The article was written in 2005 so new discoveries could have been found, but the other sources say the same about the topic. The article have not been updated though. Sciencemag is a friendly and easy page to use, and all the links except for one seems to work. The link that does not work is probably just out dated, the only bad thing about that is that is a related source which could mean that some information could have come frok there, but the link is to nasa which is a trustable covermental own site so if some information have been taken from there its fine.

The oceans have some differences from the Jurassic time period and present. The oceans when the  ammonites (A animal that lived in the ocean) lived had a lot warmer oceans than we have present day. Although the marine life during the Jurassic time period, the extinction that happend during the triassic time period only left a few species left, and about half of the marine life. About half way through the jurassic time period had the oceans recovered from the mass extionction in the Triassic time period. Large fishes and sea reptiles lived during this time period. One creatour that lived during this perod was the pliosaur, which are one of the largest carnivals that have been found

One of the top predetors during the Jurassic time period were the Allosauros. Allosauros lived from 155 to 150 million years ago. Allosauros was a big "bipedal" predator, it usully was abot 8,5 m long and up to 12 meters long. Allosauros was att the top of the food chain and usully fed on the big plant eating dinosaurs and other smaller predetors.

From the fossil records and fosil analysis of plants predict that the tropical zone were larger than it is today, and the temperture from the equator and the poles had not as much of a difference. Some analysis from the marine life from the marine life suggest that the avarage watertemperature on the top of the water was about 20°, and the deep water were about 17° which is warmer than it is today. Through the fossil records from the Jurassic time period shows that the first birds comes from this period.
