Fossil 化石
Tow main types of fossils:
兩種主要的化石：
1. Body fossil
實體化石
Example: Dinosaur bones
例子：恐龍骨骸
2. Trace fossil
痕跡化石
Example: foot print
例子：脚印
Who study fossils?
誰研究化石？
Scientists who study fossils are called palaeontologists.
研究化石的科學家被稱爲古生物學家。
How Do Fossils Form?
化石是如何形成的？
The most common ways are formed when a plant or animal dies in a watery environment and is buried in mud and silt.
最常見的方式是當植物和動物在水中的環境死忙并被埋在泥土和淤沙中時形成的。
Soft tissues quickly decompose leaving the hard bones or shells behind.
軟組織迅速分解，留下堅硬的骨頭和殼。
The sediment slowly hardens into rock and preserves the shapes of the organisms.
沉澱物慢慢硬化成岩石並保留了生物體的形態。

What Are Fossils?
什麽是化石？
Fossils are the preserved remains, or traces, of animals or plants that were once living.

Why are fossils important?
爲什麽化石很重要？
Fossils give scientists evidence about organisms that previously lived on Earth.
化石為科學家提供了以前在地球生活過的生物證據。
We can use fossils to determine how organisms alive today evolved.
我們可以用化石來確定今天活著的生物是如何進化的。

Scientists who study fossils are called palaeontologists.

Palaeontologists compare fossils to find clues about early organisms and how they lived.
古生物學家通過比較化石尋找有關早期生物及其生活方式的綫索。
