EXCAVATION

WARNING:

CHOKING HAZARD — S

Not for children under 3 yrs.

Excavating fun for

hildren ages 5 and up

Contains one of 12 diﬀerent

ollectible minerals and fossils

HERE’S HOW

Your excavation kit consists of a chisel

tool as well as a plaster block that

contains a mineral or fossil inside it.

You will also need a cup of water.

Before you begin excavating, set up

your work area: Spread a few layers

of newspaper on a tabletop. As pieces

of plaster might fall on the floor and

water might spill, make sure that it

won’t matter if the surrounding area

gets a little messy.

DEAR PARENTS,

Please provide your child with

assistance and support when

excavating the mineral or fossil.

Read the instructions together

before starting and follow them

carefully. Please ensure that

small children are not allowed to

handle any of the parts of this kit,

especially not the plaster pieces

that remain after the excavation.

WARNING! Not suitable for children under

 years. For use under adult supervision.

Read the instructions before use, follow

them and keep them for reference.

Do not inhale plaster dust or bring it into

contact with mouth or eyes. Wash hands

after use!

Keep the packaging and instructions as

they contain important information.

We reserve the right to make technical

changes.

Place the block in the cup

of water for a few minutes.

The plaster material to be

excavated will soften. The

longer it stays in the water,

the softer the material

becomes and the easier it is

to dig it out. At first, you can

only soften the outermost

layer. Once you’ve removed

that layer, you can soften

the inner layers and keep

working toward the center of

the block.

Dig your way to the mineral or fossil inside

the block by using the chisel to scrape away

at the plaster. As soon as you hit the stone,

start working very carefully and gradually

remove it from the final layers of plaster.

As a final step, you can completely remove

the mineral or fossil from the last bits of

plaster residue by holding it under running

water. Then rinse it well.

You can find out what the mineral or fossil

in your block is by comparing it with the

profiles on the back side. There are a total

of 12 different minerals and fossils. Collect

them all!

WARNING!

Not suitable for

children under 3

years. Choking

hazard — small

parts may be

swallowed or

inhaled.

SCLERACTINIA

Coral reefs are formed from the

limestone skeletons of marine

animals that died long ago. The star-

shaped structures of these primeval

underwater colonies have been well

preserved in the fossil record.

CRINOIDS

Sea creatures

like sea

lilies and

feather stars

are called

crinoids. Some

thick layers of

limestone from 200

million years ago consist almost

entirely of deposits of these animals.

Their stems and arms appear as ring-

shaped structures in the fossils.

PETRIFIED WOOD

Petrified wood forms when silicic acid

accumulates in a dead tree trunk or

branch and becomes

crystallized.

Petrified wood

structures ar

the type o

that the st

comes from

be identified.

PYRITE

This mineral is often called fool’s

gold. It consists of iron and sulfur

that forms cube-shaped or polygonal

crystals with a metallic sheen.

ROSE

QUARTZ

This quartz is a milky pink color

due to the inclusion of a reddish

substance. It is often used for jewelry

and art objects.

DIORITE

Diorite is a dark to black rock that

often has light-colored patterns in

it. It is formed by the slow cooling

of magma. Today it is often used in

construction and roads.

AMETHYST

Amethyst is a purple gemstone of the

quartz variety. Particularly beautiful

forms can be found inside the cavities

of round rock

formations

known as

geodes.

AVENTURINE

The green stone aventurine is also

a type of quartz. It is often used for

jewelry, while larger pieces of it can

be turned into tabletops,

boxes, or vases.

QUARTZ

Quartz is the crystalline form of silicon

dioxide, of which many types of rocks

and minerals are composed. In its pure

form without inclusions (a material

trapped inside a mineral during its

formation), quartz is transparent and

is called clear quartz or rock

crystal. If air or other

substances become

trapped inside

it, quartz can be

milky or colored.

RED JASPER

Jasper is also a type of quartz. There

are many different color variations,

often banded or flecked with

different colors.

The name is

Greek and

means

“speckled.”

PISOLITE

This limestone contains many

globular inclusions, called “pisoids”

(pea-like structures) that have

formed as layers

around a core,

which is

usually

a grain of

calcium

carbonate.

SEA LILY

Sea lilies — scientifically known as

crinoids — are echinoderms that are

related to sea urchins and starfish.

They attached themselves to the

seafloor with their long columnar

stalks which resembled

stacks of discs. There

are about 700

living specie

crinoids.
