Fossils and dinosaurs
Hi! My name is Andreas, and I would like to tell you all about fossils and dinosaurs. The science of fossils is called paleontology .
Fossil remains of plants and animals are fantastic evidence of past life on our planet. Mostly, they are found in sedimentary rocks . But how did they get there? Actually, becoming a fossil is very difficult process that requires a rare combination of circumstances:
The Ammonite bobs around happily in the sea.
but then dies and falls to the seabed.
soft parts decay, leaving the shell, buried in sediment.
but then, under the action of hot water and pressure over millions of years it becomes.
in the fossil that you find at the beach!
There are lots of different types of fossil, including parts of skeletons, shells, footprints, moves done loadname worms, the remains of shellfish, etc. Most fossils we find today are the remains of mainly marine life. This is due to the fact that they were buried in sedimentary rocks before all traces of them disappeared!
Learn about some sea creatures whose fossil remains we find regularly:
On the map of Afghanistan rocks of the Jurassic period are shown in brown. Perhaps,in these places you can find fossils of dinosaurs!
Creatures that lived on land, also could turn into fossils, but this happened less often. Dinosaurs — a perfect example of that. They lived 230 to 65 million years ago, and their fossils are still found all over the world.
The biggest fossil dinosaur Brachiosaurus found in Tanzania. Its height is 12 meters and the length of 22.5 m.
The longest fossilized dinosaur reaches 27 m. This is Diplodocus. discovered in Wyoming, USA.
The smallest dinosaur fossil is about the size of a chicken and a wingspan of 55-75 cm was found in China. This Is A Microraptor .
Fossils help to draw up a geological map . which inform us about the age of rocks. Scientists have found that creatures that inhabited the Earth at different times, look different – they have evolved and adapted to new conditions of life. So, if we find the same fossil in two different species, we know that these rocks have the same age!
For more information
Fossils, especially those unique instances that are stored in museums are a wonderful reminder of the age and diversity of life on our planet.
Most minerals that we can find on the beach or in quarries that are not in the best condition, usually they are damaged during your stay at the rock, but they contain extremely important information, as are the direct witnesses of past life on our planet.
Bones, shells, footprints or tunnels of worms and molluscs, are clues left by animals, so we can reconstruct their way of life.
These tips can be used to restore the way of life of fossil animals and plants. Fossils can tell us about the temperature of the water in the sea, in which swam, or to serve as proof of the existence of ancient oceans, which have by now disappeared.
The study of these illustrative examples of the evolution allows us to create a picture of the life history of our planet and the great evolutionary forces which have changed the world.
