Answers will vary. Some possibilities are: How did behaviors like flight evolve? What did the land look like in the past? What kind of organisms existed in the past?
What questions can Fossils answer?
Fossils can tell us what the organisms liked or disliked. Fossils can tell what an organism looked like. Fossils can tell how organisms have changed over time. Fossils can tell us when the organism lived on Earth.
How are the fossils in question 8 formed?
Most fossils form when living things die and are buried by sediments. The sediments slowly harden into sedimentary rock and preserve the shapes of the organisms. … Other fossils form when the original remains of organisms are preserved in substances such as tar, amber, or ice.
How can fossils be destroyed?
Once buried, the fossil and surrounding rock might undergo extreme pressure and heat, and the fossils could melt. Once fossils are formed, they might be washed away by streams, moved by glaciers, carried by scavengers, or caught in rockslides. Weathering by wind, water, and sun can destroy a fossil by wearing it away.

How many types of fossils are there?
There are four main types of fossils, all formed in a different way, which are conducive to preserving different types of organisms. These are mold fossils, cast fossils, trace fossils and true form fossils.
Why do we study fossils?
Studying fossils helps them learn about when and how different species lived millions of years ago. Sometimes, fossils tell scientists how the Earth has changed.
What are the 3 conditions necessary to form fossils?
What conditions favor the formation of fossils? How might this cause the fossil record to be biased? The organism generally must have hard parts such as shell, bone, teeth, or wood tissue; the remains must escape destruction after death; and the remains must be buried rapidly to stop decomposition.
What can’t fossils tell us?
Fossils also show how animals changed over time and how they are related to one another. Fossils can’t tell us everything. While fossils reveal what ancient living things looked like, they keep us guessing about their color, sounds, and most of their behavior. Fossils are very rare.
What are the 5 stages of fossilisation?
Fossils form in five ways: preservation of original remains, permineralization, molds and casts, replacement, and compression.
Do fossils last forever?
The only exception is that of fossils, which after fossilization aren’t actually made of bone any longer. Some bones do last longer than others due to their environment and conditions, but even then, they are definitely not eternal. Fossilization is also not a process that happens simply or frequently.
How can we preserve fossils at home?
The most commonly used preservative is Elmer’s white glue. Do this by mixing 50% glue and 50% water and apply with a brush, only doing 1/2 of the fossil at a time.
What causes Fossilisation?
Fossils are formed in different ways, but most are formed when a plant or animal dies in a watery environment and is buried in mud and silt. Soft tissues quickly decompose leaving the hard bones or shells behind. Over time sediment builds over the top and hardens into rock.
What is the rarest fossil?
Baby bird fossil is ‘rarest of the rare’
- Scientists have unveiled one of the smallest bird fossils ever discovered.
- The chick lived 127 million years ago and belonged to a group of primitive birds that shared the planet with the dinosaurs.
What is an interesting fact about fossils?
Fossils represent the remains or traces of once-living organisms. Most fossils are the remains of extinct organisms — that is, they belong to plants or animals that are no longer living anywhere on Earth. The kinds of fossils found in rocks of different ages differ because life on Earth has changed through time.
What is the biggest fossil found?
A titanosaur is a type of sauropod which has been discovered in fossil beds around the world; the largest known individuals have been found in Patagonia. A type known as the Patagotitan weighed in at 77 tons, while the Argentinosaurus reached 110 tons and up to 40 meters (131 feet) in length.
