Ancient Continents South of the Equator
A supercontinent is a bunch of continents in one. The first supercontinent was Godwana was located near the South Pole.
Ice Cap Covers North America
Ice caps and glaciers are the same thing there both a thick layer of ice and snow. Ice caps cover fewer than 19,000 square miles. Glacial ice covers more than 50,000 square kilometers.
Appalachian Mountains Form
300 million years ago, when Euramerica continent smashed into Godwanaland, that pushed the land together to form the Appalachian mountains.
Pangaea Forms
280 million years ago Pangaea formed. Pangaea was a supercontinent where all the other continents pushed together and made a supercontinent. Later, the continents that made Pangaea up broke up and emerged away from eachother this still happens today.
Vertebrates Arise
Fish started to develop over 500 million years ago. It took many years for fish to start to develop bones.
Plants on Land
540 million years ago plants evolved from algae. Most animals were still fish living in the water, on land there was only moss and mushroom.
Lungfish
400 million years ago, the earth was going through a very warm period of time with some bodies of water drying up. They had muddy puddles but they were worried that they would fall in and get stuck they would suffocate from the thickness of the mud. lungfish were able to solve both those problems. They began to use there swim bladders to breathe with, and doubled there bones to easily glide through the thick mud.
Insects
Bugs have been around a lot longer than humans. In fact, fossils of fish have been found and proved that they were from 400 million years ago.
Amphibians
Frogs, toads and salamanders have been around since the Jurassic period.
Reptiles
The earliest known reptile is Hylonomos Iyelli. Hylonomos was discovered in in 1852 by Sir William Dawnson. Reptiles have scales and four legs.
Paleozoic Mass Extinction
The permian period is the final period of the Paleozoic era. It started 290 million year ago and lasted 248 million years.
