Anthropologists and paleontologists have known for a long time that the desolate stretches of inhospitable sand that make up the Sahara desert hide a large number of amazing artifacts, dating from as far back as the age of the dinosaurs. While other excavation sites revealed the ancient history of Egypt, a particular... |

Recent anthropological studies revealed that the head of large dinosaurs, such as Tyrannosaurus Rex, was more filled with sinuses than with brains, which seems to have prompted their remarkable ability of catching the prey, despite their bulky mass and constitution. CT scans of their heads revealed that the amount of... |

There are probably a lot of people who don’t know about Michael Crichton's work (or if what they watched or read was actually his creation), but, certainly, those who have heard about him are indeed saddened by the recent passing of the beloved Sci-Fi author. "Jurassic Park" (1990) or "Sphere" (1987) are a... |

The recent discovery of the Microraptor gui species of dinosaur (translated as “Small thief” or “Small raider”) stands as further proof that dinosaurs are the ancestors of modern birds. The fact that puzzled researchers was its being provided with two sets of wings, which is highly unusua... |

In 2005, a team of paleontologists rushed to claim that they had discovered soft tissue in a dinosaur fossil belonging to a Tyrannosaurus rex that lived more than 65 million years ago. Now, a new study contests the findings of the previous one by revealing that the so-called soft tissue sample is in fact only a biofi... |

The fossilized skeleton of a dinosaur closely related to the famous giant carnivorous Tyrannosaurus, unearthed in the Gobi Desert in Mongolia in 2006 by Japanese and Mongolian scientists, is now presented by the Hayashibara Museum of Natural Sciences as one of the most complete fossils of this species ever found. The... |

In 1971, while prospecting for thorium in the northern regions of British Columbia, geologist Kenny Larsen discovered the fossils of a dinosaur. Since thorium is a radioactive element, Larsen was equipped with instruments capable of measuring the levels of radiation in the surrounding medium. Thus, he detected a radi... |

During a tour of a region where nearly eight years ago a mummified duckbill was found, a public relations coordinator from the Texas museum discovered the fossil of a duckbilled dinosaur that roamed the Earth some 75 million years ago. Leonardo, as the mummified specimen found in Montana was named, is currently on di... |

You would think that with a reputation such as that of Tyrannosaurus rex even their youngsters would be at bay from predators. A new study now says that this was hardly the case, especially in the presence of flying reptiles such as Pterosaurs, a dinosaur living between 230 and 65 million years ago. Prior to the stu... |

Similar dinosaur tracks have been found throughout the world during the years, but this is the first time when these are found in the Arabian Peninsula. The site of the discovery presents the fossilized footprints of 11 sauropods walking together roughly at the same speed along a Mesozoic coastal mudflat. Sauropods w... |

T-Rex is by far the most famous of dinosaur species. For 150 years, Tyrannosaurus rex was considered the largest carnivorous species that have ever roamed the earth. And it was, indeed, a huge beast - up to 12.8 (42 ft) in length and 7.2 tonnes in weight. Bigger than an elephant! Meanwhile, in 1993, a longer carnivor... |

The ordinary lard is more than familiar to most of us. However, mammals also have a different fatty tissue called brown fat, involved in generating heat. A new study made at New York Medical College and published in the journal BMC Biology has discovered why birds lack this tissue. In the end, birds are actually livi... |

The species was found in Coahuil... |

One group of huge marine reptiles that dominated the seas during the dinosaur eras (Jurassic and Cretaceous, 200 to 65 Ma ago) was represented by the plesiosaurs, long-necked small-headed carnivore animals with flippers resembling those of the sea turtles. These were the animals that inspired the legend of the Loch N... |

There are mummies which can be older than those of the ancient pharaohs. Some even older than 65 Ma.

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... |

We know that some carnivorous (theropod) dinosaurs were feathered. Archaeopteryx, the oldest bird-dinosaur fossil discovered, was feathered, too. But the fossils preserved only imprints of feathers, as the feathers themselves degrade in time. However, this new discovery published in the journal "Proceedings of the R... |

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. Velafrons coahuilensis lived just 7 million years before the dinosaur demise. ... |

1.The name "dinosaur" comes from Old Greek "deinos" ("terrible") and "saurus" ("lizard"), and was advanced by Richard Owen in 1841. The dinosaurs emerged at the end of the Triassic, about 225 million years ago, from a group of reptiles called Archosauria. Archosauria was a sister group to lizards and they gave birth ... |

We are more familiarized with the ferocious meat-eating dinosaurs, like T-rex. But some appear to have been skilled fishers, too! Baryonyx was found in 1983 near Dorking in Surrey, UK. It was 125 million years old, and was classified to the family of spinosaurs. The beast was up to 10 m (33 ft) long and weighed up to... |

T-rex was not exactly the champ of the bullies during the dinosaur era. It was indeed up to 12.8 (38 ft) long and 7.2 tonnes heavy (more than an elephant!), but the 1993 discovered Giganotosaurus from Argentine was longer: up to 13.6 m (40 ft) long. Still, the largest carnivore dinosaur (and land carnivore in genera... |

If you had walked the Earth 150 to 65 million years ago, the birds would have seemed very strange to you. First, they all displayed a mouth full of fearsome teeth.
