All of them, in fact. There are no bits of flesh still present in a millions-of-years-old fossil; it's all mineralized.
There are a variety of types of fossils. These include cast fossils, mold fossils, petrified wood, as well as fossil fuels.
Alberta, specifically the region around Drumheller, is known for having the most dinosaur fossils in Canada. The area is home to the Royal Tyrrell Museum, which showcases a wide variety of dinosaur specimens.
Like most fossils, dinosaur fossils have been mostly replaced with minerals and are not made of the original material. However, many contain trace amounts of original material. Some even contain proteins from the dinosaur.
Most often it is a paleontologist who finds dinosaur fossils. However, anyone can find one.
Most dinosaur fossils have been found in Europe and North America
molds and casts, trace fossils, petrified wood, and carbon filmThe four types of fossils are mold fossils, cast fossils, true-form fossils, and trace fossils. Mold fossils are impressions from when the plant or animal first decomposed. Cast fossils are plant or animal remains. True-form fossils are remaining body parts from an animal. Trace fossils are marks that have been left by animal, such as footprints.
Probably billions, most of which haven't even been discovered yet.
The best place to find dinosaur fossils in the world is in the United States. Another place to find dinosaur fossils is in Alberta, Canada. The best place to look for fossils is somewhere where there aren't many plants/trees, like a desert.
When most people think of fossils they think of dinosaur skeletons and large bones, but there are many different types of fossils to be found. Palaeontologists, people who study fossils, divide them into two major types - body fossils and trace fossils. Body fossils show us what a plant or animal looked like. The first type, body fossils, are the fossilised remains of an animal or plant, like bones, shells and leaves. These can be mould and cast fossils, like most of the fossilised dinosaur skeletons and big bones we see, replacement fossils, like petrified wood, or whole body fossils - mammoths caught in ice, or insects trapped in amber. Petrified wood, frozen mammoths, and insects in amber are all body fossils. The second type of fossil records the activity of an animal. Known as trace fossils, these include footprints, trackways, and coprolites (fossil poo!). Footprints and coprolite are trace fossils - they show us how an animal lived.
Many of the world's most iconic dinosaurs were first discovered in Montana. Some of Montana's dinosaurs include:TyrannosaurusTriceratopsDeinonychusMaiasauraHypacrosaurusAnkylosaurusDaspletosaurusTorosaurusAllosaurusApatosaurusZephyrosaurusMontanaceratopsAvaceratopsTroodonTenontosaurusSaurornitholestesStegosaurusEiniosaurusAchelousaurusAlbertosaurusEdmontosaurusCorythosaurus
Fossils exist of nearly all formerly living organisms, with some exceptions, from single celled bacteria to the largest dinosaur. Marine organisms comprise the bulk of fossils that are easily available today.
The fossil remains of dinosaur bones come in a different forms. Most have been petrified with calcium, yielding a stony texture and appearance. Agatized bones were petrified with silica or quartz, which gives the bones a glassy and colorful look.
