1. How do fossils form?
noname [10]

Explanation:

There is a LOOOONG process for this so here it is;  

First things first.The animal dies. Soft parts of the animal's body, including skin and muscles, start to rot away. Scavengers may come and eat some of the remains.  Before the body disappears completely, it is buried by sediment - usually mud, sand or silt. Often at this point only the bones and teeth remain.  Many more layers of sediment build up on top. This puts a lot of weight and pressure onto the layers below, squashing them. Eventually, they turn into sedimentary rock.  While this is happening, water seeps into the bones and teeth, turning them to stone as it leaves behind minerals.  This process can take thousands or even millions of years.

I hope this answer helped. Thank you!

Virty [35]

Answer:

Big mammals as bears or Mammoths.

Explanation:

Neanderthal had a diet based in different food, for example, there are some evidence that they were feed on nuts, mushroom, and moss. The quantity of veggies were different depending the season and the region of the planet the neanderthals were.  Of course, most of their diet were based in meat, basically  of big animals because the evidence is that they had a digestive system appropriate to eat lean protein.

Studies of the bones and the coprolites showed a ratio of different elements as nitrogen and carbon, the ratio of the heavier element to the lighter, show the relationship among the meat/vegetable diet.

Hope this info is useful.
