According to what evidence we have collected from the fossil record, dinosaurs ruled the land over what is now the Sahara desert more than 100 million years ago. But recent investigations have also revealed some of their companions, including an entire ensemble of crocodiles that seems to have accompanied the giant l... |

Dinosaurs dominated the Earth, totally or partially, for at least 160 million years before the K-T (Cretaceous–Tertiary) extinction event, which saw the disappearance of the giant lizards. The earliest of these animals were small, two-legged creatures, but some of their predecessors grew to enormous sizes, and ... |

Experts at the Southern Methodist University (SMU), in Dallas, have recently managed to electronically preserve a 110-million-year-old dinosaur footprint that was removed from its original location decades ago. The original tracks were excavated from their site, and taken to Texas, where they were built into a bandst... |

Over the course of the planet's history, there have been five extinction events that scientists know of, and each and every single one of them may have been caused by nothing more than algae. The new idea was proposed by a scientist on October 19, at the annual Geological Society of America meeting. As expected,... |

While digging at a site on the UK coasts, experts recently came across the bones of a pliosaur. While some may consider it just another dinosaur, for experts, it is one of the most important and amazing finds of the last few years. The aquatic animal was a monster, they say, one that would have made Tyrannosaurus Rex... |

Establishing what killed the dinosaurs is not an easy thing to do, and many ideas and proposals exist to explain why, some 65 million years ago, more than half of the planet's species, dinosaurs included, vanished from the face of it. A large portion of the scientific community believes that a comet impact, at t... |

Researchers in China and the United Kingdom have identified the first convincing set of pieces of evidence hinting at an unusual and controversial type of evolution, when they have discovered the remains of a peculiar flying lizard.

An international team of scientists, consisting of members from the University of Michigan, in the US, the Universidad de Buenos Aires, in Argentina, and the Iziko South African Museum, in Cape Town, South Africa, has recently revealed new clues of how dinosaurs moved down slopes.

Despite being virtually everywhere, butterflies are some of the least understood creatures on the face of the planet, as far as their evolution goes. They come in a huge variety of shapes, sizes and species, and completely lack fossil evidence on which scientists could build theories. Thanks to a new study, experts n... |

Researchers have recently discovered a new type of Tyrannosaur, one that was much smaller and graceful than its fearsome cousin Rex, while still being a vicious predator. The lizard sported some unusual features for a dinosaur, including a very long snout and a horn on its head. The find shed some light on T. Rex�... |

In a groundbreaking discovery that could potentially unlock the mystery surrounding the disappearance of dinosaurs, experts in India have uncovered an ancient dinosaur spawning ground, featuring hundreds of clusters of eggs.

In 1990, the Cheyenne River Indian Reservation, in South Dakota, provided the world with the most complete Tyrannosaurus Rex fossil to date, a beautiful specimen named Sue. The remains went on to be sold for the highest sum ever paid for a dinosaur, and became a permanent exhibit at the Field Museum of Natural Histor... |

Accord to leading paleontologists, a new, exceptionally preserved dinosaur fossil discovered in north-eastern China represents the earliest known feathered animal at this point. Estimated to have lived about 150 million years ago, the animal was petrified in mint condition, thus providing experts with the ability to ... |

While dinosaurs as Tyrannosaurus Rex are often considered to have been among the most brutal giant lizards to have ever walked the land, investigations have revealed over the years that some herbivores were not that bad at surviving, or at tearing their opponents to pieces themselves.

Paleontologists have recently managed to uncover a first-of-its-kind prehistoric "runway" for pterosaurs, the ancient, bird-like animals. The tracks, found at a location dubbed Pterosaur Beach, in southwestern France, are the first evidence to show how these animals landed, which is something that is apparently very ... |

Tyrannosaurus Rex fossils are not exactly easy to come by, and nearly complete skeletons are even more uncommon. Only a few of these exist, but most of them miss a large number of bones. That is precisely why the collector community has saluted a recent decision, to put one of the largest and most complete T. Rex ske... |

More than two years ago, a team of researchers dropped a bomb-news on the international scientific community – they had found intact proteins from a Tyrannosaurus Rex, one of the largest carnivorous dinosaurs that ever lived. Critics naturally started jumping up and down, arguing that it was essentially impossi... |

In an age when dinosaurs were still unheard of, animals living at the middle of the food chain had to adapt to being hunted down and killed by just about everyone else. And seeing how the largest and vicious predators owned the land, these animals turned to trees. The plants offered a rich source of food, and also pr... |

Despite recent controversies on the actual sizes of dinosaurs, the fact that they were the largest animals to ever inhabit the Earth remains undisputed. Anthropologists and biologists have attempted to discover the reason why they grew so big for a long time, and also what factors favored such a large size, which was... |

Life on Earth did not experience a “booming” start, with countless species appearing at once, but rather gradually, with nature trying and failing several times over before finally coming up with viable organisms. Such was the case with the first creatures who got out of the seas, and attempted to walk on... |

Never underestimate the power of sediments, anthropologists always say, as they can save valuable details over millions of years. And few are the circumstances in which they were more right.

Anthropologists and biologists have long hypothesized that birds are the modern descendants of dinosaurs, which evolved and developed flight capabilities as an adaptation to their surrounding, or as a form of defense. However, a major gap in the theory was, until now, the fact that archaeological digs failed to uncov... |

According to the results of two years' worth of excellent archeology, experts can now argue that a newly discovered “pocket of life” in Northwestern Alberta, Canada, is a missing link between species that lived further to the North, and others that lived elsewhere in what is now the country.

A newly discovered dinosaur fossil seems to change a paradigm that has been in effect for several decades, and namely that only the saurischian dinosaur families had feathers or other feather-like formations on their bodies. The heterodontosaurs that was found in China was herbivorous, and was part of a completely di... |

The remote Arctic archipelago of Svalbard has been home to one of the most disturbing archaeological finds in years, and namely that of a super-sized marine hunter, dubbed Predator X.

In the desert between the Arizona and Utah borders, scientists have discovered a huge concentration of dinosaur tracks, with more than 1,000 footprints, embedded in a single rock that is unlike those around it, in that it's not made up of sandstone.

More complex studies of all five mass extinctions that paleontologists know about have shown that, with the exception of, maybe, the last one, four global extinction events (GEE) have no plausible scientific explanation.

Latest paleontology studies showed that, in all likelihood, dinosaurs from the sauropod class were incapable of chewing their food before swallowing it, as evidenced by their long neck, which would have been too frail to sustain the massive weight of a head full of teeth. In fact, the skull was the lightest part of t... |

Newly discovered bone fragments sprung intense debates among paleontologists, who now believe that the common turtle evolved to its current state over 200 million years of evolution, from some form of lizard that looked pretty much like an armadillo.

A new study found out that early dinosaurs were far from being able to pose a threat for their competition; however, evolution in the planetary climate changed all that.
