What is the maximum depth at which fossils are found in the earth's crust?

They are mostly found on, or very near, the surface. They have probably been quite deeply buried at some point ( a lot can happen in, say, 70 million years) but due to tectonic movements and erosion, they finish up where we can find them. If all the Jurassic rocks were buried at about 300m, then our knowledge of dinosaurs would be impressively small.

∙ 13y agoIt depends on where the rock is situated, some fossils are found at the surface, some are found up mountainsides, others are found deep in coal mines.
Most fossils are found near the surface as it is easier to find them there.

∙ 13y agoThe maximum depth in a certain area would depend greatly on the geothermal gradient of that area and the composition of the sediment, as sedimentary rock will have a temperature/pressure threshold in which it starts to recrystallize and form metamorphic rock. Because fossils are found mostly in sedimentary rock, the maximum depth of sedimentary rock on Earth would also be the maximum depth at which fossils could be found. The deepest deposits of sedimentary rock on Earth are more than 20,000 meters below the surface (over 12 miles) in the Gulf coast region of North America. This is probably the maximum depth at which fossils can be found in the Earth's crust.

Why are animal fossils more abundant from the Cambrian Period than from the earlier periods?
Because Paleozoic era rock is much older than Mesozoic era rock, these strata are generally at greater depth than Mesozoic rock, thus limiting their accessibility to areas that have been exposed by weathering and erosion.
What materials are found in the earth's crust?
The earth's crust is made up of several elements: Silica, Calcium, Oxygen, Iron, Sodium, Aluminium, Manganese and so on. These elements combine in some form or other to make salts like Silicon-oxide, Calcium carbonate, Iron-oxide for example which are known as minerals and several minerals combine to make rocks. The distribution of rocks and minerals across the different parts of the globe is different, and hence geologist study different rocks/lithologies across the globe. And also this distribution will changes with depth. The upper crust has different elemental composition with respect to the lower crust. For example, the upper crust has more of aluminum with respect to lower crust whereas the lower crust ahs more Magnesium with respect to upper crust.
What layer in the atmosphere has the lowest temperature?
The Mesosphere has the lowest temperature of the layers of Earth's atmosphere because Temperature decreases with height in the mesosphere. The mesopause, the temperature minimum that marks the top of the mesosphere, is the coldest place on Earth and has an average temperature around −100 °C (−148.0 °F; 173.1 K)
What are earths mechanical layers?
Lithosphere (apex)

How much depth below the earths surface is the crust?
The depth of the crust varies between 10 and 70 km in different areas, depending where you would measure it.
What is the depth of the earths crust in cm?
4 million approx, 40 killometres = 40,000 metres x 100 = 4 million centimetres
What is the approximate depth of the crust?
Oceanic crust is roughly 4 miles in average depth. Continental crust is on average 25-30 miles in depth.
What is the layer of earth beneath the crust called?
The layer of the Earth below the crust is called the mantle. The mantle is the thickest layer of the Earth with a depth of 2,890 kilometers.
How does temperature change with depth in Earth's crust?
The temperature increases with increasing depth within Earth's crust.
