Dinosaur Fossils


See this page in: Hungarian , Russian , Spanish People who ask about carbon 14C dating usually want to know about the radiometric [1] dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years. People wonder how millions of years could be squeezed into the biblical account of history. Clearly, such huge time periods cannot be fitted into the Bible without compromising what the Bible says about the goodness of God and the origin of sin, death and suffering —the reason Jesus came into the world See Six Days? Christians , by definition, take the statements of Jesus Christ seriously. This only makes sense with a time-line beginning with the creation week thousands of years ago. It makes no sense at all if man appeared at the end of billions of years. We will deal with carbon dating first and then with the other dating methods. How the carbon clock works Carbon has unique properties that are essential for life on Earth.

Don’t get me wrong, I’m not really the target audience if I had to pick, I’d want the thrill of danger one can only get from a manticore , but still, it’s kind of a letdown.

Dating dinosaurs and other fossils Fossils themselves, and the sedimentary rocks they are found in, are very difficult to date directly. Instead, other methods are used to work out a fossil’s age.

An article in the January National Geographic boldly proclaimed: The evidence, however, reveals an entirely different story. Hubbard found elegant drawings of an elephant, an ibex, a dinosaur, and other animals. He stated concerning the dinosaur drawing: The fact that some prehistoric man made a pictograph of a dinosaur on the walls of this canyon upsets completely all of our theories regarding the antiquity of man The fact that the animal is upright and balanced on its tail would seem to indicate that the prehistoric artist must have seen it alive , pp.

Hubbard and his team of archaeologists discovered dinosaur tracks preserved in strata identified as Triassic—alleged by evolutionists to be more than million years old. How could Indians have known how to draw such a perfect picture of an animal the dinosaur that they never had seen or had described to them by someone who had seen it?

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

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.

The Age of Dinosaurs was so many millions of years ago that it is very difficult to date exactly. Scientists use two kinds of dating techniques to work out the age of rocks and fossils. The first method is called relative dating. This considers the positions of the different rocks in sequence (in.

This article has been cited by other articles in PMC. The Buntsandstein and Keuper each comprise predominantly continental siliciclastic strata, whereas the Muschelkalk is made up of carbonates and evaporites deposited in a shallow epicontinental sea. Later researchers used fossils of marine invertebrates to correlate carbonate units exposed along the northern and southern flanks of the European Alps with the Triassic strata in the Germanic Basin.

Starting in the late 19th century, geologists, mostly working in the Austrian Alps, established the global standard marine stages of the Triassic Period from oldest to youngest: The Scythian was later further divided into the Induan and Olenekian stages. Correlating continental and marine strata is always fraught with issues, and absolute age controls are essential for this purpose. In recent decades, improved methods of radiometric dating, especially uranium—lead U—Pb dating of detrital zircons, have led to the development of an increasingly robust chronostratigraphic framework for the Triassic 3.

The Triassic Period — Ma before present represents a critical time interval in the history of life 4. Many of the dominant present-day groups of animals and to a lesser extent plants or their close relatives first appeared in the fossil record during this period. One of these groups is the dinosaur—bird clade of archosaurian reptiles. The oldest undisputed dinosaurs are known from the early Late Triassic, about Ma 5 , 6.

This unexpected diversity indicates that the origin and initial evolutionary radiation of dinosaurs clearly predated the deposition of the Ischigualasto Formation. Its faunal assemblage became the quintessential example of a Middle Triassic vertebrate community from Gondwana 8. They also point out that there is otherwise little difference in faunal composition between the two assemblages, both of which are dominated numerically by nonmammalian synapsids cynodonts and dicynodonts.

The Age of Dinosaurs

At the end of the day, tissue is something organic and so it can be dated. I left the conversation on that topic with somebody linking to an article regarding the latest development of that topic. Coincidence or not, Mary Schweitzer and her team had recently published in article in which they explained that Iron may be the reason why the tissue has been preserved for so long http: And I have to say that until now I am still very much puzzled. The logic is that the lower strata are older than the younger strata, that I have no problem accepting; it makes sense.

