using accelerator mass spectrometry. The age for all these fossils was found to be less than 50, years 1. This is not predicted by conventional evolutionary theory; and other discoveries have been made concerning dinosaurs which also are not predicted by evolutionary theory such as the discovery of soft tissue in bones that are not or are only partially fossilized.
However, the abstract of the Miller presentation was removed from the website for the conference. If the accepted ages of millions of years for dinosaurs were to be found to be in error, this would be a problem to evolution. The dinosaur dates reported below and discussed in the AOGS paper discussed throughout this article, included triceratops, hadrosaur, allosaurus, and acrocanthasaurs. Below is a list of some dinosaur fossils and their dated ages from the Miller paper. An apatosaurus was found in late Jurassic strata of the Morrison formation, and excavation was done in and
Dinosaur Questions and Answers
Exploring the wonders of geology in response to young-Earth claims Please read my guidelines and background posts before proceeding! Saturday, February 12, Direct radiometric dating of dinosaur bones using the U-Pb method, and ICR’s attempt to avoid the issue Well, they’ve finally done it. In a Geology article published last month, Fassett et al. In addition to applying a known dating method to a completely new type of sample, the authors’ specific goal was to demonstrate from independent evidence that dinosaur bones found in an early Paleocene sandstone were not inherited from older strata.
Carbondated dinosaur bones are less than 40, years old. carbon dating dinosaur bones carbon dated dinosaur fossils date c dinosaur fossil bones by c14 dinosaur bones fossils. Researchers have found a reason for the puzzling survival of soft tissue and collagen in dinosaur bones – the bones are younger than anyone ever guessed.
Senior research scientist Alexander Cherkinsky specializes in the preparation of samples for Carbon testing. He directed the pretreatment and processing of the dinosaur bone samples with the Accelerator Mass Spectrometer, though he did not know the bones were from dinosaurs, and he signed the reports. Carbon dating at this facility is certainly the very best. But in , someone told the director of the facility, Jeff Speakman, that the Paleochronology group was showing the Carbon reports on a website and YouTube and drawing the obvious conclusions.
So when he received another bone sample from the Paleochronology group, he returned it to sender and sent an email saying: The scientists at CAIS and I are dismayed by the claims that you and your team have made with respect to the age of the Earth and the validity of biological evolution.
Did Humans Walk the Earth with Dinosaurs? Triceratops Horn Dated to 33,500 Years
The only direct way we have of learning about dinosaurs is by studying fossils. Fossils are the remains of ancient animals and plants, the traces or impressions of living things from past geologic ages, or the traces of their activities. Fossils have been found on every continent on Earth, maybe even near where you live. The word fossil comes from the Latin word fossilis, which means “dug up.
When radiocarbon dating any fossil bone, not just dinosaur bones, it is usually the case that samples from different places on the same bone yield results within a broad range. Therefore it is best practice to sample several fractions of a bone when possible.
Since it was first found it has given its name to a new group of dinosaurs called the Neovenatoridae. This group itself forms part of the Carcharodontosauridae which are closely related to the North American dinosaur Allosaurus. Neovenator walked on its long hind legs. The first specimen was found with shoulder blades scapulae but was missing the remainder of its arms. Reconstructions have been based on those of Allosaurus. There were three clawed toes on each foot and it is likely that there would have been three digits on each hand.
The long body was held in balance by a long tail. The type specimen measured about 7.

Fossil specimen of Stegosaurus stenops shown as it was found. This is the best-known species of Stegosaurus, mainly because its remains include at least one complete articulated skeleton. It had large, broad plates and four tail spikes. It was shorter than S. Stegosaurus longispinus, meaning “long-spined roof lizard”, was named by Charles W. Gilmore  and known from one partial skeleton, from the Morrison Formation in Wyoming.
Dating Dinosaur Bones Creation Research has received the following question: What is the reason for dinosaur bones being carbon dated “billions” of years before humans? Answer from John Mackay: Many of you will realise that this is a totally misplaced question, albeit probably a genuine.
Carbon , Radiometric Dating and Index Fossils Carbon dating is used to determine the age of biological artifacts up to 50, years old. This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils like those of the dinosaurs alleged to be millions of years old. This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers. Carbon dating has been used successfully on the Dead Sea Scrolls, Minoan ruins and tombs of the pharaohs among other things.
