Deep-water circulation apparently influenced the surface temperatures of the Atlantic Ocean by a great margin during the late Cretaceous Period, a team of investigators from the University of Missouri found. The discovery could be used to determine the effects of global warming on the planet.
Understanding how elev... |

Researchers at the American Museum of Natural History (AMNH), in New York City, led by Ross MacPhee, recently returned home from Antarctica with a cache of over 200 fossils belonging to marine reptiles, fish, birds, plants, and maybe even dinosaurs, possibly the largest such collection ever. The team has been trave... |

While land-based dinosaurs were competing for dominance on the surface of the Earth, an equally-powerful war was being fought in the planet's oceans, where numerous voracious species lived. In time, the mosasaurs became the ultimate predators, and scientists now analyze their rise in careful detail.According to ... |

Just recently, an international collaboration of scientists and archaeologists conducted a new expedition in Ethiopia, during which they discovered a wide array of prehistoric lifeforms, all of them trapped in amber. The 20 members of the expedition discovered 30 different arthropods solidified in the deposits, all o... |

Some 65 million years ago, a large meteorite or asteroid is thought to have hit our planet, causing one of the five large-scale, global extinction events that experts know of. The Cretaceous-Tertiary (K-T) dying saw the destruction of dinosaurs and other land- and ocean-based animals, but also the whipping off of rou... |

Paleontologists have recently made an important discovery in the state of Myanmar, when they have come acorss the fossilized remains of a “unicorn fly.” The insect was, apparently, extremely well endowed for steering clear of predators.

New archaeological data that have emerged following digs in New Mexico and Colorado seem to infirm the hypothesis that states that the catastrophic chain of events that triggered the Cretaceous-Tertiary (K-T) extinct event killed off all dinosaur species on Earth, alongside some 70 percent of all other animals and fo... |

The recently uncovered 87-million-year-old specimen of praying mantis is believed to be the "missing link" between the giant Cretaceous mantises and today's similar insects. While this is acknowledged to be truly a rare find, the importance of this discovery is yet to be evaluated. The fossil insect is 1.4... |

Turtles are grandmas amongst present-day reptiles. And it's not only about their slower movements. They appeared 250 Ma ago, before snakes, crocodiles and dinosaurs emerged. But even the oldest known turtles already had a well developed shell. Modern turtles differ a lot from those early ancestors, but many rush... |

Following the Paleozoic, when life started to get complex, the Mezozoic ("middle life", Secondary era) spanning from 250 to 65 Ma, was an era when reptiles were the rulers of the world. In fact, the dinosaurs were the real masters for over 150 million years. 1. Triassic (250-200 Ma) is named so because there are thre... |

72 millions year ago, the Mexican beaches were not roamed by tourists and mariachi, but by dinosaurs. One of them has been described in the "Journal of Vertebrate Paleontology": a large duck-billed veggie dinosaur with a sail-shaped crest.

Dinosaurs enjoyed their odor, as these ancient flowers exist since the Cretaceous Epoch (145.5 to 65.5 million years ago). They existed also in Europe till the arrival of the glaciations. But today, they are restricted to subtropical climes. About 60 % of magnolia species are found in Asia, with over 40 % growing in ... |

In our minds, the word "dinosaur" is synonymous to huge. But not all the dinosaurs were enormous beasts. And perhaps the most interesting dinosaurs were found amongst the tiny ones. Dromaeosaurs were mainly small, agile, gracile bipedal carnivorous dinosaurs that inhabited Asia and the Americas during the Cretaceous ... |
