Extinct Giant Whale-Eating Whale Found

Extinct Giant Whale-Eating Whale Found
- Unlike modern sperm whales, this one had teeth in both jaws and might have eaten like killer whales. - The 10-foot sperm whale skull fossil is the largest ever found. - Its main food might have been baleen whales. The massive skull and jaw of a 13-million-year-old sperm whale has been discovered eroding from the windblown sands of a coastal desert of Peru. The extinct cousin of the modern sperm whale is the first fossil to rival modern sperm whales in size -- although this is a very different beast, say whale evolution experts. "We could see it from very far," said paleontologist Olivier Lambert of the Muséum National d'Histoire Naturelle in Paris, France, who led the team which found the fossil.

Fossils Reveal Oldest Known Vertebrate Live Birth A 248 million-year-old fossil Ichthyosaur shows a stunningly preserved female with three embryos inside. This pushes the timeline for vertebrate live births back 10 million years. The discovery comes a team led by Ryosuke Motani of UC Davis and was published in PLOS One. The development of offspring inside the mother is known as viviparity, which is used by most mammals along with certain examples of arthropods, sharks, and snakes. This method is opposed to oviparity, which is when a mother does not facilitate development aside from laying eggs, which is seen in birds and most reptiles, insects, and fish.

Glyptodon Evolution[edit] Restoration Glyptodon carapace fragment (Pleistocene). Glyptodon is part of the superorder of placental mammals known as Xenarthra. This clade of mammals also includes anteaters, tree sloths, armadillos, and extinct ground sloths and pampatheres. Einstein’s God: Krista Tippett and Theoretical Cosmologist Janna Levin on Free Will, Science, and the Human Spirit by Maria Popova “How we ask our questions affects the answers we arrive at… Science and religion… ask different kinds of questions altogether, probing and illuminating in ways neither could alone.” Seven decades after a little girl asked Einstein whether scientists pray, Peabody Award-winning journalist Krista Tippett began interviewing some of the world’s most remarkable scientists, philosophers, and theologians about the relationship between science and spirituality in her superb public radio program On Being — the same trove of wisdom that gave us Sherwin Nuland on what everybody needs and Joanna Macy on how Rilke can help us live more fully.

11 Extinct Animals That Have Been Photographed Alive Animals Published on April 2nd, 2009 | by Bryan Nelson The current rate of extinction is 100 to 1000 times higher than the average, or background rate, making our current period the 6th major mass extinction in the planet’s history. Although fossil reconstructions or pictorial representations can sometimes be difficult to connect with, it’s impossible to ignore the experience of seeing a photograph of an animal on the brink of extinction. Thus, what follows is a list of 11 extinct animals that were photographed while still alive. A Lower Cretaceous ichthyosaur graveyard in deep marine slope channel deposits at Torres del Paine National Park, southern Chile + Author Affiliations Remnants of ophthalmosaurid ichthyosaurs recently discovered in the vicinity of the Tyndall Glacier in the Torres del Paine National Park of southern Chile are extremely abundant and well preserved. After three field campaigns to the area, a total of 46 articulated and virtually complete ichthyosaur specimens, both adults and juveniles, were tentatively assigned to four different species of Ophthalmosauridae. Preservation is excellent and occasionally includes soft tissue and embryos.

Scientists Discover Blood inside 15,000 ya Mammoth Russian scientists claimed Wednesday they have discovered blood in the carcass of a woolly mammoth, adding that the rare find could boost their chances of cloning the prehistoric animal. An expedition led by Russian scientists earlier this month uncovered the well-preserved carcass of a female mammoth on a remote island in the Arctic Ocean. Semyon Grigoryev, the head of the expedition, said the animal died at the age of around 60 some 10,000 to 15,000 years ago, and that it was the first time that an old female had been found. But what was more surprising was that the carcass was so well preserved that it still had blood and muscle tissue. "When we broke the ice beneath her stomach, the blood flowed out from there, it was very dark," Grigoryev, who is a scientist at the Yakutsk-based Northeastern Federal University, told AFP.

“One Last Time” Star Ariana Grande Doppelganger becomes an Instagram hit Although Grande Ariana is certainly unique for their fans, which is “one last time” hit maker often copied. Especially her look did it the girls all over the world. However, none is so perfect double as the Irish Jacky Vasquez. With songs such as “one last time” climbs Ariana Grande (21) regularly the chart tips. The success made them known internationally. Clear that the fans want to emulate her idol, and accordingly to style.

10 Most Amazing Extinct Animals From the Quagga --half zebra, half horse-- to the Irish Deer --the largest deer that ever lived--, an impressive list with pictures of amazing animals we will never see. Tyrannosaurus Rex (extinct 65 million years ago) [Wiki] Tyrannosaurus rex was one of the largest land carnivores of all time, measuring up to 43.3 feet long, and 16.6 ft tall, with an estimated mass that goes up to 7 tons. Like other tyrannosaurids, Tyrannosaurus was a bipedal carnivore with a massive skull balanced by a long, heavy tail. Relative to the large and powerful hindlimbs, Tyrannosaurus forelimbs were small and they retained only two digits.

Ammonoidea Ammonites are excellent index fossils, and it is often possible to link the rock layer in which a particular species or genus is found to specific geological time periods. Their fossil shells usually take the form of planispirals, although there were some helically spiraled and nonspiraled forms (known as heteromorphs). Diagnostic characters[edit] Ammonites (subclass Ammonoidea) can be distinguished by their septa, the dividing walls that separate the chambers in the phragmocone, by the nature of their sutures where the septa joint the outer shell wall, and in general by their siphuncles.

10 Transitional Ancestors of Human Evolution Humans The evolution from our closest non-human ancestor to present day humans is one with many transitions. Some of these transitions are widely agreed upon by the scientific community while others are shrouded in frustrating darkness. Below are the ten species that have added the most to our lineage, some adding seemingly simple advances like walking on two legs and chewing food differently to mastering fire and dominating every other species on Earth.
