• Mesosaurus was an extinct lizard that lived around 265 million years ago, was 3 feet long, had webbed hands and feet, and lived on land but hunted in freshwater.
• Lystrosaurus was a large lizard about the size of a pig that was found in Africa, India, and Antarctica around 250 million years ago.
• Eduard Suess was an Austrian geologist who found fern-like tree fossils in 1824 and named it Glossopteris, which grew 12 feet tall and had tongue-like leaves, with 70 different species.
• Glaciers are large, slow-moving solid bodies of ice that are very thick and very heavy, and as they move, they cause friction along the bottom where the ice meets rock, crushing, scraping, and moving rocks similar to a river.
• Glaciers can cause large, wide valleys to be carved and move less than 1.6 km per year.
• Wegener found that much of North America was covered in ice 300 million years ago, along with South America, southern Africa, India, and southern Australia.
• Antarctica is an extremely cold and inhospitable continent, but coal is found there, indicating that it was once a warmer climate.
• South America and Africa appear to fit like a puzzle, with layers of rock similar from oldest to youngest: Basalt, limestone, coal, shale.
• Continents seem to fit together like a puzzle.
• South America and Africa appear to fit like a puzzle, with layers of rock similar from oldest to youngest: Basalt, limestone, coal, shale.
• Wegener proposed that North and South America and Africa were once connected and there was no ocean between them.
• Mesosaurus had similar living habits to a present-day crocodile.
• Fossils of Mesosaurus have been found in South America and southern Africa.
• Lystrosaurus was a large lizard about the size of a pig that lived 250 million years ago, was found in Africa, India, and Antarctica.
• Eduard Suess was an Austrian geologist who found fern-like tree fossils in 1824 and named it Glossopteris, which grew 12 feet tall and had tongue-like leaves.
• Glossopteris was a deciduous plant that lost its leaves.
• Glossopteris thrived in a temperate climate and was found in South America, India, Australia, Africa, Antarctica, Madagascar.
• A glacier is a large, slow moving solid body of ice that is very thick and very heavy.
• Glaciers cause friction along the bottom where the ice meets rock, crushing, scraping, and moving rocks similar to a river.
• The underlying rock becomes weathered and eroded as glaciers move.
• Glaciers can cause large, wide valleys to be carved.
• Glaciers move less than 1.6 km per year.
• After melting, scientists can determine the direction that the glacier moved by looking at grooves called striations.
• 10,000 years ago, during the last ice age, ice can be 1.6 km thick.
• Wegener found that much of North America was covered in ice 300 million years ago, as well as South America, southern Africa, India, and southern Australia.
• Antarctica is extremely cold and inhospitable.
• Coal is formed from decomposed plant matter and coal is found in Antarctica.
• Swampy plants associated with coal are not found in Antarctica now.
• Animal fossils are also found in Antarctica that would not be able to survive this climate, indicating that the climate in Antarctica must have been warmer at one time.
• Continents seem to fit together like a puzzle.
