On Safari at Anza-Borrego Desert State Park

Let’s follow the paleontology staff into the field…

Page 3: On Safari At Anza Borrego Desert State Park 1

Can you read this landscape? What can you see that gives you clues about the past geology of this area?

Page 4: On Safari At Anza Borrego Desert State Park 1

This scientist is using a compass to measure and record the angle of the sediment layers. Why?

Page 5: On Safari At Anza Borrego Desert State Park 1

“George teaches paleontology volunteers how to read the landscape.”

The precise location of each fossil is plotted on a map with GPS coordinates.

Page 7: On Safari At Anza Borrego Desert State Park 1

Can you locate the fossil bone fragments?

Page 8: On Safari At Anza Borrego Desert State Park 1

What does the fossil next to the hammer look like?

Page 9: On Safari At Anza Borrego Desert State Park 1

“ A BABY MAMMOTH SKULL!”Can you imagine how exciting it was to find this fossil?

Page 10: On Safari At Anza Borrego Desert State Park 1

Tools of a Paleontologist … trowels, brushes and dental picks help free the fossil from the rock.

Page 11: On Safari At Anza Borrego Desert State Park 1

This mudstone sediment is like cement! It took hundreds of hours of work to free this tusk from the place where this animal died .75 million years ago.

Page 12: On Safari At Anza Borrego Desert State Park 1

These bones were found near the site too… are they fossils?

How do we know? This would be a good question to ask the paleontologists.

Page 13: On Safari At Anza Borrego Desert State Park 1

Volunteers excavated two days a week for a year!

Page 14: On Safari At Anza Borrego Desert State Park 1

Can you see the root of the mammoth tusk? Imagine how much sediment will have to be Excavated to get the whole tusk out!

These fossils are very fragile.

A plaster cast will protect it for transport to the Lab

Student interns learn paleontology skills by working with the scientists in the field.

Page 16: On Safari At Anza Borrego Desert State Park 1

Most fossils are found far from any roads. Helicopters transfer the fossil tusk which weighs over 900 pounds because of all of the sediment still attached to it and the plaster cast surrounding it.

After a year of field excavation the fossil finally comes to the lab!

Page 18: On Safari At Anza Borrego Desert State Park 1

Lab work prepares the fossil specimens brought in from the field.You can find out more about this when you visit the lab.

Sandbags prop up fragile bones…

Page 20: On Safari At Anza Borrego Desert State Park 1

This volunteer spent a year conserving this fossil. Can you tell what it is?

Page 21: On Safari At Anza Borrego Desert State Park 1

Plaster is added for strength to replace pieces of bone that are missing.

Page 22: On Safari At Anza Borrego Desert State Park 1

The final step … CURATIONPaleontology staff will measure, photograph and numbereach specimen.

Page 23: On Safari At Anza Borrego Desert State Park 1

Detailed descriptions are written.

Page 24: On Safari At Anza Borrego Desert State Park 1

All of this information will go in a computer database that is used by paleontologists from all over the world.

Page 25: On Safari At Anza Borrego Desert State Park 1

George says, “ Paleontology is long hours of hard work!”

So why do people volunteer hundreds of hours to do this?

Page 26: On Safari At Anza Borrego Desert State Park 1

Because people are curious! They like being involved in helping to solve the mysteries of the badlands. They like putting together the puzzle that tells us the story of geologic and biologic changes on our planet.

How curious are you?
