Cleveland-Lloyd Dinosaur Quarry 
What is a Junior Explorer? 

Junior Explorers 

BLM’s Junior Explorer program helps introduce young explorers like you to the lands and resources that the BLM 

manages. 

 This book contains information and activities about 

Cleveland-Lloyd Dinosaur Quarry. It is designed to help 

you discover and investigate the mystery of Cleveland-Lloyd. 

This site has been known about for over 80 years and we 

still don’t have a good explanation as to what happened here.

You can work through the activities on your own or invite a 

sibling, parent, or an adult you know to join you. When you 

complete the activities, check them with a Quarry staff person. Then say the Junior Explorer pledge on the certificate at 

the end of the book, sign the certificate, and you’re on your 

way to exploring and protecting America’s public lands. 

Have fun!
The Bureau of Land Management was formed in 1946 by combining the 

Grazing Service and the General Land Office. 

The BLM is responsible for carrying out a variety of programs for the management and conservation of resources on 245 million surface acres, as well 

as 700 million acres of subsurface mineral estate. The Bureau manages 

more public land than any other federal agency. 

Cleveland-Lloyd Dinosaur Quarry has the first visitors’ center managed by 

the BLM. The visitor’s center was dedicated in 1968 and renovated in 2006. 

The Cleveland-Lloyd Dinosaur Quarry was declared a National Natural 

Landmark in 1966. 

What is the Bureau of Land Management (BLM) ? 

To get started, ask a staff member to tell you the story of Cleveland-Lloyd. When you’re done, 

you’ll get a stamp to place in the 

box.

Welcome to Cleveland-Lloyd Dinosaur Quarry 

Look at the display in the visitors’ center to answer the following 

questions about the history of Cleveland-Lloyd. 

1. University of Utah __________ investigated the area in 1928 

and 1929 and unearthed about 500 bones. 

2. _____________________ grew up in the nearby town of 

Cleveland. 

3. _____________________,a lawyer in Philadelphia, donated 

$10,000 to fund the excavation of the quarry in 1941. 

4. What kinds of details are studied in the deposit? 

5. In _____, the University of Utah began excavation in cooperation with several universities and museums. 

6. Much of the work was done by ____________ under the direction of _______________. 

7. Paleontologists now understand that _________ alone don’t 

tell the whole story. 
How do you measure up? 

Take a look at the cast of the Camarasaur leg in the visitor’s center. The Camarasaurus is a type 

of dinosaur known as a sauropod. They ate plants and so they 

are called herbivores. They 

would have no trouble peeking 

into your second-floor window. 

Stand next to the leg and see 

how you measure up. Mark your 

height on the picture of the leg 

on this page. 
Where did all the bones go? 

The bones from Cleveland-Lloyd have been sent to museums all over the 

US and the world. Look at the world map in the visitors’ center to answer 

the questions below.

1. Where are you from? Are there any bones from Cleveland-Lloyd in your home 

state? 

 _______________________________________________________

2. List 3 countries other than the United States that have bones from Cleveland-Lloyd 

Dinosaur Quarry.

What Should You Bring? 

There are many great places to go hiking around Cleveland-Lloyd. The 

trails can be fun, but they can also be dangerous if you’re not prepared.

Look at the pictures below and circle the items that you should bring. Cross 

out the ones you should leave at home. 
 Fossilization 

The word paleontology means the study of ancient life. A paleontologist is someone 

who studies ancient life. Paleontologists try to piece together what an animal from 

long ago looked like, where they lived, and what they ate. They have to rely on fossils 

as their evidence. 

A fossil is the preserved remains 

or traces of an animal from the 

distant past. There are many different kinds of fossils. Fossilization will only take place under 

very special circumstances. Not 

every animal becomes a fossil. 

An animal dies and over time its 

bones are buried. 

Some remains can be petrified. 

