They are a destination for recreational boaters and fishermen. Tourists spend billions of dollars in the eight states and two Canadian provinces that share the lakes’ 10,000 miles of shoreline. What happens when continents collide? - Juan D. Carrillo. The configuration of the continents has changed during the earth history because of different geologic processes that in turn shaped the natural world.

What happens when continents collide? - Juan D. Carrillo

At the scale of millions of years, we are able to recognize that the evolution of the earth’s geographic features and plate tectonics have a strong impact on animals, plants and climate. During the Cenozoic, the time period after the extinction of the dinosaurs, South America was isolated from other continents. Here you can explore some paleogeographic global reconstructions at different times of earth history. At that time South America was the home of an endemic fauna. Do the words notoungulate and isotemnids make you wonder what these animals looked like? The northern continent had its own, different, fauna, with animals more familiar to us such as horses, bears, and saber-toothed cats. North and South America were separated by a marine connection between the Pacific and Atlantic oceans. Quick Overview Geologic Time Scale.

Share By Rima Chaddha Posted 11.01.07 NOVA In 2004, scientists digging in the Canadian Arctic unearthed fossils of a half-fish, half-amphibian that all but confirmed paleontologists' theories about how land-dwelling tetrapods–four-limbed animals, including us–evolved from fish.

It is a classic example of a transitional form, one that bridges a so-called evolutionary gap between different types of animal. In this slide show, examine five important cases.

As animals and plants evolve (change over time), some groups die out - become extinct - as the dinosaurs did 65 million years ago.

The History of Life

New groups have also appeared, like the birds, which evolved from dinosaurs. Palaeontologists use the extinction and appearance of different groups to define geological periods. If you put all the geological periods together you have constructed a geological timescale. The geological timescale records changes in the fossil record. Click on the geological periods on the timescale to see which groups of plants and animals were alive in each of them.

The scale helps us understand geological time. Discover the history of life in these pages. Top 10 EXTREME Prehistoric Creatures! Ss1106 14. Fossil Inferences. Summary Students will use their knowledge about fossils to arrange fossil pictures in sequence from oldest to youngest.

The study and comparison of exposed rock layers or strata in different areas of Earth led scientists in the early 19th century to propose that the rock layers could be correlated from place to place.
