春天来了，万物复苏，阳光明媚。一天，一位身着邮政绿衣的恐龙邮差来到自贡恐龙博物馆，他轻快地说：“你们有一封来自英国的信件！”
是一封来自英国中部地区康格尔顿的信件
小朋友年仅7岁，她在信中说：
亲爱的自贡恐龙博物馆，我叫莉莉•瓦茵。
我是英国人。
我住得老远了，来参观的话得乘坐飞机！
如果可以的话，能给我寄点资料过来吗？
1、吃肉的肉食动物都叫什么？
2、第二个时期叫什么？
3、为什么迅猛龙跑那么快？
4、你们在哪里发现骨头的？
5、第一个植食性恐龙生活的时间？地点？
谢谢您阅读我的来信。
希望尽快收到回信。
写信人：莉莉 瓦茵 7岁
看了这封萌萌的来信，博物馆叔叔阿姨们的心都融化了。立刻请专家针对小朋友的提问进行了认真回复，全文如下（中文紧随其后）：
Dear Lily Viner,
It’s such a pleasure to know of your interest in our museum. As for the interesting questions you asked, the answers are as follows.
1.The meat eaters of dinosaurs are called carnivores. And among the permanent display of the dinosaur kingdom in the exhibition hall of the museum, there are 4 different species showing for the visitors, you can find them in the pictures below. Their nature depend on their different species, some are like present wolves, some are like tigers or lions.
Gasosaurus constructus(the latter one)
Szechuanosaurus zigongensis(the latter one)
Yangchuanosaurus hepingensis(the bigger one)
Szechuanosaurus campi(the standing ones)
2. Dear child, I’m a little confused by this question. The history of the earth we are living on is very long, which is about 4.6 billion years. But dinosaurs'' is not so much long. They have dominated the earth for about 160 million years, almost the whole Mesozoic era, including Triassic period, Jurassic period and Cretaceous period, from 252 million to 66 million years ago. Zigong dinosaurs belong to the Jurassic period.
3. We all know raptors run very fast. By comparing proportion of their femurs and tibias to the same parts of modern antelopes’, the scientists found they are similar. You know antelopes run very fast too.
4. We found bones in Zigong city, Sichuan province,southwest China. The city covers an area of 4,373 square kilometers, in which there are about 200 localities bearing fossils, more than 40 dinosaur fossil sites among them.
Dashanpu dinosaur fossil site is one of them, which contains 3,000 square meters. Zigong Dinosaur Museum was built over it and officially opened to the public in the Spring Festival of 1987. The Spring Festival is the most important traditional festival for Chinese, and it is also an occasion for family reunion which is a little similar to your Christmas Day. Zigong Dinosaur Museum, 9 km northeast of the downtown of Zigong, is the first professional dinosaur museum in China and one of the three largest dinosaur museums with burial site in the world. Covering an area of 70,000 square meters, Zigong Dinosaur Museum has a collection of fossil specimens almost including all the known dinosaur species in the Jurassic of 205-135 million years ago. It was regarded as “the best dinosaur museum in the world” by National Geographic.

5.Riojasaurus may be the first plants eater. However, it was a so early dinosaur found in the late Triassic layer of which the exact year is still uncertain. It lived in where is Argentina now.
That’s all my answers for your questions, dear Lily. Hope it will meet your satisfaction. More information you can get at the website of Zigong Dinosaur Museum, http://www.zdm.cn, and you can also contact me at zgklbwg@163.com by email to get faster answer.
I’m looking forward to meeting you in the future, keep in touch.
Please pass my warm regards to your family.
Best wishes！
Yours sincerely,
Zigong Dinosaur Museum
回信中文翻译：
亲爱的莉莉 瓦茵：
知道你对我们博物馆这么感兴趣，非常高兴。你的问题很有趣，我们的专家经过研究，给出了答案。
1、吃肉的恐龙都叫做肉食龙。我们博物馆“恐龙世界”展厅里向游客们展示了4种肉食龙：建设气龙、自贡四川龙、和平永川龙和甘氏四川龙。它们的习性有的与今天的狼相似，有的又像老虎或狮子。
2、亲爱的孩子，原谅我！我被这个问题搞得有些糊涂了。我们赖以生存的地球，它的历史很长很长，有46亿年。不过，恐龙的历史要短得多。它们统治地球大概有1亿6千万年，历经了整个中生代(距今约2.52亿年至0.66亿年前)。这个时期包括三叠纪、侏罗纪和白垩纪。自贡恐龙都是侏罗纪时代的。
3、我们都知道迅猛龙跑得非常快。通过与现在的羚羊作对比，科学家发现它们股骨和胫骨比例极其相似。你知道，羚羊也跑得非常快。
4、我们在位于中国西南部的四川省自贡市发现了这些化石。自贡市有4373平方公里，有化石点200多处，其中，约有140多个是恐龙化石点。自贡恐龙博物馆就是在“大山铺恐龙化石群遗址”上修建起来的，在1987年春节开放。春节是中国人是最重要的传统节日，也是家人团聚的日子，这一点与你们的圣诞节有些相似。自贡恐龙博物馆是中国第一座专业恐龙博物馆，世界三大拥有恐龙遗址的博物馆之一，博物馆收藏有侏罗纪（2.05亿年至1.35亿年前）所有已知恐龙。美国《国家地理》称自贡恐龙博物馆是“世界上最好的恐龙博物馆”。
5、里奥哈龙或许是世界上最早的植食性恐龙。它被发现的地层属三叠纪晚期，具体年代至今还未探明。它曾经生活过的地方现在叫做阿根廷。
亲爱的莉莉，以上就是我的回答，希望你能满意。更多资料，可以登录我馆的官方网站http://www.zdm.cn获取。如果发电子邮件至zgklbwg@163.com邮箱，可得到更快的回复。
期待与你在不久的将来见面，保持联系。
向你的家人问好。
