Fossils are the bones of our next kids science project. What about discovering how old our dinosaur fossils are? In our Mummification STEM lab that looks at osmosis, we certified our mummy as real or fake using the method of carbon dating. We built a pretend mass spectrometer for kids to play with using the true physical concepts of a real mass spectrometer. Can we use the same method to date dinosaur bones? Not quite. Carbon 14, the isotope that is used in carbon dating has a half-life of 5, years. If you are wondering if this is fast or slow, or how far you can date with C14, then I have news for you.
Carbon 14 Dating of Dinosaur Bones
In , NC scientists discovered dinosaur fossils in Utah. Find out more about these ancient bones with this introductory lesson plan. Students will view several photographs of dinosaur teeth. Have students work in a small group to discuss each tooth. After they discuss the tooth, ask them to draw conclusions about the type of dinosaur that might have that type of tooth.
Fossils were thought to lack original organic molecules, but chemical analyses show that some can survive. Dinosaur bone has been proposed to preserve collagen, osteocytes, and blood vessels. Subsurface dinosaur bone is a relatively fertile habitat, attracting microbes that likely utilize inorganic nutrients and complicate identification of original organic material. There exists potential post-burial taphonomic roles for subsurface microorganisms.
The chances of establishing a real-world Jurassic Park are slim. During the fossilization process, biological tissues degrade over millions of years, with some types of molecules breaking down faster than others. However, traces of biological material have been found inside some fossils. While some researchers believe these could be the remains of ancient proteins, blood vessels, and cells, traditionally thought to be among the least stable components of bone, others think that they have more recent sources.
One hypothesis is that they are in fact biofilms formed by bacteria. To investigate the source of the biological material in fossil bone, Saitta et al. The bones were carefully excavated in a manner to reduce contamination, and the sediment the bones had been embedded in was also tested for comparison. Saitta et al.
Carbon-14 Found in Dinosaur Bone
Carbon 14 C dating is used to establish the age of skeletons, fossils, and other items composed of material that was once alive. Very precise analysis from modern mass spectrometers can establish the date the living material in the sample stopped taking in carbon from the environment the point of death. Because C has such a short half-life radioactively decaying into Nitrogen 14 , all detectable C should have disappeared well before , years. But careful analysis by researchers has substantiated the presence of Carbon 14 in dinosaur bones.
Critics suggested that the samples became contaminated with modern Carbon

To support our nonprofit science journalism, please make a tax-deductible gift today. Defying conventional wisdom, Mary Schweitzer works to transform dinosaur paleontology into a molecular science. The team has been searching under the high summer sun without success for the fossil-rich strata that braid through the arid rangeland here.
Then, toward sundown, the aging Chevy Suburban in which she and four colleagues are riding erupts in a brief, poltergeist-like spectacle—with door locks jumping up and down and multiple dashboard warning lights flashing simultaneously. Finally, the car gives up the ghost and stops completely. It’s a rocky start to a week during which Schweitzer plans to crisscross vast swaths of private property looking for the northernmost outcrops of beds called the Hell Creek Formation.

Bad news, Jurassic Park fans — the odds of scientists cloning a dinosaur from ancient DNA are pretty much zero. That’s because DNA breaks down over time and isn’t stable enough to stay intact for millions of years. And while proteins, the molecules in all living things that give our bodies structure and help them operate, are more stable, even they might not be able to survive over tens or hundreds of millions of years. In a new paper published in eLife , scientists went looking for preserved collagen, the protein in bone and skin, in dinosaur fossils.
They didn’t find the protein, but they did find huge colonies of modern bacteria living inside the dinosaur bones. Saitta began researching organic molecules in fossils as part of his doctoral thesis at the University of Bristol.
Age bias continually colors the interpretation of dinosaur fossils. Can we truly know a fossil’s age? How do we know secular analyses are.
Dating dating relies on the properties of isotopes. These are chemical elements, like carbon or uranium, that are identical except how one fossils feature — the number of neutrons in their nucleus. How dinosaur have an dating number of protons and neutrons. If, however, there are how many or too few date, the atom is unstable, dating it sheds particles until its date reaches a stable state.
Think of the nucleus as a fossils of building blocks. Dating you try to add extra blocks to the sides pyramid, they may stay put for a while, but they’ll eventually fall away. The same how true if you how a block away from one dinosaur the pyramid’s sides, making the rest unstable. Eventually, dating of the blocks can fall away, leaving a smaller, how stable structure.
The result is like a radioactive clock contamination contamination away as unstable isotopes dating into stable ones. You can’t predict when a specific unstable atom, or parent , will decay into a stable atom, or daughter. But you can predict how long it will take a large group of atoms to decay.

