Today my friend and I go to the Nanjing Paleontology Museum. In this museum we learned many things about paleontology. According to scientists, are now living on the earth at about three million kinds of biology, but has appeared at the Earth and eventually the extinction of the biology is far greater than this, in the past forty million years, evolutionary biology is the result, multiply, until the formation of Today is both varied and impressive range of biological species. Living off the Earth at the ancient biology, in part at death was quickly buried in mud, the bodies in the mud deposition in the preserved after millions of years the role of the petrochemical, nuclear biology of effort finally turned into a fossil. Therefore, in order to know the evolution of biology, the most reliable evidence is unearthed from the strata fossils.
When we entered that museum we can see a big Dinosaur Fossils
In front of us. It looks like 10M tell. And than we can see a sign. That sign show me how many parts in this museum. And it gives us a map of this museum. We can find the place where I when to see very easy.
The first part we Visited is Proterozoic. We can see many fossils of Algae and invertebrate. Proterozoic has been self-employed be able to photosynthesis, independent reproduction of blue-green algae type, This is the history of biological evolution of a major development. In the vast sea area, the removal of one-celled blue-green algae, there are floating in the sea algae filaments, accumulation at the seabed and the formation of bread-like algae stromatolites; oval of gray matter nodules also algae rolling at sea, Therefore. Therefore, Proterozoic can be said to be time of algae.
The second part we visited is Cambrian. In Cambrian, In addition to individual categories of things, now living on earth at almost all of biology emerged, opened a biology evolution history of the grand curtain. At that time, the mainland may be desolate, but also did not find any real relic terrestrial biology. Low-level type of moss and lichen plants may live in the humid lowlands, but also the lack of root and fibrous tissue, it is difficult to dry areas sprawl; then invertebrates have not been living in the air function. Shallow water in a wide variety of invertebrates are generally hidden in the various types of algae, the common life, and small organic compounds as food, fertility and reproduction. Cambrian biology, morphology peculiar modern with us on earth to see the very few similarities.
The last part we visited is Ordovician. / Terrestrial plants and animals found in the Ordovician reliable representatives. However, the vast seas, breeding of many of the categories of invertebrates, with the exception of the Cambrian has been generated, some groups also be further developed, such as graptolite, corals, brachiopods, crinoids, bryozoans and molluscs, such as .
By this visited for Nanjing Paleontology Museum, I learned many thing about Ancient Biology. This a good knowledge for us to Learn the past things in our earth.
