What do you do if you find a dinosaur fossil?

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.

What are fossils who dig up them?

Paleontologists, who specialize in the field of geology, are the scientists that dig up dinosaur bones. Archaeologists study ancient people. Dinosaurs disappeared long before the first humans. Paleontologists tell us that dinosaurs went extinct about 65 million years ago.

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.

How are fossils collected?

Awls, rock hammers, chisels, and other tools are used to remove the rock covering the bones to see how much of the skeleton is present. Special glue is applied to the cracks and fractures to hold the fossil together. Next, a trench is dug around the bones so that they sit on a low pedestal.

Do Paleontologists make good money?

Paleontologists can make an average of $90,000 per year and must undergo extensive training in addition to completing a doctorate level of education. In this article, we explore the salaries of paleontologists, what these professionals do and the common skills needed to pursue a career as a paleontologist.

What rocks are dinosaurs found in?

The type of rocks in which dinosaur fossils (and almost all other fossils) are found is called sedimentary rock. Sedimentary rock generally occurs as flat layers called strata (single layers called stratum).

How do you tell a dinosaur bone from a rock?

A rock or concretion, like the one I showed to my professor, will be solid, and the inside of the rock will look like the outside. Fossil bone, on the other hand, will probably preserve the internal bone structure.

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.

Are dinosaurs still alive?

Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive. These, and all other non-avian dinosaurs became extinct at least 65 million years ago at the end of the Cretaceous Period.

Who is the most famous paleontologist in the world?

Jack Horner turned a childhood passion for fossil hunting into a career as a world-renowned paleontologist. During the mid-1970s, Horner and a colleague discovered in Montana the first dinosaur eggs and embryos ever found in the Western Hemisphere.
