1. Dinosaur

   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.

1. dinosaur

   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.

Examples of Dinosaur in a Sentence

1. Darla Zelenitsky:

   If we look at the eggshells with a microscope, we can see the tiny structures that make up the eggshell, these eggshell structures reveal the type of dinosaur or animal that laid the eggs.

2. David Greenwood:

   The discovery of charcoal together with a fern-filled stomach opens a window into the biology of this large herbivorous armoured dinosaur as it suggested Borealopelta was likely a keystone herbivore that shaped the landscape by its grazing, and that it also grazed on the ferns growing in open areas created by wildfires, that is so cool.

3. Thomas Carr:

   We're learning about the rules of dinosaur evolution, it shows that the dinosaurs across theropods and sauropodomorphs and even ornithischians tend to follow the same rules in changing their bodies.

4. Susannah Maidment:

   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.

5. Cindy Howells:

   This dinosaur was very small, it was an agile, meat eating creature with sharp teeth, sharp claws, able to move swiftly and grab its prey. We don't quite know what it would have eaten, but possibly small reptiles, small mammals, and possibly other dinosaurs as well. It was a bit like a medium sized dog, very slender, very long-tailed to help it balance as it moved.
