Carbon 14 is used for this example: This nullifies the carbon method as well as demonstrating that the earth is less than 10, years old. The above is offered as a simple fact of research. Knowing how faulty creationist “facts” can be, let’s do a little research of our own. One suspects that the scientific world would not be using the carbon method if it were so obviously flawed. Could it be that the whole scientific community has missed this point, or is it another case of creationist daydreaming? This argument was popularized by Henry Morris , p. In another creationist, Robert L. Whitelaw, using a greater ratio of carbon production to decay, concluded that only years passed since carbon started forming in the atmosphere!
University settles lawsuit with scientist fired after he found soft tissue in dinosaur bones
Or at least I thought so until Lucy poured out her heart. Well, I was wrong. This article is about the girls who are born on the mainland. She might look Chinese, but her values are Western. She might be Chinese, BUT
How radiometric dating works in general: Radioactive elements decay gradually into other elements. The original element is called the parent, and the result of the decay process is .
What about the fact that the “simple” organisms are buried in the lower levels and the more “complicated” ones are buried in the higher levels? Doesn’t this fact support the notion that simple organisms evolved into more and more complex organisms over time, with the more complex organisms buried and fossilized above the earlier and simpler life forms?
Certainly this seems like a very logical assumption. But, things just aren’t that easy. There are a number of potential problems with this interpretation of the fossil record. For example, it is interesting to note that some general kinds of fossilized creatures are very generally found in the same relative vertical orientation, with respect to each other in the fossil record, that they would have naturally been found in during life.
Single celled organisms make their first appearance in the lowest layers followed by multicelled ocean bottom-dwelling creatures like sponges and worms etc. Higher up come creatures like bony fishes, then land plants and animals, then birds and larger land animals. Of course, this is a very general pattern and does not explain why certain creatures that lived on the bottoms of oceans, like trilobites, make their first appearance in the Cambrian Ma while other creatures that live on ocean bottoms, like crabs and lobsters, don’t appear until the beginning of the Cretaceous Ma.
If the geologic column truly represents a series of closely spaced catastrophic burial events instead of long ages of time, how can this feature be explained? Certainly this seems like a difficult and rather mysterious problem for those, like myself, who might think to question the long age notion of the fossil record. At least a partial explanation might be found in the fairly recently discovered fact that at least some nested hierarchical patterns to the distribution of different populations both living and within the fossil record seem to be strongly related to ecological and population-size factors.
This pattern arises when species that appear on few islands occur only on the islands with the most species, while only the most widespread species are found on the islands with few species Wright et al. The nested subset pattern arises because species differ in their distributions across space.

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.
Introduction. One of the evidences for a young earth that creationists have been using now for more than two decades is the argument about the influx of meteoritic material from space and the so-called ‘dust on the moon’ problem.

Everything Worth Knowing About … Scientific Dating Methods
Everything Worth Knowing About Scientific Dating Methods This dating scene is dead. The good dates are confirmed using at least two different methods, ideally involving multiple independent labs for each method to cross-check results. Sometimes only one method is possible, reducing the confidence researchers have in the results. Methods fall into one of two categories: These methods — some of which are still used today — provide only an approximate spot within a previously established sequence:
Le substantif masculin , ,  dinosaure est emprunté , , par l’intermédiaire de l’anglais  dinosaur , au latin scientifique moderne dinosaurus , .. Le taxon Dinosauria a été introduit et défini par le paléontologue britannique Richard Owen en afin de regrouper une «tribu ou sous-ordre distinct de Reptiles Sauriens» .Le terme dérive de deux racines.
This 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. Dinosaur bones, on the other hand, are millions of years old — some fossils are billions of years old.
To determine the ages of these specimens, scientists need an isotope with a very long half-life. Some of the isotopes used for this purpose are uranium , uranium and potassium , each of which has a half-life of more than a million years. Unfortunately, these elements don’t exist in dinosaur fossils themselves. Each of them typically exists in igneous rock, or rock made from cooled magma.

We describe the first eggs from the St. Mary River Formation Maastrichtian of Montana. Abstract Two closely associated egg types occur at the same locality in the Upper Cretaceous Maastrichtian St. Mary River Formation in north central Montana. These specimens represent the first fossil eggs described from this formation.

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.

But how long does it take for the organic molecules we are made of to break down after death? In general, the longer the time from death, the larger the amount of decay that should be observed. This is particularly true for soft tissue, the parts of an organism that are not mineralized such as skin, muscles, or blood vessels. In , Mary Schweitzer, then affiliated with the Museum of the Rockies, shared data suggesting the possibility of soft tissue and biomolecules preservation in a bone of Tyrannosaurus rex supposedly 68 Ma old .
Her findings were met with great resistance and skepticism. Similar observations of blood vessels, collagen, and osteocytes from dinosaur bone had been published by Roman Pawlicki and his colleagues since  , but had not stirred much debate, probably because Jurassic Park, which popularized the subject, had not been written and filmed yet. In the last two decades, Mary Schweitzer and her group found additional examples and used a widening array of analytical techniques to document their findings [ ].
Consequently, the possibility of preservation of original dinosaur soft tissue and biomolecules is becoming more accepted, and this blog post reviews some of what has been published on the subject in the last year and a half. Dinosaur specimens with soft tissue preservation reported in Three different dinosaur skeletons, with bones in articulation or association, were described in the literature with special mention of or an emphasis on the presence of soft tissue.
The first, a ceratopsian ornithischian Psittacosaurus sp. The pigments are thought to represent original organic matter, more specifically melanin residues.
