The remains of Zhongsaurus, a freshwater crocodile-like reptile, lived in the early Permian (286 to 258 million years ago), only in the Southern Africa and Eastern South America.

Which two continents contain fossils of Sinosaurus (an extinct reptile) and similar areas of Pangaea?

answer: Africa and South America.

Which two continents have fossils?

South America and Africa Contains animal fossils found only on these two continents, with corresponding geographic ranges. One of these animals—an ancient freshwater reptile called a mid-saurus—couldn’t have crossed the Atlantic.

How does the dragon move?

probably pushed It crosses the water on its own with its long hind legs and nimble tail. Its body is also flexible and can easily move sideways, but its ribs are much thicker, which prevents it from twisting. Zhongsaurus had a small skull and a long jaw.

In which era can the oldest fossils be found?

the oldest is Paleozoic, meaning « ancient life ». Fossils from the Paleozoic include plants and animals that were either completely extinct (such as trilobites) or rare (such as brachiopods) in the modern world.

Why does no one believe Wegener’s theory?

The main reason why Wegner’s hypothesis is not accepted is that Because he suggested that there is no mechanism for moving continentsHe thought the force of the Earth’s rotation was enough to move the continents, but geologists knew the rock was too strong for that to be possible.

What was the reaction to Wegener’s hypothesis?

« He always answered: assert it again, even stronger. By the time Wegner published the final version of his theory in 1929, he was convinced that it would sweep other theories aside and bring together all the accumulated evidence into a unified vision of Earth’s history.

How fast did Pangea break up?

This was most pronounced between North America and Africa during the initial rifting of Pangaea around 240 million years ago.At that time, the slabs that carried these present-day continents were One millimeter per year. They stayed in this slow phase for about 40 million years.

What is the evidence for Pangea?

Glacial deposits of the same age and structure have been found on many different continents, especially until, when these continents would have been clustered together on Pangaea. Fossil evidence of Pangea includes Similar and identical species now exist on widely separated continents.

What are examples of fossil evidence from Pangaea?

Four fossil examples include: Mesosaurus, Cynognathus, Lystrosaurus and Glossopteris. A modern representation of Zhonglong. Zhongsaurus is known to be a reptile, similar to a modern crocodile, that propelled itself through the water with its long hind legs and soft tail.

Which three continents have coal fields?

. the answer is Eurasia, North America, Africa and South America. Most of the world’s coal fields are located in these countries, with high-quality coal fields located in Africa and South America.

What does pangea mean in Greek?

Surrounded by a global ocean called Panthalassa, Pangaea was fully assembled during the early Permian period (about 299 to 273 million years ago). …it takes its name from the Greek pangaia, which means « The whole earth. « 

What are the 4 evidences of continental drift?

Evidence of continental drift includes The fit of continents; the distribution of ancient fossils, rocks, and mountains; and the location of ancient climate zones.

What is the force that drives the continent?

The motion of these tectonic plates is likely caused by convection in molten rock in the mantle below the crust. Earthquakes and volcanoes are short-term consequences of this tectonic movement.long-term results plate tectonics is the movement of the entire continent over millions of years (Figure 1).

Why is Pangea not accepted?

Despite this geological and paleontological evidence, Wegener’s theory of continental drift was not accepted by the scientific community because His explanation of the driving forces behind the continental movement (He said it stemmed from causing the Earth’s equatorial bulge or…

What is Wegener’s theory?

Alfred Wegener of Greenland.Plate tectonics are The theory that the earth’s land masses are in constant motion. Alfred Wegener first proposed the understanding of the movement of the earth’s land masses, which he called continental drift.

Which two continents separated from Pangea?

Pangea began to split and split into two major continents – Laurasia in the north, consisting of North America and Eurasiaand Gondwana to the south, which consists of other continents.

Who came up with the theory of seafloor spreading?

Harry Hess: One of the discoverers of seafloor spreading.

What is the main problem with Wegener’s thought?

The biggest problem facing Wegener is Lack of direct evidence of continental movement (There was no GPS at the time!) And no known mechanism was powerful enough to move an entire continent.

Is it a supercontinent?

In geology, a supercontinent is A collection of most or all land masses or cratons on Earth, forming a single land mass. . . The supercontinent Pangea is the general term used to describe all the continents when they have come close to each other recently.

What is the youngest fossil?

Yale University scientists have discovered what is believed to be the youngest dinosaur fossil ever discovered in the Hell Creek formation in Montana, according to a study published in Biology Letters.It is understood that this 45 cm horn comes from Triceratops.

Where can most fossils be found?

Most fossils are found in sedimentary rock. Sedimentary rocks are formed from mud (sand, silt, or clay) and debris deposited on the bottom of oceans or lakes, compressed over a long period of time, and become as hard as rock. Limestone and sandstone are types of sedimentary rocks that often have fossils.

Where are the oldest fossils usually found?

The oldest fossil on earth has been found in AustraliaThese microscopic fossils provide compelling evidence for cells and bacteria that lived in an oxygen-free world 3.4 billion years ago. A team from the University of Western Australia and the University of Oxford has discovered the oldest fossils on Earth in Australia.
