The sun is the ultimate source of energy for our planet.Its energy is found in fossil fuels as well as all living things.Archaeologists called these presumed pioneers the Clovis culture, after distinctive stone tools that were found at sites near Clovis, New Mexico, in the 1920s and 1930s.As caches of Clovis tools were uncovered across North America over subsequent decades, nearly all archaeologists signed on to the idea that the Clovis people were the first Americans.Maybe you'd list the Stegosaurus, Brachiosaurus or the saber-toothed cat. Do you think you'd list little guys like Archaeopteryx, Coelophysis or even the humble Compsognathus?It's no secret that our fossil record is chock full of giants.
The enthusiasm everyone shares for these developments has in many ways created a sense of complacency that our future energy demands will easily be met.The story starts around the end of the last ice age, when sea levels were lower and big-game hunters living in eastern Siberia followed their prey across the Bering land bridge and into Alaska.As the ice caps in Canada receded and opened up a path southward, the colonists swept across the vast unpopulated continent. A fossil is the preserved remains or impressions of a living organism such as a plant, animal, or insect. Studying fossils helps scientists to learn about the past history of life on Earth. Collecting Fossils A lot of people like to collect fossils for a hobby. Most fossils are found in sedimentary rock such as shale, limestone, and sandstone.Alternative energy is an interesting concept when you think about it.
