In the early 1990s, scientist Sue Hendrickson discovered the world's largest Tyrannosaurus rex dinosaur skeleton. It was found in rock formations in the American state of South Dakota. The skeleton is known as Sue, in honor of Hendrickson.
Visitors to the Field Museum of Natural History in Chicago have been able to see Sue since 2000. However, for most of 2018, Sue was nowhere to be seen. Instead, experts spent 10 months working on and adding to the world-famous skeleton.
Jaap Hoogstraten is the Field Museum's director of exhibitions. He says museum workers have learned new things about the skeleton's shape since 2000.
Since 2000, we've made discoveries about the pose. We've added the gastralia, which are the belly ribs, which changes the outline of Sue quite a bit...
The ribs themselves are not a new discovery. They have existed since the fossil was recovered. But scientists only recently understood how they fit onto the skeleton.
That understanding greatly changes what is known about the Tyrannosaurus rex.
Hilary Hansen is the Field Museum project manager.
I didn't really realize that Sue weighed nine tons in real life. Really, adding this gastralia, these belly ribs, really changes the profile for Sue, and you can get a sense of how formidable and imposing it must have been to share an environment with this animal.
Hansen adds that Sue's newly opened exhibit changes our understanding of the animal itself. It also helps show visitors Sue's natural environment and place in history.
What we're trying to do is bring together everything about Sue that was all over the Field museum into one space so that our visitors can see this as a one-stop shop for all things Sue.
The Field Museum usually welcomes over one million visitors a year. But Hansen expects that number to increase because of the new Sue exhibit. She said the museum is expecting up to 10,000 visitors each day in the first weeks of 2019.

芝加哥菲尔德自然史博物馆的参观者们从2000年之后就可以观赏到这副骨架了 。不过，2018年的大部分时候，苏都不对外开放了 。取而代之的是：专家们花了10个月的时间潜心给这副世界上最出名的骨架添枝加叶 。
亚普·霍赫斯特拉滕是该博物馆的负责展览事务的主任 。他表示，博物馆的工作人员从2000年之后就对该骨架的形态有了新的认识 。
2000年以来，我们对它的姿势有了新的发现 。我们增加了胃骨片，也就是腹部的肋骨，从而少许改变了苏的轮廓 。
胃骨片本身并不是新发现 。胃骨片在该化石发现时就已经存在了 。但科学家是最近才得知胃骨片应该置于哪个部位的 。
我以前一直都没意识到苏的重量在现实生活中可以达到9吨 。增加了胃骨片之后，就改变了苏的形态，这样就能感受到跟雷克斯霸王龙共处一个空间时会有怎样的震撼感 。
我们正在努力将苏的所有骨骼拼凑在一起，放在同一个空间里 。这样，参观者们就能一站式地体验苏的样子 。
该博物馆每年的游客量一般有100多万 。但汉森认为，参观量会因苏的展出而增加 。她表示，该博物馆预计将在2019年初的数周内就达到1万的游客量 。
