Though not all dinosaurs were behemoths, some grew to be more than 100 feet (30 meters) tall. Experts have always wondered what made the creatures grow so tall, and now they are starting to form a picture of the factors that interacted to make this a reality.
Some of the contributing factors may sound weird at firs... |

A massive extinction event that occurred at the end of the Triassic Period still has researchers baffled. It represents one of the most mysterious mass dyings in the history of the planet, and some believe that it was caused by an asteroid. Scientists are currently looking for a potential impact crater.
The event o... |

A team of investigators is proposing that an enormous, Kraken-like marine invertebrate may have roamed our planet's oceans between 250 and 200 million years ago. While no direct evidence of the creatures exists, they may have left behind gruesome, tell-tale signs of their presence.
Investigators made the rec... |

Experts announce the discovery of a never-before-seen species of dinosaurs that roamed in South American more than 230 million years ago, when the giant lizards were barely beginning to develop and assume dominance over all ecosystems. The finding was made by a collaboration of geologists and paleontologists based in... |

The Luoping fossil site in the Yunnan Province in south-west China, has provided valuable fossils that shed light on the way that life on Earth has recovered from the greatest mass extinction in our planet’s history.
The work is led by scientists from the Chengdu Geological Center in China and was presented ... |

The events that unfolded about 250 million years ago, at the Permian-Triassic boundary, are some of the most mysterious in history. At that moment, over a short period of time, more than 90 percent of all animals and plants on the surface of the planet died off, in a massive extinction event, for which satisfactory e... |

It's widely accepted in the scientific community that a massive extinction event took place on Earth between the Permian and the Triassic periods, wiping up almost 90 percent of both marine and land species and driving the ancestors of dinosaurs to the brink of extinction. Now, a team of researchers is seeking t... |

A researcher at the Johns Hopkins University (JHU) School of Medicine argues in a recent study, published in the journal Zitteliana, that pterosaurs, the giant 500 pound (roughly 250 kilograms)-heavy flying reptiles that lived from the late Triassic to the end of the Cretaceous Period, between 220 and 65.5 million ye... |

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. The 210 million year old fragments, found at a site in New Mexico, ... |

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. At the beginning of the Triassic period, the planet was inhabited by a group of ruling reptilians called archosaurs. Over the next 10 million y... |

The fossilized burrow found recently in Antarctica and dated to the Early Triassic epoch is thought to have belonged to tetrapods - land vertebrates with four legs or appendages resembling legs - and was created when a nearby river overflowed, filling it with fine sand that hardened later on. No remains of the animal... |

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... |
