10 Recent Discoveries That Explain Prehistoric Questions

10 Recent Discoveries That Explain Prehistoric Questions

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.

Scientists have known titanosaurs for a while, but this is a new species and even a new genus, which is a larger grouping, Pol said. Another titanosaur called Argentinosaurus was previously thought to be the largest. Around North Korean art performers in matching red coats and fur hats left for the South, its state media said on February 6, the latest in the flurry of cross-border exchanges in the run-up to the Pyeongchang Olympics.

Neovenator salerii (pronounced ‘knee-oh-vena-tour’ ‘sall-air-ee-eye’) is a large bodied theropod dinosaur. The genus name Neovenator comes from ‘New hunter’, and the species name from that of the Salero family who owned the land from which the first important dinosaur remains were found. Since it was first found it has given its name to a new group of dinosaurs called the.

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. Keep Reading Below Usually, atoms have an equal number of protons and neutrons. If there are too many or too few neutrons, the atom is unstable, and it sheds particles until its nucleus reaches a stable state.

Think of the nucleus as a pyramid of building blocks.

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.

How might the Fairlight area have looked million years ago? Introduction Fairlight is a small village located a short distance from the coast between Pett Level half a mile to the north-east and Hastings 4 miles to the south-west. Over the years coastal erosion has consumed much of the village outskirts and several homes have already toppled over the cliff. A recent study revealed the cliffs had retreated over metres in the last century alone. Until recently Fairlight was unprotected from the sea, but in the early s a project to construct a wave barrier was completed see below-right.

Today, erosion remains a big problem for the local inhabitants, but is now confined to the stretches either side of the barrier and the foreshore immediately in front of it. An abandoned house stands precariously close to the cliff edge. The cliffs at Fairlight Cove are now shielded by a large wave barrier. The cliffs and foreshore are comprised of layers of sandstone and clay, deposited during the Early Cretaceous epoch, approximately million years ago mya.

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. See below and on our Carbon 14 dating page. Not only has dinosaur blood blood vessels, and collagen been found and confirmed by the whole scientific community, now fragments of collagen and iron rich proteins have been found within the walls of blood vessels. Scientists descrribe it as a “startling find” especially since the dinosaur bone it was found in was reported to be million years old. Dinosaur organic matter found Imagine the impossibility of a dinosaur bone not turning to stone, not decaying and crumbling to dust and the contents inside the bone surviving.

What is involved would be million years of summer, winter, rain, snow, droughts, floods, earthquakes, crustal movement, perhaps a million or more of these events and yet this bone with its organic matter is still there. A few years ago scientists worldwide agreed that no organic material could ever survive beyond thousands of years.

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.

Dinosaur fossils have been found on every continent on Earth; humans have inhabited, and continue to inhabit, every continent on Earth. Thus, it would seem that if dinosaurs and humans really did live as contemporaries at one time, as creationists contend, human fossils would have been found alongside, near, or in the same strata as dinosaur fossils.

Paul gave lower estimations of 9. The praemaxilla has an upward branch excluding the maxilla from the bony nostril. The neural spines on the rear dorsal, sacral and front tail vertebrae are expanded in side view.

The upper corners of the humerus are robust. The humerus has a boss above the condyle that contacts the radius, that is hook-shaped.

These formations may have resulted from carcass burial in an anoxic environment with minimal bacteria, thus slowing decomposition. Stromatolites Lower Proterozoic stromatolites from Bolivia , South America Stromatolites are layered accretionary structures formed in shallow water by the trapping, binding and cementation of sedimentary grains by biofilms of microorganisms , especially cyanobacteria.

While older, Archean fossil remains are presumed to be colonies of cyanobacteria , younger that is, Proterozoic fossils may be primordial forms of the eukaryote chlorophytes that is, green algae. One genus of stromatolite very common in the geologic record is Collenia.

Then, two weeks after publishing his findings, he was fired. Now California State University at Northridge has paid Armitage a six-figure sum to settle his wrongful termination suit based on religious discrimination. The case of Armitage is the latest to show the mounting hostility Christians face in academics and other public arenas. The whole discussion of evolution ends if you show that the earth is young.

You can just erase evolution off the whiteboard because of soft tissue in dinosaur bones. He had published some 30 articles in scientific journals about his specialty. In May , Armitage went on a dinosaur dig at the famous fossil site of Hell Creek in Montana, where he unearthed the largest triceratops horn ever found there. Back at CSUN, he put the fossil under his microscope and made the startling discovery: If the dinosaur were 65 million years old, the soft tissue could not have possibly remained, he says.

His findings seconded groundbreaking discoveries by noted molecular paleontologist Mary Schweitzer , who triggered an earthquake in the world of paleontology when she published about soft tissue in dinosaur bones in Schweitzer subsequently postulated that iron is responsible for preserving the soft tissue. Two week later, he found himself without a job. Professors and students alike had praised his work managing the microscope lab.

