The river rises in three separate forks in the Sierra Nevada which unite as arms of the Lake Oroville reservoir in the foothills 5 mi (8 km) northeast of Oroville in eastern Butte County. The combined stream flows generally south across the Sacramento Valley, east of the Sutter Buttes, past Oroville and Yuba City-Marysville and joining the Sacramento River from the north approximately 20 mi (30 km) NNW of Sacramento. It receives the Yuba River from the east at Yuba City and the Bear River from the east 15 mi (25 km) south of Yuba City. ...

Definition and meaning of feather star:

feather star - feather stars are echinoderms in the class Crinoidea. The juveniles attach to the substrate by a stalk with rootlike branches. The mouth side faces upward. In the adult stage they break away from the stalk and move about freely.They possess appendages, known as cirri, attached to the underside of the body with which they cling to to sponges or corals. Some can swim by undulating movements of the arms. Some have five arms, others up to 200

A number of non-avian dinosaurs are now known to have been feathered. Direct evidence of feathers exists for the following genera: Sinosauropteryx, Dilong paradoxus, Shuvuuia, Yixianosaurus, Beipiaosaurus, Caudipteryx, Protarchaeopteryx, Pedopenna, Microraptor (Cryptovolans), Sinornithosaurus, Jinfengopteryx, Epidendrosaurus (Scansoriopteryx). At present, the most primitive (known) feathered dinosaur is Sinosauropteryx (Jurassic/Cretaceous, 150-120 mya), whose body was covered with feather-like structures that look like hollow ...

After a century of hypotheses without hard evidence, beautifully preserved - and legitimate - fossils of feathered dinosaurs were discovered during the 1990s and 2000s. The fossils were preserved in a Lagerstätte — a sedimentary deposit exhibiting remarkable richness and completeness in its fossils — in Liaoning, China. The area had repeatedly been smothered in volcanic ash produced by eruptions in Inner Mongolia 124 million years ago, during the early Cretaceous. The fine-grained ash preserved the living organisms that it buried in ext ...

Shortly after the 1859 publication of Charles Darwin's The Origin of Species, British biologist and evolution-defender Thomas Henry Huxley proposed that birds were descendants of dinosaurs. He cited skeletal similarities, particularly between some saurischian dinosaurs, fossils of what was considered the "first bird," Archaeopteryx, and modern birds. In 1868 he published "On the Animals which are Most Nearly Intermediate between Birds and Reptiles," making the case; but the leading dinosaur expert of the time, Richard Owen, disagreed, claiming Archaeop ...

The impression of proto-feathers was found in the rock surrounding Sinornithosaurus. They were composed of filaments, and showed two features that indicate they are early feathers. First, several filaments were joined together into "tufts", similar to the way down is structured. Second, a row of filaments (barbs) were joined together to a main shaft (rachis), making them similar in strucure to normal bird feathers. However, they do not have the secondary branching and tiny little hooks (barbules) that modern feathers have, which ...

Over a hundred distinct anatomical features are shared by birds and theropod dinosaurs. A recent case in point: "Archaeopteryx, therefore, is closely related to the theropods. This in turn means that theropod dinosaurs are the ancestors of the modern birds that followed Archaeopteryx. The find, according to Mayr, 'not only provides further evidence for the theropod ancestry of birds, but it blurs the distinction between basal [the earliest] birds and basal deinonychosaurs,' their fearsome-clawed ancestors. 'I do think that the question of a ...

In 2004, aircraft designer Burt Rutan demonstrated the feasibility of an alternative or complementary approach to atmospheric reentry with the suborbital SpaceShipOne. SpaceShipOne has what has been described as a pair of flipping wings; the spacecraft itself changes shape for reentry. This increases drag, as the craft is now less streamlined. This results in more atmospheric gas particles hitting the spacecraft at higher altitudes than otherwise. The aircraft thus slows down more in higher atmospheric layers (which is the very ...

The styling was a fairly radical facelift by designer Brooks Stevens of the older Hawk shape; Stevens went after a European-inspired, clean look for the car he codenamed the "Hawk Monaco" (his prototype even had Monegasque license plates!). Despite the European influence, the Gran Turismo Hawk drew on American influences, too; the roofline was heavily inspired by the Ford Thunderbird, with thick C-pillars. A chrome edge running from front to rear highlighted the top of the bodywork ...

Archaeopteryx was similar in size and shape to a magpie, with short, broad wings and a long tail. The feathers resemble those of living birds, but Archaeopteryx was rather different from any bird we know of today: it had jaws lined with sharp teeth, three fingers ending in curving claws, and a long bony tail. Archaeopteryx is a powerful piece of evidence that birds evolved from dinosaurs. The skeleton is most similar to the dinosaurs of the families Dromaeosauridae and Troodontidae. Although it is probably close t ...

The dromaeosaurids are a group of agile, meat-eating dinosaurs with large claws and big brains, which include the Deinonychus and the Utahraptor. As a group, they have been poorly represented in the fossil record, and are known only from scattered bones and partial skeletons. Sinornithosaurus lived about 125 million years ago in the Barremian age of the Lower Cretaceous period, which makes it the earliest and probably the most primitive dromaeosaurid yet discovered. Sinornithosaurus is the fifth known feath ...

Velociraptor had a stiffened tail, which was always held straight behind the body. This granted it superior balance and turning ability. Like its larger American relative Deinonychus, Velociraptor may have hunted in packs to make up for its prey's size advantage, though there is no evidence for this. Velociraptor was probably warm-blooded to some degree, as it would need great quantities of energy to hunt, and animals that possess feathery or furry coats, like Velociraptor, tend to be warm ...

Velociraptor had strong jaws with rows of bladed teeth. These, in combination with large claws on their forelimbs and sickle-shaped talons on the second toe gave these animals some impressive weaponry. In 2005, a BBC documentary, The Truth About Killer Dinosaurs, created an artificial Velociraptor leg and sickle claw to demonstrate the claw's power - when tested on a pork belly, the claw failed to fully penetrate it, lending discredit to the popular notion of Velociraptor using the claw to disembowel its pr ...

There are two chief methods of sexing chicks: feather sexing and vent sexing. Chicken sexer - Feather sexing. Feather sexing is easy, but it requires that the chickens be specially bred to manifest their sex in differences in the feathers as hatchlings. Male chickens in these breeds have longer wing pinfeathers than the females do, which makes them relatively easy to tell apart. Most chickens do not have these traits bred into them, and the hatchlings are identical to all but the skilled eye of the professional chicken sexer. ...