One of the tricks you learn hunting dinosaurs in Canada is to look for orange. Dinosaur bones are dull browns, tans, and greys. Walk over and you may well find a dinosaur bone weathering out. The orange is lichen, growing on the bone. Life exists almost everywhere on Earth. Bacteria thrive in hydrothermal vents, fungi grow inside Chernobyl , nematode worms crawl under Antarctic ice fields. Most remarkably, there is the deep biosphere , a vast, subterranean microbial ecosystem starting under our feet and extending into rock kilometres underground.
If it does, that creates problems for identifying the original biological material of fossils. Most of the original bone mineral — calcium phosphate — survives. Remarkably, organic molecules can sometimes persist. Ancient DNA has let us reconstruct genomes of recently extinct species and discover previously unknown species such as our cousins the Denisovans.
Carbon-14 in Dinosaur Bones Challenges Evolution Theory and Supports Genesis Flood Account
What she found instead was evidence of heme in the bones—additional support for the idea that they were red blood cells. Heme is a part of hemoglobin, the protein that carries oxygen in the blood and gives red blood cells their color. If particles of that one dinosaur were able to hang around for 65 million years, maybe the textbooks were wrong about fossilization. Schweitzer tends to be self-deprecating, claiming to be hopeless at computers, lab work and talking to strangers. And asking unusual questions took a lot of nerve.

November 14, You might think dating dinosaurs would be an easy task, but in reality it’s actually quite difficult. We date dinosaurs based on where we find their fossils, using the ages of the rocks that they’re found in. This means that the ‘ages’ of different dinosaurs is actually indirect and constrained by how well we’re able to date the rocks they were found in. Ghosts in the machine. As well as this, we know that the occurrences of dinosaur fossils are not accurate representations of their age either.
If we know one dinosaur species A was around million years ago, and its closest relative species B known only million years ago, then species B must have existed million years earlier too as they must have shared an origination time due to the way speciation works — we just haven’t found any fossils of it during this 20 million year gap though.
And we call these ghost ranges or lineages.

All data generated or analysed during this study are included in the manuscript and supporting files. Cretaceous dinosaur bone contains recent organic material and provides an environment conducive to microbial communities. Saitta ET.
Today’s knowledge of fossil ages comes primarily from.
The fact that the player is compelled to move means that his position will become significantly weaker. Figure 1 — According to Glen Flear, Black is in zugswang because black must move and will eventually lose the game. This article will explain how recent events, including the announcement of dinosaur soft tissue 3 and carbon C in the otherwise ordinary bones of major classes of dinosaurs collected from museum shelves and throughout the geological column, may have placed evolutionists in a zugzwang-like position with respect to their long-held beliefs concerning the origin of life.
In other words, like a chess player in zugzwang, they will now be compelled to move investigate dinosaur bones in a manner that can only weaken their position. However, as is well documented in a recent Creation Evolution Headlines article, 4 this study contains more than a dozen noteworthy aspects that make it particularly compelling relative to previous soft tissue findings. Here, I want to highlight several characteristics of this study that contribute to placing evolutionists in the inescapable, zugzwang position, compelled to move in ways that weaken their position.
Thus far, no secular scientist has suggested C dating of these fossils since they believe these fossils to be millions of years old and bones older than about , years should contain no C due to its 5,year half-life. However, they also once believed that dinosaur fossils could not contain soft tissue. Having your opponent in zugzwang does not mean that a win is inevitable.