His suit alleged he was excluded from a secret meetings of the microscopy committee.

It had a big head 4. It had 17 inch 43 cm long spikes extending from its vertebrae along the neck and tail that may have formed a thick, fleshy sail on its back. It had powerful arms and each hands had three fingers, each equipped with long, sickle-like claws. It weighed roughly tons Acrocanthosaurus lived during the early Cretaceous period , roughly million million years ago in the tropics near sea level in what is now Oklahoma, Texas, and Utah, USA.

A dinosaur found on the Isle of Wight has travelled 6, miles across the world as part of a special exhibition in Japan. The fossilised bones of the meat eating Neovenator, including parts of the skull and feet, are featured in a new exhibition at the Fukui Prefecture Dinosaur Museum’s exhibition – Theropods: from Carnivorous Dinosaurs to Flying Birds.

Share12 Shares Science long ago established that dinosaurs are awesome. However, any seemingly tiny discovery, at any time, can radically change our understanding of the past. We mammals, along with birds, are endotherms and we keep ourselves warm through metabolic processes—an energetically expensive survival strategy. However, it allows us to live across a range of environments.

Ectotherms, such as reptiles, have poor internal heating mechanisms—they expend less energy, but suffer the inconvenience of having to sun themselves for warmth. Kind of—but no, not really. Scientists have recently found that they belonged to a weird separate class of reptile, and were neither warm-blooded nor cold-blooded. In fact, they fell right smack-dab in the middle of the metabolic spectrum, quite unlike any other living creature. Analyzing a range of bones allowed for an estimation of growth rates, and from that the team at UNM inferred metabolic rates and whether the animal was warm-blooded or cold-blooded.

This middle-of-the-road metabolism gave dinosaurs an exploratory advantage: They required fewer calories than similarly sized mammals and were vastly more mobile than other reptiles, such as crocodiles. However, fossilized remnants from a Labrador-sized individual with a 1.

DISCOVERING FOSSILS

See Article History Alternative Title: Dinosauria Dinosaur, the common name given to a group of reptiles , often very large, that first appeared roughly million years ago near the beginning of the Middle Triassic Epoch and thrived worldwide for nearly million years. Most died out by the end of the Cretaceous Period , about 66 million years ago, but many lines of evidence now show that one lineage evolved into birds about million years ago.

The English anatomist Richard Owen proposed the formal term Dinosauria in to include three giant extinct animals Megalosaurus , Iguanodon , and Hylaeosaurus represented by large fossilized bones that had been unearthed at several locations in southern England during the early part of the 19th century. Owen recognized that these reptiles were far different from other known reptiles of the present and the past for three reasons: Originally applied to just a handful of incomplete specimens, the category Dinosauria now encompasses more than generic names and at least 1, species, with new names being added to the roster every year as the result of scientific explorations around the world.

A fossil (from Classical Latin fossilis; literally, “obtained by digging”) is any preserved remains, impression, or trace of any once-living thing from a past geological es 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.

These are identified by the catalogue numbers MIWG. After the extensive research work on specimen MIWG. Mention of Neovenator was made in in the Field Guide – Dinosaurs of the Isle of Wight by Martill and Naish, and then there was a long gap during which an almost-forensic analysis of the bones was carried out. Other researchers have been studying the features that may give clues as to its relationship with other dinosaurs the phylogeny and this resulted in the publication of two further papers — first in by Stephen Brusatte and Paul Sereno who placed Neovenator within the Carcharodontosauridae, and then in by Roger Benson, Matthew Carrano and Stephen Brusatte who established a new group for dinosaurs like Neovenator called the Neovenatoridae.

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.

The Christian Science Monitor reported this January that scientists found collagen, a protein basic to animal tissue, in an allegedly million-year-old fossil of a Lufengosaurus dinosaur in China.

A fossil bed in China that is being called “Jurassic Park” has yielded perhaps the greatest dinosaur soft tissue discovery of all time. According to media reports, “nearly-complete skeletons” have been discovered that even include skin and feathers.

The first 3 dinosaur fossils led to the recognition of a new group of animals, the dinosaurs. The first nearly-complete dinosaur skeleton in New Jersey spurs modern paleontology. People have been finding dinosaur fossils for hundreds of years, probably even thousands of years. The Greeks and Romans may have found fossils, giving rise to their many ogre and griffin legends.

There are references to “dragon” bones found in Wucheng, Sichuan, China written by Chang Qu over 2, years ago; these were probably dinosaur fossils. Much later, in , a huge thigh bone femur was found in England by Reverend Plot. It was thought that the bone belonged to a “giant,” but was probably from a dinosaur.

A report of this find was published by R.
