Fossils room the an effect of one extremely unlikely fluke ~ another. Darwin self commented on this. It takes just-right circumstances to have the bones of a freshly deceased pet not be consumed by scavengers or turned into rot by bacteria. The takes yet another collection of just-right circumstances for those bones to turn right into fossils. The takes yet another collection of just-right situations for those fossils to it is in brought back to surface ar level. The takes however one an ext set the just-right situations for those practically exposed fossils to make it through the ravages that time and also weathering.
You are watching: What are the two best environments to look for fossils
The last coincidence is where deserts come right into play. Water is one extremely powerful weathering agent. The key characteristic the deserts is an extreme lack the water. Fossils room much more likely to endure the savages the time without that weathering by water.

Because you find fossils through looking at exposed bedrock, deserts by their nature regularly have substantial expanses the exposed bedrock. The absence of tree is also a huge benefit, tree roots have tendency to ruin fossils
Fossils are almost everywhere you have sedimentary rock* deserts room actually rather poor at developing fossils compared to numerous other environments. They room FOUND an ext often in deserts because there room no tree or soil spanning them up and also no tree roots come rip castle apart because that minerals. You do not require deserts just exposed bedrock. Store in mental what are deserts now, were rarely deserts as soon as the fossils to be buried, her own examples of localities were estuaries, floodplains, and also shallow seas respectively and are places far more likely to form fossils.
Fossils in other climates are frequently found during road cuts, mining, or big building projects, cases where every the soil is removed exposing bedrock, i m sorry of course renders searching the bedrock possible. In many deserts the radical is already exposed definition all you have to do is wander about until you uncover a fossil poking out. That is far simpler to just wander about a patch of desert and search through your eye then dig up random portions of a forest hoping to find fossils. Searching for fossils is almost always visual, which way you require to be able to see the ground and not plants extending the ground. Return in deserts you can use plants, if you see a broad expanse of open up desert soil and a solitary plant, unless there is a water resource that plants roots are frequently wrapped around a fossil, the added minerals indigenous the fossil help the tree grow far better than those approximately it, tree roots are really destructive and tend to seek out fossils.
The finest environments for creating fossils are frequently wet, floodplains, estuaries, and also lakes are good for developing fossils since they have actually a most deposition and also the first step in fossilization is burial. Deserts which regularly have small sedimentation are pretty negative at developing fossils, yet they make searching for them so lot easier. Quite frankly there space not many paleontologists and they are human, so they tend to hit locations with high possibilities of detect things.

there is one various other factor, human being often don"t choose paleontologists digging increase their property or slowing under construction, but people or governments that own stretches of desert regularly don"t treatment if you destruction up portions of it. So in the desert lucky finds will get increased exposing an ext and more of the appropriate layer, while in other settings this would not be economically or legit feasible.
examples of famous non-deserts, Solnhofen Germany a gigantic limestone mine, La Brea tar pits, hell the first complete fossils skeleton ever discovered was discovered in brand-new Jersey in a coal mine.
**Not every sedimentary layer has fossils, over there is a geochemical and also physical factor, but a surprisingly huge number do.*
