Meet Dino Sue

It is May 17, 2000

The doors of the Field

Museum in Chicago fly

open Visitors crowd into

a large room They are

there to see something

big It is a dinosaur She

is 13 feet high and 42 feet

long Her name is Sue

Where did she come

from? How did she get

there? Who is Sue?

This is what visitors see when they first visit Dino Sue at the Field Museum in Chicago.

How Was Sue Discovered?

In the summer of 1990 Sue

Hendrickson was hunting fossils in South Dakota A surprise was waiting for her One morning she climbed a cliff to get a better look at some huge bones she had spotted She had found the remains

of a huge Tyrannosaurus rex, also called

a T rex

Sue Hendrickson was amazed to find a T rex.

The bones had been buried deep

under rock and dirt Over millions of

years the rock had worn away

How Did Sue Become a Fossil?

She died …

Her bones were

covered with sand

and mud…

The bones hardened

into rock They were

preserved Pressure

turned them into

fossils.

Hard Work

Uncovering the bones was hard work A team of workers gathered at the location They used small tools and worked slowly

It took them five days just to remove the

30 feet of rock that covered the bones The bones were old and weak

Workers had to be careful As each

bone was found, it was cleaned Then

it was labeled and packed Workers

found almost every bone in the

dinosaur’s body She was named Sue,

after Sue Hendrickson

Workers cut the fossils out of rock.

Workers spent 25,000 hours working

on Sue’s skeleton.

Boxes of Bones

The Field Museum in Chicago bought Sue In 2000 more than 250 boxes of bones arrived there

Museum workers spent two years putting Sue back together Each bone was cleaned again

When they were done, the museum

had a nearly complete skeleton of Sue The skull on Sue is made of plastic Her real skull is too heavy to be mounted

on the body Sue’s real skull is in a

smaller room in the museum In that

Sue’s skull makes her look like a fierce animal.

Sue Today

Putting Sue together in the museum took time and money Was it worth it? Yes! Sue provided evidence for scientists She helped them prove facts about life millions of years ago She showed them how a T rex moved and how long it

lived Sue may give clues that answer even more questions in the future
