Is there a bona fide scientific challenge to the age of the Earth, which is measured to be 4. As an old-earth creationist OEC , I would answer no.

The June 9, announcement of dinosaur soft tissue in Nature Thus far, no secular scientist has suggested C dating of these fossils since they believe.

A fossil from Classical Latin : fossilis , literally “obtained by digging” [1] is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons , stone imprints of animals or microbes , objects preserved in amber , hair, petrified wood , oil, coal, and DNA remnants. The totality of fossils is known as the fossil record.

Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ages of rocks and the fossils they host. There are many processes that lead to fossilization, including permineralization , casts and molds, authigenic mineralization , replacement and recrystallization, adpression, carbonization , and bioimmuration.

A fossil normally preserves only a portion of the deceased organism, usually that portion that was partially mineralized during life, such as the bones and teeth of vertebrates , or the chitinous or calcareous exoskeletons of invertebrates. Fossils may also consist of the marks left behind by the organism while it was alive, such as animal tracks or feces coprolites.

These types of fossil are called trace fossils or ichnofossils , as opposed to body fossils. Some fossils are biochemical and are called chemofossils or biosignatures. Permineralization is a process of fossilization that occurs when an organism is buried.

Hidden life revealed inside dinosaur bones

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.

Due to a huge amount of evidence suggesting that C would not yield numbers (other dating methods used on rock surrounding the bone primarily).

While at the Hell Creek Formation excavation site in Montana, researcher Mark Armitage discovered what he believed to be the largest triceratops horn ever unearthed at the site, according to attorney Brad Dacus of Pacific Justice Institute. The lawsuit against the CSUN board of trustees cites discrimination for perceived religious views. Armitage, a published scientist of over 30 years, was subsequently let go after CSUN abruptly claimed his appointment at the university of 38 months had been temporary, and claimed a lack of funding for his position, according to attorneys.

This should be a wakeup call and warning to the entire world of academia. She could not comment on the lawsuit as university officials had not yet received the complaint. It is imperative that we crush this guy. We cannot allow new discoveries to impact established science. He should be laughed out of his job, not fired with malice. There is still the issue of soft tissue on it.

Would you ignore it because it goes against your evolutionary take on dinosaurs?

Does Dinosaur Tissue Challenge Evolutionary Timescales? A Response to Kevin Anderson, Part 1

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.

A fossil is any preserved remains, impression, or trace of any once-living thing from a past The development of radiometric dating techniques in the early 20th century allowed has been the discovery of soft tissue in dinosaur fossils, including blood vessels, and the isolation of proteins and evidence for DNA fragments.

One of the tricks you learn hunting dinosaurs in Canada is to look for orange. Dinosaur bones are dull browns, tans, and greys. But in the middle of the drab sandstones of the badlands—a dry landscape where wind and water have worn away much of the rock—you’ll sometimes catch a flash of fluorescent orange. Walk over and you may well find a dinosaur bone weathering out.

The orange is lichen, growing on the bone. The bone gives the lichen a stable foothold in the eroding landscape, it’s porous, storing moisture during droughts, and full of minerals like phosphate, vital to a growing lichen. It’s strange to think that something that died 76m years ago plays a role in modern ecosystems, but life is opportunistic.

Life exists almost everywhere on Earth.

Carbon-14 in Dinosaur Bones Challenges Evolution Theory and Supports Genesis Flood Account

It can’t be millions of years! Its from a global flood! Eggs have been found all over the world, up to Myr. Some dinosaur embryos have been detected by CAT scans and other Xray techniques.

Since , several samples of ostensibly soft tissue, such as blood teeth and eggshells from vertebrates dating from the Late Triassic to.

Over the past three years, ICR News has featured over 20 cases of original soft tissues found in fossilized remains around the world. Careful chemical analyses published in peer-reviewed journals concluded that original tissues—most often protein that had not mineralized—came from the buried animals’ carcasses.

