3 days ago · Europe - Geology, Tectonics, Plate Boundaries: The geologic record of the continent of Europe is a classic example of how a continent has grown through time. The Precambrian rocks in Europe range in age from about 3.8 billion to 541 million years. They are succeeded by rocks of the Paleozoic Era, which continued to about 252 million years ago; of the Mesozoic Era, which lasted until about 66 ...
2 days ago · Europe - Hercynian, Orogenic, Belt: The Hercynian, or Variscan, orogenic belt evolved during the Devonian and Carboniferous periods, from about 419 to 299 million years ago. The belt extends from Portugal and western Spain, southwestern Ireland, and southwestern England in the west through the Ardennes, France (Brittany, Massif Central, Vosges, and Corsica), Sardinia, and Germany (Odenwald ...
4 days ago · The Mesozoic era lasted from about 252 to 66 million years ago and is often called the "Age of Dinosaurs." Dinosaurs were the dominant land animals during this era, and many other new types of plants and animals evolved. The Mesozoic also saw the rise of mammals, birds, and flowering plants. ago and continues to the present day.

1 day ago · During the Mesozoic Era, the age of dinosaurs, and coelacanths diversified significantly, with some species developing unusual body shapes. However, at the end of the Cretaceous Period, around 66 million years ago, they mysteriously disappeared from the fossil record.
3 days ago · Antarctica - Ice, Wildlife, Continent: The geologic evolution of Antarctica has followed a course similar to that of the other southern continents. The earliest chapters in Antarctica’s rather fragmentary record extend far back, perhaps as much as 3 billion years, into early Precambrian time. Similarity in patterns of crustal and biological evolution in the southern continents can be traced ...
4 days ago · Asia - Geologic History: Asia is not only Earth’s largest continent but also its youngest and structurally most-complicated one. Although Asia’s evolution began almost four billion years ago, more than half of the continent remains seismically active, and new continental material is currently being produced in the island arc systems that surround it to the east and southeast.
