What is Burgess Slate?
Burgess Shale is a collection of very well -preserved fossils from the Cambrian period, from about 550 to 480 million years. It is located near Burgess Pass, high in the Canadian rock in the province of British Columbia. Although they were discovered in 1909, only in the 1880s. The black slate in which these organisms are preserved, from which the name of the slate gets its name, has an extremely fine grain size, allowing high -quality fossils and even fossilization of organisms lacking hard shells. Burgess Slate is known for what she told us about Cambrian explosion, a time in an early Cambrian, when all the main phyles of life appeared in a paleontologically negligible time was only a few years. Others come from more exotic phyla, such as Halucigenia Sparsa , which is a member of Phylum Onychophora, which includes modern velvet worms. Halucigenia , named after its bizarre, hallucinating lookU, a rod creature with different spikes protruding perpendicular to its axes in different directions. Opabinia is a difficult to classify organism with five eyes and flaps similar to a flap terminated by a mini-application or drapt with teeth, a trailer that has no other known animal.
trilobites were found in large quantities within the Burgess slate, as well as nectocaris , unusual streamline animal, which has certain characteristics of vertebrates and other arthropods, making it a nightmare for biological taxonomics. In general, Burgess's slate is responsible for the production of most difficult samples in early fossil record.
Perhaps the most famous of the organisms of the slate of the burgher slate is anomalous -pro , the world's first apex predator in the world, whose name means "anomalous shrimp", which has grown to a huge 2 m for time, all the time. Floated with water using flexible lAllocations up and down by his side and using two grabs located near his mouth to catch the prey and put it in. His mouth Bizzare resembles a slice of pineapple, with sharp spines all around the edges. anomalocaris also had some of the most developed eyes for any organism existing at that time.
Today, this task is still dugting the slate slate and finding the biological miracles it offers. Some of the organisms contained in them are so rare or fossil enemy that there are only individual samples, which limits our knowledge of the species. Further investigations could discover new surprises for biology that we can now speculate about.
