Along with their collection of insects to look at under microscopes we had our own collection of small fossils to view. This was a whole-school day and the organizers estimated about pupils attended the event. With teaching staff, helpers and organizers the estimate was about people on site during the day. Also inside the house were Timetaxi. We thank the Geological Society of London for providing a grant to pay for a wide-format pop-up projection screen which was used throughout the week to project images from our high-definition microscope. An early morning start at Dinosaur Isle Museum saw the Landrover loaded up with a model dinosaur which had to be taken apart first and various small and very large and heavy fossils. This was taken by car-ferry to Hampshire. Stopping off first at the University of Portsmouth to collect some more large fossils we then drove on to the installation in the Cathedral.

‘Incredibly rare’: Dinosaur blood, feathers found in ancient amber

Needless to say, this shocking discovery is once again going to have paleontologists scrambling to find a way to prop up the popular myths that they have been promoting. What they have been telling us simply does not fit the facts. The truth is that this latest find is even more evidence that dinosaurs are far, far younger than we have traditionally been taught.

Once upon a time, scientists believed that it would be impossible to find anything other than the hardened fossilized remains of extinct dinosaurs. But instead, we are now starting to find dinosaur soft tissue all over the place. Fossils include complete or nearly-complete skeletons associated with preserved soft tissues such as feathers, fur, skin or even, in some of the salamanders, external gills.

Subsequent studies found tissue and cells in other dinosaur and reptile fossils.8 Besides collagen, proteins such as actin and myosin were also found.9 These additional discoveries helped verify the authenticity of the dinosaur tissue, and undercut the arguments of contamination.

It was big news indeed last year when Schweitzer announced she had discovered blood vessels and structures that looked like whole cells inside that T. The finding amazed colleagues, who had never imagined that even a trace of still-soft dinosaur tissue could survive. After all, as any textbook will tell you, when an animal dies, soft tissues such as blood vessels, muscle and skin decay and disappear over time, while hard tissues like bone may gradually acquire minerals from the environment and become fossils.

Schweitzer, one of the first scientists to use the tools of modern cell biology to study dinosaurs, has upended the conventional wisdom by showing that some rock-hard fossils tens of millions of years old may have remnants of soft tissues hidden away in their interiors. And the new findings might help settle a long-running debate about whether dinosaurs were warmblooded, coldblooded—or both.

They claim her discoveries support their belief, based on their interpretation of Genesis, that the earth is only a few thousand years old. Growing up in Helena, Montana, she went through a phase when, like many kids, she was fascinated by dinosaurs. In fact, at age 5 she announced she was going to be a paleontologist. But first she got a college degree in communicative disorders, married, had three children and briefly taught remedial biology to high schoolers.

Did Humans Walk the Earth with Dinosaurs? Triceratops Horn Dated to 33,500 Years

The Radiometric Dating Game Radiometric dating methods estimate the age of rocks using calculations based on the decay rates of radioactive elements such as uranium, strontium, and potassium. On the surface, radiometric dating methods appear to give powerful support to the statement that life has existed on the earth for hundreds of millions, even billions, of years. We are told that these methods are accurate to a few percent, and that there are many different methods.

dinosaur soft tissue carbon dating. Researchers have found a reason for the puzzling survival of soft tissue c dating of multiple samples of bone from 8 dinosaurs found in.

The other groups mentioned are, like dinosaurs and pterosaurs, members of Sauropsida the reptile and bird clade , with the exception of Dimetrodon which is a synapsid. Definition Triceratops skeleton, Natural History Museum of Los Angeles County Under phylogenetic nomenclature , dinosaurs are usually defined as the group consisting of the most recent common ancestor MRCA of Triceratops and Neornithes , and all its descendants.

In traditional taxonomy, birds were considered a separate class that had evolved from dinosaurs, a distinct superorder. However, a majority of contemporary paleontologists concerned with dinosaurs reject the traditional style of classification in favor of phylogenetic taxonomy; this approach requires that, for a group to be natural, all descendants of members of the group must be included in the group as well.

