Scientists have discovered the wealth of well-preserved fossils at the beginning of Cambrian by replacing 101 species to date, and more than half have never been described.
In 1909, scientists discovered fossils of fossils. Fossils do not differ from those that kept the soft matter structures, revealing things such as eyes and guts or soft animals like jellyfish.
Burgesses shale have found fossils all over the world and scientists have contributed to contributing to the emergence of Cambrian times around 500 million years ago and around it. Cambodia explosion
The newest discovery of the Danshui River, called Qingjiang biota, competes with existing fossil associations, which maintains the diversity of species and the proportion of new species.
"The great proportions of the new bijou taxon in Qingjiang … suggest that the ecosystem's inequality and inequality of metazoans are far from being understood by the ecosystem of the Cambrian explosion, and future discoveries will be greatly informed." Writers from Northwest University and Guizhou University of China and Pomona College published this week They write in the article Science.
According to the article, fossil editing describes 4,351 specimens, 518 million years ago. Of the 101 newly identified species, 53 new percentages and 85% were smooth.
The most numerous groups include arthropods (invertebrates, spiders and crustaceans) and sponges. Fossils are in the sea, sea sediments, and swim like meditations.
Surprisingly, only eight species were distributed from Chengjiang's biot, as well as Burgess shale-type fossils, at 1050 km. These differences are astonishing, but it is likely that the ecological difference in two places is 518 million years ago.
"Two comparisons of the biota offer rare options to how to respond to environmental parameters by how the first meta-community communities have evolved," writers say.
For other reasons, it is also an exciting discovery.
"Cnidarianes, corals, sea anemones and jellyfish are quite rare and are not particularly variable in the explosion areas of Cambodia, but the Qingjiang biography shows a great deal of abundance and diversity, since more than a third of these issues are made up", Allison Daley of Lausanne University Swiss Associate Professor of Geochemistry, from the perspective of research Science.
"Free swimming is accompanied by jellyfish and anemones attached to the sea and with specific anatomies that are immediately known".
These include fossil discoveries as exciting as the rest of the Cambrian period. The authors write "Qingjiang and elsewhere, there is a great deal of potential for continuing the discovery of new provincial taxes".
The site is an important photo on the Cambrian explosion. It began some 542 million years ago when a large number of fossil records appeared. At this time, the beginning of many interactions with marine animals that exist today.
