POPSMass Extinction Event On the Horizon? Mass Extinction Event On the Horizon? Nope, were in it now. Any scientist studying some aspect of the environment will tell you that humans are having a massive impact and that the Earth's ecosystem will not tolerate this forever.

POPSDinosaur evolutionary tree unveiled It remained at that low level throughout the following Cretaceous period, a time of plenty in Earth's terrestrial history in which flowering plants, lizards, snakes, birds and mammals all became much more numerous. Dinosaurs apparently did not take advantage of the abundant food supply that emerged during the Cretaceous Terrestrial Revolution. "Our supertree allows us to look for unusual patterns across the whole of dinosaurs for the first time," says Lloyd. "It is the most comprehensive picture ever produced of how dinosaurs evolved."

POPSDinosaurs Diversified Over Time, not Suddenly During this epoch of riotous biodiversity, flowering plants, social insects, butterflies, modern groups of lizards, mammals, and possibly birds, too, all emerged. Some experts have suggested that dinosaurs were also part of the show, as so many weird fossils, such as duckbilled hadrosaurs, horned ceratopsians, pachycephalosaurs and other wonders, date from this time. But a new study, published on Wednesday in a British journal Proceedings of the Royal Society B, says that dinosaurs were less than a sideshow in the DNA spectacular. Researchers led by Graeme Lloyd of the University of Bristol, western England, devised a "supertree" of dinosaur evolution, patiently analyzing how more than 450 species -- about 70 percent of the known finds -- developed.

POPSDino diversity earlier than first thought Maybe there is the idea that species including the dinosaurs were trying to deal with conditions brought about by the meteor, so many adaptations arose, but nature loves nothing more than competition, even when times are good.

POPSA roar from the past :) Each Parasaurolophus probably had a voice that was distinctive enough not only to distinguish it from other dinosaurs, but from other Parasaurolophuses. The sound may have been somewhat birdlike, and they may have made songs of some sort to call to one another.

POPSOceans to fall, not rise over millennia Of course they're talking about a geological timespan -80 Million Years. That doesn't change the potential rise over the next 10-100 years. A mere flash in geological time. There is a curious reason, The oceans are becoming deeper. Changes caused by continental drift being the primary cause. For example The Atlantic will widen, and the Pacific will shrink. While they say the estimated drop is around 120 m, if the Ice on Greenland and Antarctica happened to melt, as it seems to be doing today, the drop would only be 70 m

POPSScientists find 'Devil toad ' fossil This guy was so 'intimidated' by the size of this little he named it 'Beelzebufo'. He has obviously never met an Australian cane toad, I started to write a bit aboit cane toads, then I thought I'd give them their own clip next

POPS105 foot Dinosaur unearthed in Argentina. Love the name Futalognkosaurus dukei Mapuche indian word for giant/chief. The Duke is an energy Co, It was big, but mainly around the middle but it also had a very long neck and tail. The skeleton was one of the most complete ever found. When I saw the Indian word for giant, I wondered why the English words big,giant, and titan seemed to be so small by comparison. Of course English is a weird language.

POPSDissidents Against Dogma "A geologist has a much longer perspective. There are several salient points about our earth that the greenhouse theorists overlook (or are not aware). The first of these is that the planet has never been this cool. There is abundant fossil evidence to support this--from plants of the monocot order (such as palm trees) in the rocks of Cretaceous Age in Greenland and warm water fossil in sedimentary rocks of the far north. this is hardly the first warming period in the earth's history. The present global warming is hardly unique. It is arriving pretty much "on schedule." One thing, for sure, is that the environmental community has always spurned any input from geologists (many of whom are employed by the petroleum industry). No environmental conference, such as Kyoto, has ever invited a geologist, a paleontologist, a paleoclimatologist. It would seem beneficial for any scientific investigatory to include such scientific disciplines.
