There is nothing living in/on molten lava.
You can find fossils in volcanic tuff, but that is volcanic ash that falls on things then fuses into a solid but soft and lightweight rock.
fossils almost allways occur in sedementary rock. this is the only way to get fossils without burning or cruching the fossil. you sometimes get fossils in igneous rock, but this is very rare. igneous rock fossils do not have any actual "fossils" in them, they are just impressions.
No. There are two reasons for this.You generally do not find fossils in volcanic rock.Aruba formed after trilobites went extinct.
If a lava flow or bed of volcanic ash was dated using isotopic dating methods and fossils were found in a sedimentary rock beneath the volcanic rock, it can be surmised that the fossils were older than the lava or ash. If the same species of fossils were found in another part of the world it would make sense that the rocks there were the same age as previous fossils. By cross checking with many other areas with other volcanic rocks, it can be found that all the rocks around the world containing those fossils were of a similar age.
Sedimentary rock is the most common type of rock that forms fossils because it is often laid down in layers that can preserve organic remains such as bones or shells. Other types of rocks like volcanic or metamorphic can also contain fossils under certain conditions, but sedimentary rocks are the most favorable for fossil preservation.
Sedimentary - but itdoes not necessarily contain fossils to be sedimentary.

They Often Contain fossils.
Metamorphic rocks do not typically contain fossils, as the intense heat and pressure involved in their formation often destroy any remnants of organic matter. Igneous rocks are formed from molten material and do not contain fossils. Sedimentary rocks, which form from the accumulation and compression of sediments, are the type of rock that commonly contain fossils.
No. Pumice is a volcanic rock. Volcanic rocks do not contain calcite.
Sedimentary rocks, such as limestone, sandstone, and shale, are the most common types of rocks that contain fossils. Fossils are formed when the remains of plants and animals are buried in sediment and eventually become preserved in rock over time. Igneous and metamorphic rocks typically do not contain fossils.
Quite often, fossils are contained within shale rock.
There are three basic types of rock; sedimentary, igneous and metamorphic. Igneous rocks are formed by volcanic action and don't contain fossils. Sedimentary rocks are formed, usually under water, by eroded material accumulating. Metamorphic rocks are formed when sedimentary rocks are changed by heating and/or pressure. From this, you can see that sedimentary rocks are the most likely to contain fossils, although metamorphic rocks also can contain fossils. Any sedimentary rock can contain fossils, but some make fossil hunting easier. Shales and mudstones are particularly good; chalk is pretty much entirely made of fossils - it's formed of skeletons of small organisms, but its difficult to see the individual fossils.