Birds are thus considered to be dinosaurs and dinosaurs are, therefore, not extinct. Norman, and Paul M. Barrett in suggested a radical revision of dinosaurian systematics. Phylogenetic analysis by Baron et al. They resurrected the clade Ornithoscelida to refer to the group containing Ornithischia and Theropoda. Dinosauria itself was re-defined as the last common ancestor of Triceratops horridus , Passer domesticus , Diplodocus carnegii , and all of its descendants, to ensure that sauropods and kin remain included as dinosaurs.

Using one of the above definitions, dinosaurs can be generally described as archosaurs with hind limbs held erect beneath the body. Other groups of animals were restricted in size and niches; mammals, for example, rarely exceeded the size of a domestic cat, and were generally rodent-sized carnivores of small prey.

Controversial T. Rex Soft Tissue Find Finally Explained

Here, RSR presents the scientific journals reporting, the kinds of biological material found so far, and the dinosaurs yielding up these exciting discoveries: Dinosaur and Dinosaur-Layer Creatures: As you view the exciting scientific discoveries below in this chronological catalog, please feel free to listen to Real Science Radio co-hosts Fred Williams and Bob Enyart observe their annual tradition of presenting dinosaur soft tissue and other amazing discoveries including short-lived left-handed amino acids , DNA , and Carbon 14 , all in bones and other specimens from dinosaur-layer Mesozoic and even deeper strata.

Soft tissue and amino acids should last only a fraction of that time. Someone who believes the Earth is less than 10, years old may see Schweitzer’s find as compelling evidence for a young Earth rather than a cause to re-examine the nature of fossilization.

The four types of fossils are: There are six ways that organisms can turn into fossils, including: More rarely, fossils have been found of softer body tissues. Bones – these fossils are the main means of learning about dinosaurs. The fossilized bones of a tremendous number of species of dinosaurs have been found since , when the first dinosaur bone was discovered.

Teeth and Claws – Sometimes a bit of a broken tooth of a carnivore is found with another dinosaur’s bones, especially those of herbivores. Lots of fossilized teeth have been found, including those of Albertosaurus and Iguanodon. Eggs , Embryos , and Nests – Fossilized dinosaur eggs were first found in France in Many fossilized dinosaur eggs have been found, at over sites. Sometimes they have preserved parts of embryos, which can help to match an egg with a species of dinosaur.

The embryo also sheds light on dinosaur development. The nests and clutches of eggs tells much about dinosaurs’ nurturing behavior.


Description Size in green compared with selected giant theropods Tyrannosaurus rex was one of the largest land carnivores of all time; the largest complete specimen, located at the Field Museum of Natural History under the name FMNH PR and nicknamed Sue , measured Historically average adult mass estimates have varied widely over the years, from as low as 4.

The forelimbs had only two clawed fingers, [22] along with an additional small metacarpal representing the remnant of a third digit. 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. But in other respects Tyrannosaurus’s skull was significantly different from those of large non- tyrannosauroid theropods.

Feb 16,  · Dr. Mary Schweitzer while doing research, accidentally discovered dinosaur soft tissue in a T-rex bone dated 67 million yrs old, which all textbooks say is : Open.

Tweet NaturalNews A recent archaeological discovery that throws a wrench into the conventional theory of evolution has reportedly cost a California professor his job. Mark Armitage, a former scientist at California State University, Northridge CSUN , was reportedly fired after claiming to have unearthed a dinosaur fossil that still contains soft, flexible tissue, suggesting that it can’t be millions of years old. A year veteran in his field, Armitage has published many studies over the years in peer-reviewed journals.

One of his most recent was published last July, pertaining to a discovery he made at the Hell Creek Formation excavation site in Montana. According to The Christian Post, Armitage was evaluating a triceratops horn fossil when he came across preserved soft tissue. A lawsuit recently filed in Armitage’s defense describes his reaction to the discovery as “fascinated,” since flexible matter has never before been discovered on a dinosaur fossil.

