Why do bones turn blue?

The composition of the bones was altered over the thousands of years they spent in the cave. Specifically, the colour change appears to have been brought about by heating following the incorporation of the metal manganese (oxidizing it to the Mn⁵⁺ valence state, which forms blue-coloured salts).

Why would a bone be yellow?

Do bones decompose in a coffin?

By 50 years in, your tissues will have liquefied and disappeared, leaving behind mummified skin and tendons. Eventually these too will disintegrate, and after 80 years in that coffin, your bones will crack as the soft collagen inside them deteriorates, leaving nothing but the brittle mineral frame behind.

Why did dinosaur bones not decompose?

Its bones are protected from rotting by layers of sediment. As its body decomposes all the fleshy parts wear away and only the hard parts, like bones, teeth, and horns, are left behind. Over millions of years, water in the nearby rocks surrounds these hard parts, and minerals in the water replace them, bit by bit.