This means that the remains were 

literally turned to stone. Microscopic spaces in the bones, teeth, or shells become filled 

with minerals. The bones at Cleveland-Lloyd have been petrified. 

Some fossils are called trace fossils because they give evidence that something alive 

had been there but no part of the animal is found. 

Look around the visitors’ center and you will find examples of both kinds 

of fossils. 
Carnivores and Herbivores 

There are two types of dinosaurs. The dinosaurs that eat plants are called herbivores

and those that eat meat are called carnivores. 

Complete the maze and help the allosaur find his meal.

Dinosaurs at CLDQ 

Look at the display in the visitors’ center for clues about each 

dinosaur. Draw a line from the dinosaur to its description. 

Allosaurus 

Stegosaurus 

Camarasaurus 

Ceratosaurus 

There were 46 of these found at Cleveland–

Lloyd. These animals were carnivores. A distinguishing characteristic is the presence of a 

small bony crest just above and forward of 

each eye. 

One of the few plated dinosaurs that were 

found in western North America. This dinosaur was an herbivore with large triangular 

plates arranged along its back. 

This long necked plant eater is one of the 

best studied of the sauropods. It was the 

first sauropod to be discovered with its skull. 

This carnivore is known for its small horns 

above the eyes and large horn on its nose. It 

is unlikely that the large horn was used for a 

weapon. 

Torvosaurus 

A powerfully built flesh eater with huge teeth 

and savage claws. This is one of the biggest 

late Jurassic carnivores. 
What is a Cultural or Natural Resource? 

Places like Cleveland–Lloyd exist to protect cultural and natural resources so they will 

be here for everyone to enjoy and learn about. 

A cultural resource is something that tells the story of the people that came before 

us. 

A natural resource can be plants, animals, water, or scenery. It is anything that is 

not made by humans. 

Look at the pictures below and read the description. Circle C if it is a cultural resource, or circle N if it is a natural resource. 

C N 

This arrowhead was made by 

American Indians 1,000 to 

1,500 years ago. They used flint 

from local sources as well as 

trading for it with other Indians. 

C N 

This is an allosaur’s 

crushed femur. Broken 

bones give scientists important clues about what 

happened to the animal 

after it died. 

C N 

This is a Pilling Figurine, 

named after Clarence Pilling, who discovered them 

in a cave in a side canyon 

of Range Creek back in 

1950. They are approximately 800-900 years old. 

C N 

This cabin, located in the Twin 

Peaks area, was part of a settlement from about 1900. The 

cabin is over 100 years old. 

C N 

This is a prickly pear cactus. In 

the summer, its red and yellow 

flowers can be seen in the area 

surrounding CLDQ. 
Everyone Needs a Home 

People and dinosaurs share some of the same needs. Every dinosaur needed a place to 

live. An animal’s (or dinosaur’s) home is called its habitat. 

An animal’s habitat includes food, shelter, and water.

Draw a picture of your habitat. Then draw a picture of your favorite dinosaur’s habitat. In both pictures, label food, shelter, and water.

Your Habitat 

Dinosaur’s Habitat
Excavation of a Dinosaur Bone

1. Remove overlying rock and expose the fossil. 

2. Apply special glues to consolidate the fossil and to prevent loss of 

smaller fragments. 

3. Surround the fossil with a protective “field jacket” made of burlap and plaster, and dig away the surrounding rock. 

4. Transport field jacket with the fossil to the paleontological laboratory. 

5. Prepare the fossil by removing surrounding rock, or “matrix,” and 

re-attaching small bone fragments with special glues. 

6. Curate in a museum where the fossil, associated clues, maps, 

notes, and important information may be studied and used to reassemble the puzzle.

Excavation techniques change with time. Paleontologists used to focus only on the 

bones. Surrounding sediments were ignored. 

Modern paleontologists, like modern forensic scientists, know that everything around 

a specimen is a potential clue. 

Look at the “story of a bone” panel in the visitors’ center. Write the number of each step on the picture it goes with on the next page.
