Pteranodon was a large pterosaur from the Upper Cretaceous period. About 1200 partial skeletons have been found, more than any other pterosaur. It lived in the area of the Western Interior Seaway.
Fossil "Pteranodon" have been found in Kansas, Alabama, Nebraska, Wyoming, and South Dakota.
With its wings open it was up to 6.25 meters across. "Pteranodon" might have lived much like an albatross, spending a lot of time over the ocean, looking for fish. It had no teeth in its long mouth, and it had a small pouch like a pelican at the back of its jaw. "Pteranodon" had a big crest at the back of its head. "Pteranodon longiceps" had a straight crest that went backwards, and "Pteranodon sternbergi" had a bigger, flatter crest that went upward.
"Pteranodon" lived mainly on offshore rookeries. Most "Pteranodon" fossils are found where, at the time, they were hundreds of kilometres from the coastline.
They certainly fed on fish. Fossilized fish bones have been found in the stomach area of one "Pteranodon". Other specimens have fragments of fish scales and vertebrae near the torso.
Females of both species were smaller than the males, and had small, rounded crests. The crests were probably used in display, though they may have had other functions as well.
Richard II of England
Richard II (6 January 1367–14 February 1400) was the son of Edward, the Black Prince, Prince of Wales, and Joan of Kent, "The Fair Maid of Kent". He was born in Bordeaux, and became his father's successor when his elder brother died in infancy. His father died before him, so he became king in 1377. His uncle John of Gaunt, the Duke of Lancaster became regent until Richard II could rule. He was deposed by Henry of Bolingbroke (Henry IV), John of Gaunt's son with Blanche of Lancaster, taken prisoner and later died in captivity.
Richard abdicated (resigned) in 1399. He was murdered later that year.
Drinker
Drinker was a small dinosaur from North America. It was a very small herbivore that grew up to 1 meter long. It was named after Edward Drinker Cope a paleontologist, a dinosaur scientist who found many dinosaur fossils such as "Triceratops", "Anatotitan" and "Tyrannosaurus rex".
Franz Ferdinand (band)
Franz Ferdinand is an indie rock band from Glasgow, Scotland. The group is named after Archduke Franz Ferdinand of Austria. Franz Ferdinand has released three albums, "Franz Ferdinand", "You Could Have It So Much Better With Franz Ferdinand", and their most recent release, "Tonight: Franz Ferdinand".
The band members are Alex Kapranos, Robert Hardy, Nicholas McCarthy, Paul Thomson.
Kress Stores
S. H. Kress & Co. was a group of "five and dime" department stores in the United States between 1896 to 1981. The business was started in Nanticoke, Pennsylvania, by Samuel H. Kress in 1896. Kress Stores were common in many cities and towns of the United States. In 1964, S. H. Kress & Co. was bought by Genesco, Inc. Genesco began closing down the stores in 1980.
The Kress chain was known for the architecture of the stores. A number of former Kress stores, now used for other things, are said to be landmarks. Some of the most well-known Kress locations included New York City's Fifth Avenue, Canal Street, New Orleans, and one at Hollywood's Hollywood Boulevard. The one at Hollywood Boulevard is now preserved at a theme park in Florida.
Henry V of England
Henry V (16 September 1386 – 31 August 1422), was the King of England from 1413 to 1422. He was born at Monmouth, Wales. It is not known whether he was born on 9 August 1386 or 16 September 1387.
Henry V was the son of Henry Bolingbroke, later Henry IV, and Mary de Bohun, who died before Bolingbroke became king.
During his reign, Henry increased his power as King of England and also took the title of King of France, over which English kings had been fighting for decades. He defeated the French at the famous Battle of Agincourt in 1415. Shakespeare wrote a play about that and made him important in other plays.
Athlete's foot
Athlete's foot is a condition where the foot is dry and cracked, which can be mildly painful. It was named athlete's foot because it was common in people who play sports or do exercise. The infection can be spread to other areas of the body, such as the armpits, knees and elbows.
Athlete's foot causes scaling, flaking, itching, blisters and cracked skin. It can be cured by using antibiotics.
Back
The word back has several meanings.
Reflection
Reflection is the change in direction of a wave at a boundary between two different media, so that the wave moves back into the medium it came from.
The most common examples include the reflection of light, sound and water waves.
Specular reflection is a mirror-like reflection of light from a surface, in which light from a single incoming direction is reflected into a single outgoing direction. In the diagram to the right, a light ray is coming from the point P, and meets at the mirror at point O. The ray reflects at the point O outwards in the same medium towards point Q. Reflection is measured relative to a line through point O that is at 90˚ to the mirror. The angles made by the light ray (shown in the diagram as formula_1 and formula_2) must be equal. Both angles have to be equal whenever reflection occurs. This is known as the "law of reflection".
People make many things to use reflections, including reflecting telescopes, radar, sonar, and lidar and putting light reflectors on things they want to see.
Caspian Sea
The Caspian Sea is the largest lake on Earth by both area and volume. It has a surface area of . Its volume is . The Caspian has for 40 to 44% of the total lake waters of the world.
The Caspian sea is an endorheic body of water. It is bordered by Russia, Azerbaijan, Iran, Turkmenistan and Kazakhstan. It has a maximum depth of about . It is called a sea because when the Romans first arrived there, they tasted the water and found it to be salty. It has a salinity of approximately 1.2%, about a third the salinity of sea water.
Complementary angles
Complementary angles are two angles that when their measurements are added together is equal to 90 degrees.
Civil rights
Civil rights are rights that all people in a country have. The civil rights of a country apply to all the citizens within its borders. These rights are given by the laws of the country. Civil rights are sometimes thought to be the same as natural rights.
In many countries civil rights include freedom of speech, freedom of the press, freedom of religion, and freedom of assembly. Civil rights also include the right to own property and the right to get fair and equal treatment from the government, from other citizens, and from private groups. They may prevent against discrimination based on race, sexual orientation, gender, gender identity and disability.
Civil rights are protected by law and custom. The constitutions of many democracies have a "Bill of Rights" that describes the people's liberties and rights. A well-known example is the United States Bill of Rights.
A court of law decides if a person's civil rights have been violated. The courts also decide the limits of civil rights, so that people do not use their freedoms to take away the rights of other people.
Moscovium
Moscovium is a chemical element. It is also named eka-bismuth. It has the symbol Mc. It has the atomic number 115. It is a superheavy element. Moscovium does not exist in nature. It is a synthetic element, made from a fusion reaction between americium and calcium.
The element is named in honor of the Russian city of Moscow.
Moscovium is in or near the center of the theoretical island of stability. No stable isotopes of moscovium have yet been found. Models predict that the stable isotope of ununpentium should have 184 neutrons. The most stable isotope with 184 neutrons is Mc. The isotope that has been made has only 175 neutrons (Mc).
