What are fossils for kids?

Fossils are the remains or traces of plants and animals that live a long time ago. Fossils help scientists understand what life was like millions of years ago. Some fossils provide evidence of living things that have gone extinct, which means they no longer found alive anywhere on earth today.

What is the most common fossil?

By far the most common fossil, based on the number of times it occurs in collections, is the snail Turritella, which is not only found almost everywhere since the Cretaceous, but is often quite abundant within each collection.

What is the oldest fossil?

cyanobacteria

The oldest known fossils, in fact, are cyanobacteria from Archaean rocks of western Australia, dated 3.5 billion years old. This may be somewhat surprising, since the oldest rocks are only a little older: 3.8 billion years old! Cyanobacteria are among the easiest microfossils to recognize.

How did dinosaurs turn into fossils?

The most common process of fossilization happens when an animal is buried by sediment, such as sand or silt, shortly after it dies. Its bones are protected from rotting by layers of sediment. As its body decomposes all the fleshy parts wear away and only the hard parts, like bones, teeth, and horns, are left behind.

How long did dinosaurs live on Earth?

Dinosaurs went extinct about 65 million years ago (at the end of the Cretaceous Period), after living on Earth for about 165 million years.

How much is a fossil worth?

Are rocks with fossils valuable? Except in very rare cases, rock, mineral and fossil specimens have little to no monetary value.

Do tar pits still exist?

What are the Tar Pits? The Tar Pits have fascinated scientists and visitors for over a century, and today, this area is the only actively excavated Ice Age fossil site found in an urban location in the world!

Where is the world's largest tar pit?

Trinidad

The largest tar pit in the world, La Brea Pitch Lake in Trinidad, has a fascinating history and awaits approval as a Unesco World Heritage Site – even if it resembles a somewhat neglected car park!

What is a mold fossil?

mold fossil (plural mold fossils) A fossil formed when sediment fills the inside or covers the outside of a dead organism and the organism's remains do not persist, leaving just the shape and texture of the rock to indicate the organic material that was there.

What is amber fossil?

amber, fossil tree resin that has achieved a stable state through loss of volatile constituents and chemical change after burial in the ground. Amber has been found throughout the world, but the largest and most significant deposits occur along the shores of the Baltic Sea in sands 40,000,000 to 60,000,000 years old.

What is a carbon fossil?

Carbon film fossils are carbonized two-dimensional remains of organisms that were exposed to great pressure over long periods of time. Carbon film fossils can often preserve information about the original organism's shape, features and evolutionary placement.

Are fossils rare?

Fossils are rare because most remains are consumed or destroyed soon after death. Even if bones are buried, they then must remain buried and be replaced with minerals. If an animal is frozen like the baby mammoth mentioned above, again the animal must remain undisturbed for many years before found.

Can humans become fossils?

On the other hand, it turns out humans are actually fairly well-suited to becoming fossils. “Mammals have a very good record, because teeth make fantastic fossils,” says Norell. “They're incredibly hard, incredibly resilient. Most of the fossils we find of mammals are teeth.” Great!

Can shells be fossils?

Seashell fossils are formed when a sea animal with a shell dies and their body and shell begin to decompose. Seashell fossils are more common than other fossils because the shell is hard and therefore more likely to be preserved, compared to organisms with only soft tissue.

Why are fossils buried so deep?

Why are fossils so deep in the ground? 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.
