/article/la-brea-tar-pits
Tim Clarey, Ph.D. - The La Brea Tar Pits have fascinated visitors ever since Spanish explorer Gaspar de Portolá chronicled the site in 1769.1 But even before that, humans had likely used the “tar” for several thousand years. Using land donated to...

/article/more-mixed-land-and-marine-fossils-wales
Tim Clarey, Ph.D. - Flood geologists expect to find marine fossils mixed in the same layers as land animal and land plant fossils. We see it all over the world.1,2 Scientists can directly observe the results of massive waves, created by tectonic activity, that...

/article/salamander-like-tetrapod-didnt-live
Tim Clarey, Ph.D. - A recent discovery of a crocodile-size tetrapod (four-legged animal) in high latitudes has some conventional scientists baffled.1 How could cold-blooded animals survive in cold-temperature regions? And, according to the evolutionary story, these...

/article/t-rex-not-as-smart-as-thought
Tim Clarey, Ph.D. - Have movies and most conventional paleontologists got it all wrong? T. rex and other theropod dinosaurs (the meat-eaters) are often portrayed as intelligent predators that can outmuscle and outsmart their opponents. But is that really supported...

/article/bergmanns-rule-falsely-refuted
Tim Clarey, Ph.D. - A recent study of dinosaur sizes claims to break Bergmann’s rule.1 Bergmann’s rule was named after biologist Carl Bergmann, who in 1847 noticed that warm-blooded animals tended to be larger in cold climates compared to the same animal...

/article/hot-national-park-hydrothermal-springs
Tim Clarey, Ph.D. - Hot Springs National Park is located about an hour southwest of Little Rock in the folded Ouachita Mountains of central Arkansas. It is the second smallest national park in the United States at just under nine square miles. Park employees like to...

/article/moroccan-dinosaurs-marine-rocks
Tim Clarey, Ph.D. - Two recent papers by paleontologist Nicholas Longrich and his colleagues describe some unexpected findings in phosphate mines of northern Morocco.1,2 Most surprisingly, they found a pair of short-armed carnivorous dinosaurs mixed in with fish,...

/article/dolomite-problem-best-solved-by-flood
Tim Clarey, Ph.D. - Dolomite is a very common sedimentary rock, comprising about 30% of all carbonate rocks.1,2 Its chemical formula is MgCa(CO3)2, whereas the more common limestone is CaCO3. Oddly, ocean water is supersaturated with respect to dolomite, yet it...

/article/fossil-solves-land-marine-mixing-andes
Tim Clarey, Ph.D. - A recent article published by Hakai Magazine claims to reveal secrets of an ancient inland sea that existed east of the Andes Mountains,1 but it really just offers poor explanations for an already murky evolutionary tale and leaves the reader...

/article/rocks-major-contributor-to-atmospheric-co2
Tim Clarey, Ph.D. - Most of us have heard about the steady increase in CO2 in the earth’s atmosphere, sometimes called the Keeling Curve.1 Many have tied this current upswing to climate change, and many have blamed the burning of fossil fuels for this...
