The Burgess Shale fossils are a group of shallow water living creatures which found themselves in an underwater avalanche. The avalanche deposited them in deep water which was probably anoxic, (no oxygen), and this would have killed them in whatever position the avalanche left them.
What else can I help you with?
Do fossil form in shale or halite?
Fossils could form in shale. Halite is table salt, a mineral with a crystalline structure that is not compatible with understood fossil formation methods.
Can scoria hold fossils?
Schists are formed when a sedimentary rock is deformed by great heat and pressure, deep within the Earth's crust. This deformation means that fossils do not survive in schists. Only less deformed rocks, such as slate and shale, can hold fossils.
What is a dark sedimentary rock formed by compression of layers of clay-rich sediment?
Shale is made from layers of mud and clay pressed together. :)
In which type of rock are fossils least likely to occur?
Fossils would not likely be found in rock other than limestone, sandstone, and shale, or rock such as marble that has morphed from these sedimentary rocks. Fossils can basically be find in most Sedimentary rocks, but not in Igneous rocks because they are formed in volcanoes.
What layers of sedimentary rock can be found in fossils?
Think of the layers like leaves of a book. The further you go back in the book is farther back in time. The layers show drought, floods, fires, and other things that happened in time. They are piled on top of each other. So, the further back you go the more apt you are to find fossils. Location also has a great deal to do with it.
Is Burgess Shale a sedimentary rock?
Yes.
What sedimentary rock often has fossils?
Paleontologists are looking for fossils in sedimentary rock.
Do fossil form in shale or halite?
Fossils could form in shale. Halite is table salt, a mineral with a crystalline structure that is not compatible with understood fossil formation methods.
What rock may you find a fossil in?
Shale sometimes holds fossils. =]
The rock that is rich in plant fossils?
Coal, and to a lesser extent, shale.
What kind of rock is the Burgess Shale formation?
The Burgess Shale formation is a fossil-bearing geological formation made up of layers of shale rock. It is located in the Canadian Rockies and dates back to the Cambrian period, around 505 million years ago. The formation is known for its exceptional preservation of soft-bodied organisms from the early stages of animal evolution.
Where can you find fossils from the cambrain period?
There are a few notable dig sites that have very well preserved fossils from this period. The best sites of the Cambrian period are:Maotianshan Shales (Chengjiang) 515 Mya Yunnan Province, China Sirius Passet 518 Mya Greenland Emu Bay Shale 513 Mya South Australia Kaili Formation513-501 Mya Guizhou province, south-west China Blackberry Hill~510-500 Mya Central Wisconsin, US Wheeler Shale(House Range) 507 Mya Western Utah, US Burgess Shale 508 Mya British Columbia, Canada Kinnekulle Orsten and AlumShale 500 Mya Sweden ÖlandOrste and Alum Shale 500 Mya Sweden
Is shale more likely than sand to preserve fossils?
No, shale is a finer-grained rock and will give better preservation than a sandstone.
What rock type in which you might find fossils?
Sedimentary rocks are the type in which fossils are most commonly found. This is because they are formed from layers of sediment, which can entomb and preserve the remains of plants and animals over time. Examples of sedimentary rocks where fossils can be found include limestone, sandstone, and shale.
Why is the Burgess Shale important?
The Burgess shale located in field British Columbia Canada is one of the greatest collections of Cambrian fossil life gathered in one place anywhere on earth. It is thought that these creatures may have met their ends due to a gamma ray burst, but this is still just a theory.
What rock contain fosils?
Quite often, fossils are contained within shale rock.
What are the characteristics of format?
Formations consist of strata of specific origin, type, or characteristics. Mostly sedimentary, a formation could also be of metamorphic or igneous origin. One of the most famous formations is that of the Burgess Shale, a treasure trove of Cambrian age fossils, located in the Canadian Rockies.
