这些科学家正小心翼翼地把恐龙化石从地下挖出来。 他们会把化石包好，保护它们不受损坏。 之后他们会把化石送到博物馆。

At the museum, scientists will study the fossils. They try to fit bone fossils together to make a skeleton. Some pieces of the skeleton might be missing. Scientists use what they know about other animals to make pieces fit.

在博物馆里，科学家们会研究这些化石。 他们试着把骨骼化石拼接起来，拼成一副骨架。 骨架的有些部分可能已经找不到了。 科学家会利用他们对其他动物的了解来补全缺失的部分。

Learning from fossils. Scientists study other animals to learn about dinosaurs. Dinosaur bones may be bigger, but many are shaped the same.
