Studies suggest that the paleoenvironment of this part of the Morrison Formation had rivers flowing from the west into a basin with a giant, saline alkaline lake. There were extensive wetlands nearby. Fossils from the Dry Mesa Dinosaur Quarry of western Colorado show one of the most diverse Upper Jurassic vertebrate assemblages in the world. The Dry Mesa Quarry has produced the remains of the sauropods "Apatosaurus", "Diplodocus", "Barosaurus", "Supersaurus", "Dystylosaurus", "Camarasaurus", the iguanodontid "Camptosaurus", and the theropods "Allosaurus", "Ceratosaurus" and "Ornitholestes", as well as "Dryosaurus", and "Stegosaurus".
Life (BBC TV series)
Life is a 2009 British biology show made by the BBC with many parts. The shows include the animals' aspect of the environment, as well as some examples of how the environment needs what it does.
An episode is divided into "parts", examples of how different animal species must adhere to the environment.
Brassica oleracea
Brassica oleracea, or wild cabbage, is a species of "Brassica" native to coastal southern and western Europe.
Its tolerance of salt and lime, and its dislike of competition from other plants, restrict it to limestone sea cliffs, like the chalk cliffs on both sides of the English Channel.
"B. oleracea" is believed to have been cultivated for several thousand years. It has been bred into a wide range of cultivars, including cabbage, broccoli, cauliflower, and more. Some of which are hardly recognisable as being members of the same genus, let alone species.
The plant is used because of its large food reserves, which are stored over the winter in its leaves. It is rich in essential nutrients including vitamin C.
The cultivars of "B. oleracea" are grouped into seven major cultivar groups, of which the Acephala Group remains most like the natural wild cabbage in appearance:
All are in the same species. However, artificial selection has brought about genetic differences between the groups.
In places such as the Channel Islands and Canary Islands where the frost is minimal, and plants can grow all year round, some cultivars can grow up to 3 meters tall. These "tree cabbages" yield fresh leaves throughout the year, and the plant is not destroyed as with a normal cabbage. Their woody stalks are sometimes dried and made into walking sticks.
Some (notably brussels sprouts and broccoli) contain high levels of sinigrin which may help prevent bowel cancer.
PlayStation Portable system software
The PlayStation Portable has firmware that can get an update. When one updates the firmware, the battery must be charged (to 3 bars, i.e. 60%), and the PSP should not be switched off. This may result in a brick and/or a constant startup BSOD or another screen "of death". As of August 10, 2011, the latest firmware is 6.60.
Sintering
Sintering is a way of making solids objects from powder.
During sintering powder is heated just before it would melt. In this way, powder particles bind to each other and form a solid object.
Covenant
A covenant is a formal agreement, a promise made between two people. It is often used as a religious promise. It can also be an item which is a symbol of keeping the promise. Some covenants include stone tablets, written documents, and other sacred items. In Judaism, the Ark of the Covenant was a wooden box which held the stone tablets with the Ten Commandments written on them. The Jewish people saw the box as a symbol of God being with them and leading them.
Least concern
Least concern is a term used by the International Union for the Conservation of Nature (IUCN) to talk about living things that are not endangered. They do not need to be worried about because there are many of them found at the time of classification.
Here is a list of mammals that are least concern. They include:

French Communist Party
The French Communist Party (, PCF) is a French far left-wing political party. Founded in 1920, it had a large influence in the XXth century, especially after the Second World War, and is still important in the French political life, though it declined over years.
Its National Secretary is Pierre Laurent, since June 2010.
The French Communist Party was founded in 1920 after the Tours Congress of the French Section of the Worker's International (SFIO, today the Socialist Party), as the French Section of the Communist international (SFIC), by members who wanted to join the Third International. It took in 1921 the name of "Communist Party".
In 1936, it was a part of the Popular Front and supported its social reforms, but refused to participate in the government.
During the Second World War, the PCF became a clandestine organisation and organised a massive armed resistance against the Nazi occupation. At the Liberation, the party was the most important in France and had several ministers in the Provisional Government. However, its support to independentist movement in French Indochina and to strikes isolated it from other parties.
From the 1930s to the 1980s, the French Communist Party's line is close to the Soviet Union's. The collapse of the USSR in 1991 also affects the PCF, whose electoral support decreases rapidly.
At the French 2007 legislative election, the PCF gained 4.29% of the votes, one of its worst results. However, the Communist party is still one of the most important party in some regions of France (Seine-Saint-Denis, Nord...), where it has been historically strong.
In 2009, the PCF created the "Left Front" () with the Left Party, and ran as a part of this alliance in the 2009 European Parliament election and the 2009 Regional election, with some success.
Marcus Aurelius
Marcus Aurelius Antoninus (26 April 121 – 17 March 180) was Roman Emperor from 161 to 180. He ruled with Lucius Verus as co-emperor from 161 until Verus' death in 169.
He was the last of the Five Good Emperors, and is considered one of the most important Stoic philosophers.
Marcus Aurelius' work "Meditations", written in Greek while on campaign between 170 and 180, is still revered. It serves as an example of how Aurelius approached the Platonic ideal of a philosopher–king, and how he symbolized much of what was best about Roman civilization.
At the start of his reign, the Empire, under the joint rule of Marcus and Lucius Verus, defeated a revitalized Parthian Empire in a war from 161 to 166.
The unforeseen consequences for the Empire were great. The returning troops brought with them a plague (the so-called Antonine Plague), which may have been smallpox. It would eventually kill about 5 million people, and severely weaken the Empire.
Aurelius fought the German tribes during a long war from 166 to 180. The pressure from the Goths moving west pushed settled Germanic tribes into invading Roman client states in Gaul, and across the Danube.
The plague raging in the Empire limited Rome's ability to respond. The "Marcomanni" tribe entered Italy, which had not been invaded for nearly 200 years, and defeated the army of the Praetorian Prefect.
This disaster forced Marcus to collect forces from other frontiers, and move them against the "Marcomanni". The Roman army was commanded by Claudius Pompeianus, Marcus' son-in-law, with the future emperor Pertinax as one of his lieutenants. The invaders were thrown out of Italy, and Marcus began planning to cross the Danube into their territory.
Intense diplomatic activity followed, as the Romans tried to win over various barbarian tribes in preparation for a crossing of the Danube. A peace treaty was signed with some tribes, while others became Roman allies. In 172, Marcus defeated the "Marcommani", and in 173 their allies, the "Quadi", were defeated. It took until 174 for the "Quadi" to be subdued.
Marcus was now interrupted by a revolt in the east, led by the Roman general Avidius Cassius. He was suppressed by Marcus' army. Marcus then returned to Rome. A triumph was celebrated with his son Commodus.
