The Mudstone was packed so tightly around the fish that moisture, warmth and oxygen could not reach it and begin the process of decay. This is why most fossalised fish found in Mudstone are still intact with skin and bone!
mainly high pressure but you'll also need sediment such as rock or sand to smash it and as the soft parts of the plant decay they leave impressions on the rock
It's when the rock dies and is attacked by decomposers. This is why it has a small chance of becoming a fossil, but if it does, it gets covered by sediment where it slowly starts to decay. The rock then starts to be preserved where the first layer of sediment is compressed by the weight.
When Algae runs out of the proper nutrition it needs such as phosphates and other minerals it dies. Algae then dies and starts to decay during the decaying process Algae uses oxygen which is also why fish die from lack of oxygen. So to answer this question yes Algae does decay and consume oxygen.
Things that don't decay (or that don't decay quickly) are difficult to digest, for bacteria.
when plants and animals break/ decay there release chemicals from there bodies which breaks down rocks also the roots of plants sometime penetrate through the rock causing it to crack
Mudstone is a clasitc sedimentary rock.
Mudstone is a clastic sedimentary rock.
No. Mudstone is sedimentary rock, but not all sedimentary rock is mudstone. Sandstone and limestone are other common varities of sedimentary rock.
Mudstone is the fine grained sedimentary rock that were clays or muds originally.
mudstone has smaller particles :D
Mudstone is a mudrock. It is made of clay minerals and other very small pieces of rock. Mudstone is sedimentary.

Mudstone or shale.
Mustone is a clastic sedimentary rock, not a mineral.
Mudstone, claystone, and siltstone.
