alt. of Dinosaurian
Dinosaurs are a diverse group of animals of the clade Dinosauria. They first appeared during the Triassic period, approximately 230 million years ago, and were the dominant terrestrial vertebrates for 135 million years, from the beginning of the Jurassic until the end of the Cretaceous, when the Cretaceous–Paleogene extinction event led to the extinction of most dinosaur groups at the close of the Mesozoic Era. The fossil record indicates that birds evolved from theropod dinosaurs during the Jurassic Period and, consequently, they are considered a subgroup of dinosaurs by many paleontologists. Some birds survived the extinction event that occurred 66 million years ago, and their descendants continue the dinosaur lineage to the present day. Dinosaurs are a varied group of animals from taxonomic, morphological and ecological standpoints. Birds, at over 9,000 living species, are the most diverse group of vertebrates besides perciform fish. Using fossil evidence, paleontologists have identified over 500 distinct genera and more than 1,000 different species of non-avian dinosaurs. Dinosaurs are represented on every continent by both extant species and fossil remains. Some are herbivorous, others carnivorous. While dinosaurs were ancestrally bipedal, many extinct groups included quadrupedal species, and some were able to shift between these stances. Elaborate display structures such as horns or crests are common to all dinosaur groups, and some extinct groups developed skeletal modifications such as bony armor and spines. Evidence suggests that egg laying and nest building are additional traits shared by all dinosaurs. While modern birds are generally small due to the constraints of flight, many prehistoric dinosaurs were large-bodied—the largest sauropod dinosaurs may have achieved lengths of 58 meters and heights of 9.25 meters. Still, the idea that non-avian dinosaurs were uniformly gigantic is a misconception based on preservation bias, as large, sturdy bones are more likely to last until they are fossilized. Many dinosaurs were quite small: Xixianykus, for example, was only about 50 cm long.
Chambers 20th Century Dictionary
dī′no-sawr, n. a gigantic extinct reptile, which attained a length of eighty feet. [Formed from Gr. deinos, terrible, and sauros, lizard.]

1. Any hardware requiring raised flooring and special power. Used especially of old minis and mainframes, in contrast with newer microprocessor-based machines. In a famous quote from the 1998 Unix EXPO, Bill Joy compared the liquid-cooled mainframe in the massive IBM display with a grazing dinosaur “with a truck outside pumping its bodily fluids through it”. IBM was not amused. Compare big iron; see also mainframe. 2. [IBM] A very conservative user; a zipperhead.

This discovery overturns decades-old ideas that non-bird dinosaurs were restricted to terrestrial environments, so, yes, we believe that this discovery does indeed revolutionize our understanding of dinosaur biology.
This is the most diverse dinosaur track fauna ever recorded, if we went back in time 130 million years ago, we would've seen all these different dinosaurs walking over this coastline. It must've been quite a site.
Although we have found dense internal structures that we have interpreted as nuclei in our cells, and the cells we found appear to preserve original components of blood, there is no evidence of any organelles or DNA within the nuclei, but even if one was to find some fragments of DNA, we would not be able to reconstruct a dinosaur 'Jurassic Park-style' because we would need the complete genome to figure out where the holes in the DNA are.
We found the dinosaur's huge vertebrae with the skull and the tail, but couldn't find any bones from the hands or the legs. So the locals began to say the long body looked just like a dragon from ancient Chinese stories.
I knew that we needed something dramatic for what would inevitably be a centerpiece of the hall. And these are two dinosaur species that co-existed 68-66 million years ago in western North America, so it would represent a possible real-world interaction, but we've deliberately left the scenario open, as to whether this represents T. rex killing Triceratops or scavenging an already dead individual. The idea is to better portray the role of an apex predator, which is often opportunistic. In life, I imagine that even T. rex would have favored easier meals than a healthy, adult Triceratops – if such were available: young or sick or elderly individuals, for example.
