Background: Animals such as cows and sheep lick mineral salts, particularly sodium, to replenish essential minerals. Sometimes, the dietary intake of animals lacks certain minerals, especially sodium. Mineral salts are typically rich in sodium; hence animals consume the necessary minerals by licking these salts. Mineral salts also contain other minerals like calcium, magnesium, and potassium, which help maintain the electrolyte balance in the bodies of cattle and sheep, promote the growth of livestock, and prevent mineral deficiency diseases such as pica, white muscle disease, and nutritional anemia.

Analysis: The main component of animal bones is hydroxyapatite, an inorganic salt with the chemical formula Ca5(PO4)3(OH). Hydroxyapatite is a calcium-phosphate compound known for its high hardness and stability, and it is the primary constituent of bones and teeth. The act of cattle and sheep licking salt blocks is symbolic, representing the unceasing transformation between the organic and inorganic worlds. Ancient flora and fauna, under geological processes, have become today's petroleum and coal, with minerals circulating within and among living organisms through chances and forces.

Operation:

1. Himalayan mineral salt blocks from Palestine are carved into the heads of animals such as cows, sheep, horses, and camels.

2. These salt-carved animal head sculptures are placed in grazing areas for cattle and sheep to lick. The licking causes the sculptures to blur and deform. Videos are taken of the animals licking the sculptures.

3. The deformed animal head salt sculptures are mounted on a wall, with the video displayed alongside.

4. A collection of cattle and sheep skull fossils is placed on the ground, with salt crystals growing between the gaps of the animal skulls.
