Sedimentary rocks. This is a type of rock that is formed by sedimentation of material at the Earth's surface and within bodies of water. Example: sandstone, limestone, conglomerate, and shale.
They can be found in several types of Rock. The obvious one is sedimentary rock. Metamorphic: But what about when that rock gets lightly metamorphosed. When limestone is altered to Dolomite you can still see the fossils. When limestone if turned into marble, you can still see some of the fossils. If the rocks get highly metamorphosed, then the fossils get obliterated. Igneous: You can find foot prints and casks in ash falls. Also, what about the full body casks found at Pompeii and Herculanium. So you can find fossils here too. In Hawaii, lave flows around trees. When the lava cools, you can see the holes the trees made. These are fossils also. You are not limited to one type of rock. The correct answers are Sedimentary, and in some cases Metamorphic and Igneous.
the three substantial forms of rocks are igneous, sedimentary, and metamorphic. Igneous rocks are shaped by employing the hardening of lava or magma or different volcanic tactics. existence varieties whose remains fell into lava or magma would not strengthen into fossilized that they had purely dissipate. even although, while volcanic ash is deposited (from a volcanic blast), it may seize lifeforms and later type into rock. Sedimentary rocks are shaped while sediment (like sand or silt) is compressed and turns into rock. If a lifeform's remains have been lined in sediment, it ought to strengthen into fossilized in that rock. maximum fossils are present in sedimentary rock for that reason. Metamorphic rock is shaped while an present rock is heated and under pressure by employing rigidity deep interior the earth's crust. If a sedimentary rock containing fossils is converted to metamorphic rock, the fossils may be preserved, even though stretched or compressed, or the fossils could additionally be destroyed. So - fossils may be present in all 3 substantial rock types, even though they are maximum ordinarily present in sedimentary rocks. inspect the hyperlinks for extra information.
