Creation vs. Evolution

Jack Cuozzo click to enlarge. It was taken by the author in Bernifal Cave, one of the caverns in France that is renowned for Neanderthal art. Mammoth drawings are not unusual in such cave art, but the depiction of an apparent theropod dinosaur is remarkable.

The rejection of dating by religious fundamentalists is easier for them to make, but harder for them to demonstrate. The fossils occur in regular sequences time after time; radioactive decay happens, and repeated cross testing of radiometric dates confirms their validity.

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.

The Fossil Record

Recent Fossils Grand Canyon has so much more than pretty scenery. It contains an amazing diversity of rock formations with an abundance of fossils hidden within. The sedimentary rocks exposed throughout the canyon are rich with marine fossils such as crinoids, brachiopods, and sponges with several layers containing terrestrial fossils such as leaf and dragonfly wing impressions, and footprints of scorpions, centipedes, and reptiles.

Ancient fossils preserved in the rock layers range from algal mats and microfossils from Precambrian Time 1, million to million years ago to a multitude of body and trace fossils from the Paleozoic Era million years ago.

About. Located in South Jersey, the cradle of dinosaur paleontology, the park in Mantua Township, N.J., contains thousands of fossils dating back 65 million years.

How might the Hastings area have looked million years ago? Introduction Hastings is a large town and borough on the coast of East Sussex in Southern England with a population of over 86, people. Immediately east of the town and extending for four miles towards Fairlight are a series of spectacular golden coloured cliffs that tower over metres above sea-level.

In recent centuries many fine fossils have been exposed within the cliffs and foreshore, including the skeletal remains of dinosaurs, pterosaurs and fish, and other creatures and vegetation that inhabited this environment around million years ago mya. The sandstone rocks and fossils provide evidence of a large lake or lagoon, rich in aquatic and land based life, including several species of herbivorous plant eating and carnivorous meat eating dinosaurs.

Although dinosaur bones are relatively rare the evidence of these reptiles movements can be found more commonly in the form of footprints and casts on the surface of fallen rocks. Parking is available east of the town along Rock-a-Nore Road. View from the car park area overlooking the cliffs east of Hastings. Access to the cliffs and foreshore is made from Rock-a-Nore road, along which ‘pay and display’ parking is available throughout the year see above-left.

So, how do we know how old a fossil is? There are two main methods determining a fossils age, relative dating and absolute dating. Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.

Relative Dating The majority of the time fossils are dated using relative dating techniques. Using relative dating the fossil is compared to something for which an age is already known.

Stefen Chow Smithsonian Magazine Subscribe December In a pine forest in rural northeastern China, a rugged shale slope is packed with the remains of extinct creatures from million years ago, when this part of Liaoning province was covered with freshwater lakes. Volcanic eruptions regularly convulsed the area at the time, entombing untold millions of reptiles, fish, snails and insects in ash.

I step gingerly among the myriad fossils, pick up a shale slab not much larger than my hand and smack its edge with a rock hammer. A seam splits a russet-colored fish in half, producing mirror impressions of delicate fins and bones as thin as human hairs. It was in that Zhou and colleagues announced the discovery of a fossil from this prehistoric disaster zone that heralded a new age of paleontology. The fossil was a primitive bird the size of a crow that may have been asphyxiated by volcanic fumes as it wheeled above the lakes all those millions of years ago.

They named the new species Confuciusornis, after the Chinese philosopher. Until then, only a handful of prehistoric bird fossils had been unearthed anywhere in the world. That’s partly because birds, then as now, were far less common than fish and invertebrates, and partly because birds more readily evaded mudslides, tar pits, volcanic eruptions and other geological phenomena that captured animals and preserved traces of them for the ages. Scientists have located only ten intact fossilized skeletons of the earliest known bird, Archaeopteryx, which lived at the end of the Jurassic period, about million years ago.

Zhou, who works at the Institute of Vertebrate Paleontology and Paleoanthropology IVPP of the Chinese Academy of Sciences in Beijing, believed that the extraordinary bone beds in Liaoning might fill in some of the many blanks in the fossil record of the earliest birds. He couldn’t have been more prophetic.

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.

How might the Lyme Regis area have looked million years ago? The rocks date predominantly from the Early Jurassic epoch, approximately million years ago, during which time a warm sea spread across much of the UK. The famous coastline has yielded a range of spectacular fossils, including: The volume and quality of finds over the past two centuries in particular, have made Lyme Regis one of the most famous fossil locations in the world.

Discovering Fossils event participants admire a small ammonite. A pyritised ammonite – Eoderoceras armatum, from the foreshore. Parking is available in several car parks within Lyme Regis and also at the neighbouring village of Charmouth for visitors planning to walk between the two locations ; a local taxi and bus service are available, but fast walkers may prefer to travel the return journey on foot.

Lyme Regis was thrust into the limelight in , when a number of significant marine reptile remains were discovered by local fossil collectors Mary Anning and her brother Joseph Anning. Among their finds include the first recognised complete ichthyosaur skeleton, the skull of which was found by Joseph, and the rest of the skeleton by Mary soon after. Today, fossils can still be found and collected in large numbers on the beach and from the leading edge of the slumping clays along the coastline.

The best time to fossil hunt is on a falling tide, as fossils are re-deposited on the foreshore by the retreating sea.

Radiometric Dating and the Geological Time Scale

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. The earliest stromatolite of confirmed microbial origin dates to 2.

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.

Ancient Dinosaur Depictions

January Fossils provide a record of the history of life. Smith is known as the Father of English Geology. Our understanding of the shape and pattern of the history of life depends on the accuracy of fossils and dating methods. Some critics, particularly religious fundamentalists, argue that neither fossils nor dating can be trusted, and that their interpretations are better.

Other critics, perhaps more familiar with the data, question certain aspects of the quality of the fossil record and of its dating. These skeptics do not provide scientific evidence for their views.

One genus of stromatolite very common in the geologic record is Collenia. The earliest stromatolite of confirmed microbial origin dates to 2. The most widely supported explanation is that stromatolite builders fell victims to grazing creatures the Cambrian substrate revolution , implying that sufficiently complex organisms were common over 1 billion years ago.

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.

The waters rose and increased greatly on the earth, and the ark floated on the surface of the water. They rose greatly on the earth, and all the high mountains under the entire heavens were covered. The waters rose and covered the mountains to a depth of more than twenty feet.

Every living thing that moved on the earth perished–birds, livestock, wild animals, all the creatures that swarm over the earth, and all mankind. Everything on dry land that had the breath of life in its nostrils died. Every living thing on the face of the earth was wiped out; men and animals and the creatures that move along the ground and the birds of the air were wiped from the earth.