After that I decided to probe the issue further and look up if no carbon dating had been done.

The most widely known form of radiometric dating is carbon 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.

Crocodiles are also descendants of mid-Triassic archosaurs. With that definition, the pterosaurs and several species of archosaurs narrowly miss out on being classified as dinosaurs. The pterosaurs are famous for flying through the Mesozoic skies on leathery wings and reaching the largest sizes of any flying animal that ever existed. Earliest dinosaurs[ edit ] The first known dinosaurs were bipedal predators that were metres 3.

Saturnalia may be a basal saurischian or a prosauropod. The others are basal saurischians. Eoraptor , an early saurischian , B Lesothosaurus , a primitive ornithischian , C Staurikosaurus Saurischia pelvis, D Lesothosaurus pelvis It is clear from this figure that early saurischians resembled early ornithischians, but not modern crocodiles. Saurischians are distinguished from the ornithischians by retaining the ancestral configuration of bones in the pelvis. Another difference is in the skull, the upper skull of the Ornithischia is more solid and the joint connecting the lower jaw is more flexible; both are adaptations to herbivory and both can already be seen in Lesothosaurus.

Saurischia[ edit ] Setting aside the basal Saurischia, the rest of the Saurischia are split into the Sauropodomorpha and Theropoda.

Asteroid Impact That Killed the Dinosaurs: New Evidence

China building boom uncovers buried dinosaurs, makes a star October 25, by Christina Larson In this Sept. The excavation, led by Xu, begun after construction crews erecting new apartment buildings accidentally uncovered dinosaur bones and other fossils, dating back million years. Like many fossil excavation sites in China, this one was discovered by accident. China’s rapid city building has churned up a motherlode of dinosaur fossils.

While bulldozers have unearthed prehistoric sites in many countries, the scale and speed of China’s urbanization is unprecedented, according to the United Nations Development Program. Perhaps no one has seized the scientific opportunity more than Xu Xing, a diligent and unassuming standard-bearer for China’s new prominence in paleontology.

Carbon Dating and Dinosaurs First, radiocarbon (14 C) dating has traditionally been done with assumptions outside the Biblical framework, namely this: Interpretations have been without any consideration for the possibility that the Flood of Genesis was an actual event.

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.

Fossils – What is a Fossil?

Carbon 14 is a short lived radioactive element with a half-life is only 5, years approximately. So using current technology, you could at the most, use it for objects that only went back 70, or so years. That having been said — surprisingly you do get dates for dinosaur bones supposedly millions of years old using Carbon However, it is possible to get carbon 14 dates for dinosaur bones, but the dates will shock you.

If you then compare it with historic data what you find that the further back you get in known history the more unreliable it becomes. What do we mean by that?

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.

Fossils – What is a Fossil? A Fossils are the remains and traces of ancient organisms. A cluster of fossil ammonites, an extinct cephalopod. The convention is that a fossil must predate recorded human history. While there is no defined date, typically something must be older than 10, years to be considered a fossil. The oldest fossils in the fossil record date from 3.

There are two main types of fossils; body and trace. Body fossils include the remains of organisms that were once living bones, shells, teeth, eggs, etc , while trace fossils are the signs that organisms were once present footprints, tracks, burrow, coprolites. Trace fossils represent a data source that reflects animal behaviors, and they do not require the preservation of hard body parts. Many traces date from significantly earlier than the body fossils of the animals suspected to have made them.

Lack of oxygen that limits decay and scavenging. Continued sediment accumulation 4. The absence of heat or compression which might destroy the fossil Fossils are most often preserved within sediments that were deposited in water, such as wetlands, river basins, or the ocean. Types of Fossilization Permineralization or Petrification – After an organism is buried, minerals carried by water such as silica, calcite or pyrite replace the organic material in the fossil.