Carbon is a radioactive isotope of carbon. The half-life of carbon is approximately 5, years. The short half-life of carbon means it cannot be used to date fossils that are allegedly extremely old, e. The question should be whether or not carbon can be used to date any artifacts at all? The answer is not simple. There are a few categories of artifacts that can be dated using carbon ; however, they cannot be more 50, years old.
Carbon cannot be used to date biological artifacts of organisms that did not get their carbon dioxide from the air.
How accurate are Carbon-14 and other radioactive dating methods?
November 26, According to new research, iron in the dinosaur’s body preserved the tissue before it could decay. The research, headed by Mary Schweitzer, a molecular paleontologist at North Carolina State University, explains how proteins — and possibly even DNA — can survive millennia.
God in a Nutshell project is a News, Real Science, Archaeology, Ancient Discovery, Prophecy, Torah, Ancient Text website (like is seen in the C dates of dinosaur bone below) Summary on Carbon Dating of Dinosaur Bones. Whatever the case, the Carbon 14 in dinosaur bones “issue” for the evolution segments of the academic world seems.
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.
How Do Scientists Determine the Age of Dinosaur Bones?
Ancient Molecules and Modern Myths The author of this article deals with creationist osteocalcin claims. The ancient surviving materials they commonly refer to are fragments of hemoglobin and osteocalcin a bone protein extracted from dinosaur bone. There are many problems with their position, but ultimately it reduces to nothing other than they just don’t think that organic molecules can last a long while.
The “Creation Science” approach is to deny the independent results of geology, chemistry and astronomy because these molecules exist. I will not take the time in this essay to address the problematic origins of “creation science” in the United States or elsewhere and instead refer the interested reader to The Creationists:
Jun 09, · Scientists break million-year-old dinosaur fossils and find blood cells to allow them to break off pieces of ancient dinosaur bone for the experiment. undetermined dinosaur dating .
Various specimens of Tyrannosaurus rex with a human for scale. Size comparison of selected giant theropod dinosaurs, with Tyrannosaurus in purple. Tyrannosaurus rex was one of the largest land carnivores of all time; the largest complete specimen, FMNH PR ” Sue ” , measured The forelimbs were long thought to bear only two digits, but there is an unpublished report of a third, vestigial digit in one specimen. The tail was heavy and long, sometimes containing over forty vertebrae, in order to balance the massive head and torso.
To compensate for the immense bulk of the animal, many bones throughout the skeleton were hollow, reducing its weight without significant loss of strength. It was extremely wide at the rear but had a narrow snout, allowing unusually good binocular vision. These and other skull-strengthening features are part of the tyrannosaurid trend towards an increasingly powerful bite, which easily surpassed that of all non-tyrannosaurids.

Neutron Capture in Carbon-Dated Dinosaur Bones? That’s Way Too Awkward
Triceratops Montana Blatant Censor Instead of Correction If some scientist giving a lecture in a science conference makes a mistake, why not correct that mistake? Conference leaders may add an addendum to the official website, after the oral presentations are completed, with details about why the conclusions of that speaker may have been in error.
Open discussion, with details, makes for an atmosphere where the truth may come into open view. So why did two chairmen of the Western Pacific Geophysics Meeting in Singapore delete one of the oral-presentation reports from their official website? They gave no warning to the Paleochronology group.
A trio of geologists has published what they called the first successful direct dating of dinosaur bone. They used a new laser technique to measure radioisotopes in the bone.
Cold Warrior 8, posts 4. Wow, this one’s a peach. Fraudster, liar, and charlatan. It’s worth going to the site for several reasons. First, there’s a very nice picture of some dinosaurs, although regrettably there are no humans playing with them. Second, you’ll note it’s not really a “journal,” but rather a one page blog with several loosely related items.
Third, there’s no author associated with any of the articles. Upon reading the text, it appears that Mr. Hugh Miller, BS in Chemistry, is the author. One wonders if he’s related to Mr. The site also corrects some of the formatting issues that challenge the OP. On to the content of the first “article” which is the one in the OP. It references a number of dinosaur bones that were submitted for C dating and returned dates of less than 50, yo. This is incredibly dishonest as even the author admits, although he seems to have an imagined reason why it is not.
