Another argument for the warm-blooded theory has to do with looking at the anatomy of dinosaurs and at the similarities with warm-blooded animals. If you look at what’s around today, well, let’s see, today anything that walks on two legs is warm-blooded. That goes for humans and ...
"Early mammals coexisted with early reptiles in the Age of the Dinosaurs and somehow escaped extinction," Wu was quoted as saying in a news release. "This research further supports the hypothesis that diurnal reptiles, such as lizards, snakes and their relatives, competed with mammals and may h...
"Early mammals coexisted with early reptiles in the Age of the Dinosaurs and somehow escaped extinction," Wu said. "This research further supports the hypothesis that diurnal reptiles, such as lizards, snakes and their relatives, competed with mammals and may have led them to better adapt to di...
A review of 100 years of fossil evidence reveals that 100 million years ago part of the Sahara Desert was arguably the riskiest place on our planet,wih a concentration of large predatory(食肉的)dinosaurs unmatched in any comparable modern ecosystem on land. The analysis of fossils from theso-...
havstad in "The Philosophy of Macroevolution." This long-term process is what turned dinosaurs into birds, amphibious mammals (such as an animal called Indohyus) into whales and a common ancestor of apes and humans into the people, chimps and gorillas we know today. Darwin also described a...
Co-author Christopher Beard, a paleontologist at the University of Kansas in Lawrence who has been working on Shanghuang fossils for 25 years, said the limestone in the quarry is ofTriassicage—from the very beginning of the Age of Dinosaurs some 220 million years ago. Owing to a subseque...

Humans came out of Africa: live with it. 3. There were no dinosaurs 25 million years ago. 66 million ago, yes – until the large chunk of rock that resulted in their extinction barrelled in. 4. H erectus was no more a monkey than we are. Some examples notwithstanding…. Reply ...
Analysis of the data showed that the red dwarf's magnetic activity cycle lasted 600 days, which is consistent with the magnetic cycles estimated for low-mass isolated stars. The binary's orbital period was estimated at 17 years. "This completely refutes the hypothesis that orbital period variati...
“I have studied birds skulls for twenty-five years. I do not see any similarities whatsoever between them and dinosaurs. The theropod origins of birds, in my opinion, will be the greatest embarrassment of paleontology of the 20thcentury”.[23] ...
