Velociraptor
Velociraptor roamed the Earth about 85.8 million to 70.6 million years ago during the end of the Cretaceous Period.
In 1924, Henry Fairfield Osborn, then-president of the American Museum of Natural History, named Velociraptor. He bestowed the name on this dinosaur, which is derived from the Latin words "velox" (swift) and "raptor" (robber or plunderer), as an apt description of its agility and carnivorous diet.
Earlier that year, Osborn had called the dinosaur Ovoraptor djadochtari in an article in the popular press, but the creature wasn't formally described in the article and the name "Ovoraptor" wasn't mentioned in a scientific journal, making Velociraptor the accepted name.MORE
Velociraptor: Facts About the 'Speedy Thief'
Velociraptor is one of the most bird-like dinosaurs ever discovered. It was small and fast, and the sickle-shaped claw on the second toe of each foot made it a formidable predator. A special bone in its wrist allowed it to swivel its wrist sideways in a flapping motion and to fold its arm against its body like a bird. This motion allowed it to snap its arms forward to grab fleeing prey and is an important part of the flight stroke in modern birds.

There are two Velociraptor species, V. mongoliensis and V. osmolskae, the second of which was only identified in 2008.
A member of the Dromaeosauridae family of small- to medium-sized birdlike dinosaurs, Velociraptor was roughly the size of a small turkey and smaller than others in this family of dinosaurs, which included Deinonychus and Achillobator. Adult Velociraptors grew up to 6.8 feet (2 meters) long, 1.6 feet (0.5 meter) tall at the hip and weighed up to 33 lbs. (15 kilograms).
Like Tyrannosaurus rex, Velociraptor had a prominent role in the "Jurassic Park" movies, but scientists do not believe it resembled anything close to its Hollywood depiction in terms of size or appearance. In fact, the movies' Velociraptor was actually modeled after Deinonychus, and sported a similar size and snout.
While the Velociraptor was featherless in the movies, paleontologists discovered quill knobs (places where the flight-related feathers of birds are anchored to the bone) on a well-preserved Velociraptor forearm from Mongolia in 2007, indicating the dinosaur had feathers.
Despite having feathers, however, the arms of Velociraptors were too short to allow them to fly or even glide. The find suggests that the dinosaurs' dromaeosaurid ancestors could fly at one point, but lost that ability, according to the study published in the journal Science.

The American Pit Bull Terrier has been known by many names, including the Pit Bull and the American Bull Terrier. It is often confused with the American Staffordshire Terrier, however, the United Kennel Club recognizes the American Pit Bull Terrier as its own distinct breed. Affectionately known as "Pitties," the Pit Bull is known for being a loyal, protective, and athletic canine breed.The protective and fearless Pit Bull is noted for its playful temperament and friendly nature. The Pit Bull is also athletic, and has a strong desire to please people.
The Pit Bull breed has a high prey drive due to its being bred to chase and subdue livestock. However, the Pit Bull is not naturally aggressive towards people and is affectionate toward children. Depending on early socialization and handling, the Pit Bull can learn to restrain itself from unwarranted aggression towards other dogs.The Pit Bull’s origins can be traced back to early 19th-century England, Ireland and Scotland. The canine’s ancestors were the result of experimentally crossbreeding different Bulldog and Terrier breeds for the purpose of bear- and bull-baiting, a blood sport in which the dog was trained to attack until the larger animal was defeated. When baiting was banned in the 1800s, the dogs were then bred for the sport of ratting and dog fighting. European immigrants introduced the Pit Bull breed to North America.
Because of its controversial origins, the Pit Bull is not recognized by the American Kennel Club. This has resulted in the formation of two separate clubs for the specific purpose of registering Pit Bulls. The first was the United Kennel Club (UKC), which was formed in 1898 by founder C. Z. Bennett. The founder’s dog, Bennett’s Ring, was assigned UKC registration number one, making it the first registered Pit Bull in recorded history. The second club, the American Dog Breeders Association (ADBA), began in 1909 as a multiple breed association, but it has been dedicated mainly to Pit Bulls, as the original president, Guy McCord, was an avid fancier and breeder of the American Pit Bull Terrier.
Contrary to its dubious reputation as an aggressive breed, the Pit Bull is regarded by many as a friendly dog with an outgoing disposition. As those who are loyal to this breed are becoming more active in the education and training of the breed, the Pit Bull is fast becoming a popular companion pet once again.
