Fossilized Jellyfish - Fossil Experiments For Kids

Fossils are often the hardest parts of plants and animals such as shells, bones, teeth, wood.
How can soft-bodied animals, trace fossils?

Materials needed to fossilized jellyfish

  • 3 courses
  • A little flour
  • A little gravel (fine pebbles)
  • Some sand (slightly wet)

Fossil Experiments For Kids Experience

  1. Put flour on a plate, on the other gravel (pebbles) and the last arena.
  2. Put your hand flat, tight, on each of the dishes.
  3. Look at the marks left when you remove your hand.

What do you notice?

The explanation
In flour, the track was very well marked
To the lines of the hand appear!. In the sand
contour is marked, but less detail
noticeable. In the gravel, the outline is just
marked. The more fine grains, more
accurate the reply you get.

Fossil Experiments For Kids The application
The same phenomenon observed in this experiment occurs with
fossilization. Depending on the size of sediment grains, minerals
you have (sand, gravel, ash …) the body has been buried
is more or less well preserved. Thus, a sediment of extreme fineness,
even a very soft, you can leave an imprint. In old rocks from 580 to 560
million years, Edicara (Australia) have discovered the remains of animals
Soft-bodied. The conditions have allowed exceptional fossilization
the conservation of organisms devoid of mineralized skeleton worms,
jellyfish and others who do not belong to any known group in the present.
