233640
Most trace fossils can be placed into three general categories: tracks and trails, burrows and borings, and gastroliths and coprolites. Each of these types of trace fossils helps decipher the activities of past life.

It is not the dinosaur bones themselves that paleontologists find, but their stony replicas. Fossil bones are created by the slow replacement of bone molecules with the molecules of minerals in ground water. ... Except for fossilized footprints, skeletal remains are the most common fossils.

Usually a dig isn't just spent getting the dinosaurs out of the ground. Scientists will also take the time to study the rocks and excavate other fossils they find along the way. Palaeontologists may use other techniques, too, such as screen washing.

There are 6 types of fossils. They are body, trace, cast and mold, living, s carbon film, and petrified wood. All of them have a way of bringing us back to the past and helping scientists gain more knowledge.

Fossil invertebrate animals (animals without backbones) are a wondrously diverse group with a fossil record spanning over 600 million years. Their abundance, diversity, and wide range of adaptations make them an ideal resource for scientists to use in understanding how our planet has changed over time.

A fossil is any remains of ancient life. Fossils can be body fossils, which are remains of the organism itself or trace fossils, such as burrows, tracks, or other evidence of activity. ... Index fossils are fossils that are widespread but only existed for a short period of time.

Researchers have uncovered dinosaur skin traces inside a set of one-inch-long footprints near Jinju—a city in South Korea. Finding well-preserved dinosaur soft tissue, such as skin and bones, is a rare occurrence. In fact, far less than one percent of dinosaur tracks contain any kind of skin traces.

Fossils provide the direct evidences of organic evolution. Fossils may be entire organisms buried in sediment or snow, small part of ancient organisms or impression of extinct organisms, ancient leaf or stem.

Fossils are the preserved remains or traces of animals, plants, and other organisms from the past. Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today.