Naturally, Armitage published his findings — in this case, he published them in the Elsevier journal Acta Histochemica — and proceeded to share his findings with his students. Not long after, Armitage was approached by a CSUN faculty head who reportedly shouted at him, “We are not going to tolerate your religion in this department! This should be a wakeup call and warning to the entire world of academia.

Part of the Explore the Film series. “Clearly this is in violation of the dating process. It challenges the entire dating process.” – Kevin Anderson, Microbiologist at Van Andel Creation Research Center In , soft tissue was discovered inside the femur of a dinosaur bone by Dr. Mary Schweitzer.

One of the scientists who found the tissue and published a paper on it in the peer-reviewed literature 1 Mark Armitage was subsequently fired from his position at California State University Northridge. He has sued the university , claiming that he was fired because of his religious views. Instead, this update is about the fossil itself. Samples from the fossil were sent to Dr. I wanted the soft tissue that was found in the fossil to be dated, but it was not.

According to a report in the journal Radiocarbon, bioapatite is actually preferable to soft tissue in many cases. As the report states:

If the source of the carbon was mosasaur tissue (and this is the most straightforward explanation), then the mosasaur’s carbon date would be in line with an age of thousands of years, as inferred by the integrity of its soft tissue.

Evolution Before about it was widely thought that distinctively hominin fossils could be identified from 14 to 12 million years ago mya. However, during the s geneticists introduced the use of molecular clocks to calculate how long species had been separated from a common ancestor. The molecular clock concept is based on an assumed regularity in the accumulation of tiny changes in the genetic codes of humans and other organisms.

Use of this concept, together with a reanalysis of the fossil record, moved the estimated time of the evolutionary split between apes and human ancestors forward to as recently as about 5 mya. Since then the molecular data and a steady trickle of new hominin fossil finds have pushed the earliest putative hominin ancestry back in time somewhat, to perhaps 8—6 mya.

Possible pathways in the evolution of the human lineage. Announced in , this specimen is dated to the period between 7 and 6 mya. The distinctive mark of Hominini is generally taken to be upright land locomotion on two legs terrestrial bipedalism. The skull of S. The most remarkable aspect of this skull is the broadness and flatness of its face—something previously associated with much more recent hominins—in conjunction with a smaller, ape-sized braincase. This specimen also has small canine teeth compared with those of apes, thus aligning it with the hominins in an important functional regard.

Sahelanthropus, then, emphasizes an evolutionary pattern that seems to have been a characteristic of the tribe Hominini from the very start—a pattern that aligns it with what is observed in most other evolutionarily successful groups of mammals. Human evolution, it appears, has consistently been a process of trial and error.


My cat used to drink from the garden pond and never seemed to suffer any ill effects, and you often see dogs drinking from muddy puddles. So why do humans have to be so careful and only drink clean water? Will it form sediment that gets buried beneath the seabed and eventually turns into plastic “oil” or “coal”?

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.

An Update On The Triceratops Fossil That Contained Soft Tissue

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.

* More Soft Dinosaur Tissue, Now from an “80 Million” Year Old Hadrosaur: Consistent with the expectations of biblical creationists, according to Nat’l Geographic, there’s yet another discovery of soft tissue in a dinosaur, this time, a hadrosaur, with soft blood vessels, connective tissue, and blood cell protein amino acid chains partially.

These are external links and will open in a new window Close share panel Image caption The feathered tail was preserved in amber from north-eastern Myanmar The tail of a feathered dinosaur has been found perfectly preserved in amber from Myanmar. The one-of-a-kind discovery helps put flesh on the bones of these extinct creatures, opening a new window on the biology of a group that dominated Earth for more than million years.

Examination of the specimen suggests the tail was chestnut brown on top and white on its underside. The tail is described in the journal Current Biology. The study’s first author, Lida Xing from the China University of Geosciences in Beijing, discovered the remarkable fossil at an amber market in Myitkina, Myanmar. The million-year-old amber had already been polished for jewellery and the seller had thought it was plant material.

On closer inspection, however, it turned out to be the tail of a feathered dinosaur about the size of a sparrow. Lida Xing was able to establish where it had come from by tracking down the amber miner who had originally dug out the specimen.
