jurassic era?

Question

describe the plants that existed during the jurassic era and also describe the life

Answer 1

The Jurassic *Period* is a time period that is part of the Mesozoic Era. The earliest part of the Mesozoic was the Triassic Period, followed by the Jurassic Period, which was followed by the Cretaceous Period.

This was an interesting time in Earth history. Here is a paleogeographic map of the Jurassic time:

You can see that South American and Africa, as well as Antarctica are all part of one continent in the Late Jurassic. The predecessor of the Atlantic Ocean, the Tethys Sea is a narrow sea separating two large continents, and North America and Eurasia are almost connected. These differences in the continental geography would have affected climate in the Jurassic by creating different ocean currents and weather patterns than the world has today.

Conifers were the dominant plant species, followed by Ginkgos. Mesozoic conifers include redwoods, pines, and cypress, which are all represented today. Ginkgos are a deciduous tree which lose their leaves in cold seasons, and have one surviving species today. Ferns and club mosses were also common plants. To see some sketches of these plants and read more visit:

Animal life of the Jurassic is also described on that website.

One interesting fact about plant life in the Late Jurassic Period is that this is when the first flowers emerged. Plant life changed dramatically, and most plants we know today did not exist prior to this evolutionary development.

Answer 2

I think you are not getting many answers because your question is so broad. But here's a good start: http://www.palaeos.com/Mesozoic/Jurassic/Jurassic.htm
I wasn't planning to answer this question but when I saw the only answer you had was from a religious fundie, I had to reply. Most of his comments simply aren't true. It's hard to tell whether these people believe what they are saying or are just repeating the dogma of their religious authority without any thought at all. Keep in mind, they think they are doing the work of God by defending his holy scripture. So they will lie and deceive with great pride. IOW, sanjaya-blows blows it out his butt.

Answer 3

no such thing as the jurassic era. the world is only 6,000 years old. don't believe everything you read in school. there is no reliable evidence proving the earth is billions of years old. all types of dating methods yield widely varying results (several billion years off between methods). carbon dating is also very unreliable after a short period of time. everything was buried all at the same time during the flood that wiped out the earth. archaeologists will tell you these are different eras of time when in fact you find whole 60-100 foot trees buried in sediment that span several "thousand years" according to this ideology, which is completely untrue. There is no fossil evidence for evolution either. Read up on radio isotope dating of the earth using the included link.

Answer 4

Two words: Doctoral Dissertation. The question you asked could fill a text book.

Answer 5

Conifers, cycads, gingko, ferns, horsetails. Reptiles, amphibians, fish, crocodiles, dinosaurs and a few mammals.