But many of these studies relied on only a few different detection methods. Now, a team of researchers using special equipment at the MAX-lab in Lund, Sweden, has applied more than six different techniques to verify that tissues from inside a Cretaceous mosasaur humerus bone, which was kept in the Royal Institute of Natural Sciences of Belgium “for many years,” consist of mosasaur and not microbial molecules. First, the investigators chemically removed the mineral matrix from the mosasaur bone, leaving behind the proteins and other biomolecules.

Using scanning electron microscopy, they photographed what resembled actual protein fibers. This result was the same as that of a electron microscope study of mummified Tyrannosaurus rex bone. Using transmission electron microscopy, the investigators found that the fibers looked like recent bone proteins.

Carbon Dating of ’70 Million Year Old’ Mosasaur Soft Tissues Yields Surprising Results

Their findings demonstrate that previous claims showing the preservation of keratin protein in dinosaur fossils are likely to be false. Similarly, widely publicised claims of dinosaur blood in fossil bones were shown to likely represent an artefact of degraded organic matter rather than actual blood cells. The researchers undertook experimental treatments that either used microbes to decay tissues or subjected tissues to intense heat and pressure — a process known as maturation — in order to mimic the conditions a fossil experiences deep underground.

Evan Saitta from the University of Bristol’s School of Earth Science, led the research which has been published in the journal Palaios. He said: “Decay and mild maturation resulted in some intriguing textural differences in degradation patterns based on the type of keratin such as curling versus crimping of filaments when matured. In another experiment the vacuum conditions of an electron microscope appear to have produced folds, pits and blebs in a sample of degraded turkey skin, similar to those features previously suggested to represent dinosaur blood cells.

Regardless of ubiquitous, ancient stories and artifacts that indicate man once coexisted with dinosaurs see Butt and Lyons , ; Lyons , , evolutionists continue to put their confidence in assumption-based dating methods, declaring dinosaur fossils to be many millions of years older than man or monkey. Mary Schweitzer and her colleagues reported the find in Science magazine, describing the demineralized T. Amazingly, the researchers were even able to squeeze round, dark-red-to-deep-brown microscopic structures from the presumed T.

Scientists were shocked! Scientists have excavated a Tyrannosaurus and a hadrosaur from Montana, a Titanosaurus from Madagascar, and more samples that the famous dinosaur fossil hunter Jack Horner has uncovered in Montana, as well as Mongolia. Regarding the hadrosaur specimen found in Montana, Dr. Suggesting that these bones sat around for at least 70 million years or If soft, flexible, resilient, highly fibrous dinosaur tissue in many different specimens will not convince the gainsayer, what would?

New research challenges notion that dinosaur soft tissues still survive

Recovery of still-soft tissue structures, including blood vessels and osteocytes, from dinosaur bone after demineralization was reported in and in subsequent publications. Despite multiple lines of evidence supporting an endogenous source, it was proposed that these structures arose from contamination from biofilm-forming organisms. To test the hypothesis that soft tissue structures result from microbial invasion of the fossil bone, we used two different biofilm-forming microorganisms to inoculate modern bone fragments from which organic components had been removed.

Dinosaur fossils, it was long thought, are simple objects. The fossilization process leaves the overall shape of a dinosaur’s bones intact, but all.

Scientists agree on one aspect of Mary Schweitzer’s research. The tissues she found shouldn’t have been there, at least according to basic concepts of fossilization. Because of this, critics assert that what Schweitzer really found was a contaminated sample, not a breakthrough. Over 65 million years, there’s plenty of time for other life forms to contaminate the bones of a dinosaur. Fossils also come into contact with human and other tissues during excavation.

This presents a challenge for researchers trying to prove that a cell , tissue sample or DNA strand came from a specific extinct animal. After Schweitzer’s first paper appeared in Science, some critics suggested that she published it before conducting enough analysis. Schweitzer agreed with this claim at least in part.

She explained that the team published its findings as step to securing funding for later work [source: Yeoman ].
