The careful study of geological maps helps to identify suitable areas for prospecting. Fossils occur in sedimentary rocks, which were deposited by wind or water. By contrast, igneous rocks, which formed from hot molten material that would burn any biological life, do not contain fossils.
How do paleontologist know where to dig?
In nearly all cases fossils are found by simply walking around looking at the rocks at one’s feet; paleontologists usually don’t know where to dig until they find bits of fossils eroding from the ground.
How are fossils excavated?
For paleontologists, excavating a fossil is a slow, careful process. … Working from the exposed bone surfaces to the unexposed surfaces, paleontologists slowly flake away the rock matrix that surrounds the bone. This may sound difficult, but there’s a plane of weakness between the bone and the rock.
Do paleontologists dig?
As we’ve discussed, the main component of a paleontologists job is their fieldwork. Paleontologists locate and excavate fossils and specimens out of the ground, using dig sites and technology to learn secrets about a world long gone.

When another substance fills in a mold and hardens it forms?
Fossils also form from molds and casts. If an organism completely dissolves in sedimentary rock, it can leave an impression of its exterior in the rock, called an external mold. If that mold gets filled with other minerals, it becomes a cast.
How long does it take to dig up a fossil?
2. Excavate. It can take a day or weeks to uncover a fossil, and sometimes multiple field seasons are required. It depends on how hard the rock is and how much overburden there is (rock or soil covering the fossil).
Where can Most of the fossils are found?
Most fossils are found in sedimentary rock. Sedimentary rock is formed by dirt (sand, silt, or clay) and debris that settles to the bottom of an ocean or lake and compresses for such a long time that it becomes hard as a rock. Limestone and sandstone are types of sedimentary rock that commonly have fossils.
What happens if I find a dinosaur bone?
If you find a dinosaur fossil on private land, it’s yours to do with as you please. In the United States, the fossilized remains of the mighty creatures that lived in eons past are subject to an age-old law—”finders keepers.” In America, if you find a dinosaur in your backyard, that is now your dinosaur.
Why are fossils buried so deep?
The remains of the animals buried within them do not decay, because they are buried so deeply that there is not enough oxygen to support living things that would eat them. As the sediment becomes rock, the bones (and sometimes traces of the skin) become mineralized.
