Dinosaur Extinction Theory #481b
April 22, 2004
Let’s try another one.  Temperature imbalances after the asteroid impact 65 million years ago caused cooler global temperatures.  This caused more eggs to hatch male, since in reptiles, egg temperatures can influence the sex of the hatchlings.  So a shortage of females gradually led to the extinction of the dinosaurs.     Why, then, didn’t […]

Antarctic Dinosaurs Found

Rex and velociraptor are examples), was perplexed by the find: […]

How Snakes Lost Their Limbs
February 2, 2004
Penn State scientists have a story for how snakes, which presumably evolved from lizards, lost their legs.  They had to burrow through tight places.     Part of their story involved disproving that snakes evolved from sea-going reptiles, like mosasaurs, explains the press release from Penn State’s Eberly College of Science.  They compared genes from […]

How Darwinism Produces Job Security
December 22, 2003
One thing Darwinism has going for it: it provides endless opportunities to research stories that are nearly impossible to prove.     A case in point was provided in the Dec. 18 issue of Nature.1  John R. Hutchinson (Royal Veterinary College, UK), in a News and Views article on bird evolution, reviewed the new angle […]

If a Meteor Roasted the Dinosaurs, Where’s the Charcoal?
December 4, 2003
A majority of scientists continue to believe that a falling asteroid felled the dinosaurs 65 million years ago, but problems remain.  London geologists went looking for evidence of charcoal at the Cretaceous-Tertiary layers, when the assumed impact occurred, assuming that the force of impact would have ignited a worldwide conflagration (thus the extinction of the […]

Farewell, Cannibal Dino
September 20, 2002
Whoops, We Were Wrong Dept.:  Fossils of Coelophysis found in 1947 included members of the same species in the stomach, so they were cannibals, right?  Not so fast, corrects an article in BBC News.  The food now looks more like filet of crocodile.  After re-examining the evidence, researchers from Columbia University and the American Museum […]

Waltzing with Dinosaurs
September 20, 2002
51; An international team of paleontologists wrote a kind of “State of the Tyrannosaur Address” in Science last week,1 boasting about all that is known of these creatures: Tyrannosaurs, the group of dinosaurian carnivores that includes Tyrannosaurus rex and its closest relatives, are icons of prehistory.  They are also the most intensively studied extinct dinosaurs, […]

Ichthyosaurs Suddenly Appeared in Triassic Oceans
April 20, 2002
“Ichthyosaurs were a group of Mesozoic marine reptiles that evolved fish-shaped body outlines,” begins Ryosuke Motani (UC Davis) in the Annual Review of Earth and Planetary Sciences,1 in a paper on “Evolution of Fish-Shaped Reptiles… in Their Physical Environments and Constraints.”  But while much is said about their environments and constraints, little is said to […]

Daffy Duck Found in Dino Park
