How to become a Fossil?
120 million years ago,an iguanodon stood on a riverbank , chewing a leaf,It had been raining, and the bank was full of fresh new plants for his breakfast.
The rain also turned the hillside above into mud.Some of the mud began to slide.Faster and faster , down the hill , And right in the middle of breakfast, Wham!The poor iguanodon was rudely buried under a ton of mud.
Sadly , that was the end of the iguanodon, But it was the beginning of a brand new fossil.
Under the mud , bacteria and worms nibbled away all the soft bits of the iguannodon's body, They left a collection of bones and teeth under the muddy river.
1.2亿年前，一条禽龙站在河岸上，咬着一片树叶，天一直在下雨，岸边堆满了新鲜的植物作为他的早餐。
雨水也把山坡变成了泥浆。有些泥开始滑动。越来越快，下山，正吃早饭的时候，哇！可怜的禽龙被野蛮地埋在一吨烂泥里。
可悲的是，这是禽龙的末日，但它是一个全新化石的开始。
在泥浆中，细菌和蠕虫蚕食掉了禽龙身体上所有柔软的部分，它们在泥泞的河水下留下了一堆骨头和牙齿。
禽龙（学名：Iguanodon，意为“鬣蜥的牙齿”），属于蜥形纲鸟臀目鸟脚下目的禽龙类
