No. Non-avian dinosaurs were extinct about 65 million years ago, as the most recent dinosaur bone was directly dated as being 64.8 ± 0.9 Ma old. The second dinosaur bone sample from Paleocene strata just above the Cretaceous-Paleogene interface yielded a Paleocene U-Pb date of 64.8 ± 0.9 Ma, consistent with palynologic, paleomagnetic, and fossil-mammal ...

Yes, it is real. According to Snopes and the school is supposedly Blue Ridge Christian Academy in Landrum, South Carolina. There's also a second page linked on the site: (source) This is also confirmed by Answers in Genesis, a noted anti-science, pro-creationist website: Today, we bring your attention to another attack on Christian education. A Christian K–...

There are many reasons why this is wrong. The first one is the assumption of 1 supernova per 25 years. That was the value arrived at in Gustav Tammann's article published in 1970. Others got values up to 100 years (Tammann himself changed his value later). All these values are really only good guesses. Worse errors are made in the percentage of remnants ...

Has tuff found amongst the deposits at the Dinosaur National Monument? Yes. The most famous section of the rocks in Morrison Formation in Dinosaur National Monument, the Brushy Basin Member, is chock full of volcanic ash beds that have long since been converted to rock (1, 2, 3). It's also chock full of dinosaur fossils, which is what makes it so famous. ...

No they are clearly not very old homo sapiens. The hypothesis of Dr. Cuozzo completely fails to explain the following evidence (and more). Direct DNA evidence Neanderthal DNA has been mapped multiple times and it is distinguishable from Sapiens DNA. While it is clear that Neanderthals and Sapiens share a lot of DNA, it very evident from DNA sequencing that ...

According to a Nature article from 1998 this is true (or at least, was in 1998). Coelacanths were known for decades, but only as fossils. They appeared in the fossil record around 370 million years ago, had their heyday in terms of species diversity around 220 million years ago, and went into a long sunset that appeared to end with extinction, around 70 ...

There is a simple factual response based on the fossil record, "No. Dinosaurs and people did not coexist" but this does not really answer the question "did humans draw dinosaurs?" -- with the implicit assumption that the two coexisted. Here I will provide some commentary about cave drawings (petroglyph, pictogram) with sources for further reading. First a ...

Carbon dating has been extensively cross-referenced by tree-ring dating (dendrochronology). Carbon dates that are corrected by tree-ring dating are called calibrated. Tree-ring dating relies on the fact that trees have annual growth spurts and dormant period. As a result, each year the tree grows a new set of light and dark layers. These rings are easiest ...

It turns out that SN1987A did pretty much what I suggested. It had a ring of material that had been thrown off the star some 20,000 years ago. When the star exploded the light from the explosion illuminated this ring 8 months later. Simple measurements of the size of the ring and the known distance to SN1987A yield a speed of light that is the same as the ...

No, continental rocks are not the same as ocean floor. Continents are mostly made up of minerals like granite, which are lighter than ocean floor minerals like basalt (sima, short for Silicon/Magnesium). Continental material is mostly sial (short for Silicon/Aluminium) which is lighter. Partially molten mantle material is pushed up at mid-ocean ridges, ...

The figures are roughly confirmed by a different 2014 survey by Pew Research (Sample size = 35,071) : 33% believe "Humans and other living things have evolved due to natural processes such as natural selection" 25% believe "A supreme being guided the evolution of living things for the purpose of creating humans and other life in the form it exists today" ...

There is virtually no 14C in rocks more than a few hundreds of thousands of years old as 14C is radioactive with a half-life of only about 5,730 years. There is negligible 14C in fossil fuels (such as coal) for a start, which directly contradicts any claim that the 14C is the same in all strata. Addendum: While the article linked in the question states ...

TL;DR Here's the gist of my answer: Some physicists have been working for decades on theories involving a variable speed of light. These theories are not widely accepted within the physics community. Empirical measurements have placed strict constraints on some of the predictions. Even if the theories are correct, there's only significant change in the ...

The short answer: No The long answer: Also No Here is why this does not hold water: Until recently we were not able to extract soft tissues recently as in last 10 years. This is to the best of my knowledge but the first discovery of soft tissue in dinosaurs was about 10 years ago by Mary Schweitzer. Most of the tissue is very old and it would be ...

In addition to @hdhondt's answer (+1) The evidence for the existence of Pangea lies in the existence of matches between fossil records and rock formations in continents that are now thousands of miles apart, in addition to Wegener's observation that the (continental shelves) of the existing continents match quite closely like a jigsaw. If Pangea did not ...

The following articles suggest that dinosaurs breathed efficiently, like birds do still: which allowed them to cope with low oxygen levels that killed off other species. Note that some birds are able to breathe and fly at 20,000 feet, where the oxygen is lower (less than half sea-level pressure). BBC Earth - Did all dinosaurs breathe like birds? BIRDS ...

Known history Because the range of times which can be measured by radiocarbon dating overlap with known history, it can be cross-checked with known history established by other means. The original 1949 paper Age determinations by radiocarbon content: checks with samples of known age by J. R. Arnold and W. F. Libby measures the carbon-14 content of wood and ...

The blue whale is a larger animal than any dinosaur with similarly large nostrils (see below) and is also warm blooded. It seems to be able to breathe without any problems (including spontaneous combustion ;o), in an atmosphere with lower oxygen levels than in the Cretateous (see below), which suggests there isn't really any need for higher partial pressure ...

Nylon is an artificial polymer invented by Wallace Hume in Dupont. The nylon polymer or the linkages that bind the subunits together were not found in nature before 1935. By 1975, bacteria capable of hydrolyzing nylon found in waste water from nylon plants were discovered. Genes for hydrolyzing the artificial polymer nylon could not have been present from ...

Gene duplication is a very important way of creating new genes and hence it helps organisms to evolve. Once a gene is duplicated, the "spare" copy of the gene is effectively not needed by the cell, as the original still does the required job. This leaves the copy free to mutate in whatever way it wants. If it is a deleterious mutation, then the copy will ...

The counting of layers such as tree rings, glacial varves, and annual ice layers, is a reliable way of establishing a chronology. As far as the age of Earth is concerned, these methods provide a minimum age for Earth. Scientists do use radiometric dating to calibrate these methods from time to time—C-14 dating of some individual tree rings is an example—...

Before addressing the title of the question, I will first address the premise of the question: Creationists make the claim that a global flood has messed up the precision of radiocarbon dating and hence, it cannot be relied upon. But if it is consistently cross-referenced by other methods, then the claim doesn't quite work. If those same creationists claim ...

No, most recent studies give an equal or slightly older date for the Y Chromosome.

The book does in fact say that on page 197 (I own it). The full paragraph reads: If the potassium-argon ages of a group of rocks agree with the stratigraphic sequence determined on the basis of physical relationships of fossil evidence, then the probability is good that radiometric ages are reliable. An example of this are the data in table 7-7. For ...

This claim is wrong for so many reasons. 1) Radiometric dating relies on certain unstable elements decaying into stable ones over time. The rate of that decay is constant and can be used for measuring time - the less of the unstable element exists, the more time has passed. Nuclear explosions can create such unstable elements and throw off some dating ...
