What did the earth's surface look like in the Jurassic time period?

Answer 1

During the Triassic, almost all the Earth's land mass was concentrated into a single supercontinent centered more or less on the equator, called Pangaea. From the east a vast gulf entered Pangaea, the Tethys sea. It opened farther westward in the mid-Triassic, at the expense of the shrinking Paleo-Tethys Ocean, an ocean that existed during the Paleozoic. The remaining shores were surrounded by the world-ocean known as Panthalassa. All the deep-ocean sediments laid down during the Triassic have disappeared through subduction of oceanic plates; thus, very little is known of the Triassic open ocean. The supercontinent Pangaea was rifting during the Triassic-especially late in the period-but had not yet separated. The first nonmarine sediments in the rift that marks the initial break-up of Pangaea-which separated New Jersey from Morocco-are of Late Triassic age; in the U.S., these thick sediments comprise the Newark Group. Because of the limited shoreline of one super-continental mass, Triassic marine deposits are globally relatively rare, despite their prominence in Western Europe, where the Triassic was first studied. In North America, for example, marine deposits are limited to a few exposures in the west. Thus Triassic stratigraphy is mostly based on organisms living in lagoons and hypersaline environments, such as Estheria crustaceans.

At the beginning of the Mesozoic Era, Africa was joined with Earth's other continents in Pangaea. Africa shared the supercontinent's relatively uniform fauna which was dominated by theropods, prosauropods and primitive ornithischians by the close of the Triassic period. Late Triassic fossils are found through-out Africa, but are more common in the south than north. The boundary separating the Triassic and Jurassic marks the advent of an extinction event with global impact, although African strata from this time period have not been thoroughly studied.
some what like panagea

Answer 2

In the beginning of this period, the earth's surface area that lied North of the Tropics was mostly ocean and seawater. The earth's land mass was located altogether in a super-continent in the Southern region. This super-continent was called Gondwana.

During this period, Gondwana eventually moved towards the South Pole. Most of the land mass became submerged underwater. Finally, by the later part of the Ordovician, this event led to the formation of huge glaciers, which caused some seas to emply entirely of their water, and eventually causing the dropping of the earth's sea levels.

Answer 3

Noone knows for sure just how it looked, but scientists have collected fossils of animals and plants from the Jurassic. But DO NOT judge from the movie Jurassic Park. That movie has all kinds of errors.

Answer 4

The Jurassic Period was very lush with vegetation. It had humid, subtropical climates. During this period, the process of continental drift was accelerating and the super continent Pangaea was continuously breaking up. By the late Jurassic, Earth's surface was divided into 2 major continents and 2 major oceans. The major continents were Laurasia, to the north, and Gondwana, to the south. Laurasia consisted of North America, Europe and Asia; Gondwana consisted of South America, Africa, India, Australia and Antarctica. The major oceans consisted of the Pacific Ocean in the Western Hemisphere and the Tethys Ocean in the eastern hemisphere. The vegetation of the Jurassic Period included conifer forests in the polar regions and the spreading of ferns, cycads and conifers in the tropics. ~ NightShade ~

Answer 5

The Devonian refers to a geologic period and system of the Paleozoic Era. It was a relatively warm period that lacked glaciers. There was also great tectonic activity during this time, as Euramerica and Gondwana drew closer together.

Answer 6

I think that the earths surface was one giant super Continent surrounded by H2O

Answer 7

During the devonian time period most of land was under water.

Answer 8

Very lush humid sub tropical areas

Answer 9

water covered most of the surface
