Why aren't the fossils in the Burgess Shale not arranged in an orderly way?

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.

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.
Diversification of animal phyla occurred in the?
Diversification of animal phyla occurred during the Cambrian explosion around 541 million years ago. This event marked a rapid increase in the variety of body plans and structures within the animal kingdom.
What kind of rock is the Burgess Shale formation?
It's the sedimentary rock shale.
Is Burgess Shale a sedimentary rock?
Yes.
Where can carbon fossils be found?
Coal and shale.
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 sedimentary rock often has fossils?
Paleontologists are looking for fossils in sedimentary rock.
What rock type in which you might find fossils?
sedimentary rocks are what fossils are found in
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.
Is shale more likely than sand to preserve fossils?
No, shale is a finer-grained rock and will give better preservation than a sandstone.
Why are fossils more likely to be formed in shale and sandstone than in conglomerate?
Because shale and sandstone don't let water pass them, but conglomerate does
In what type of rack do most fossils form?
A sedimentary rock called shale.
