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.
Do bones ever fully decompose?
In neutral-pH soil or sand, the skeleton can persist for hundreds of years before it finally disintegrates. Alternately, especially in very fine, dry, salty, anoxic, or mildly alkaline soils, bones may undergo fossilization, converting into minerals that may persist indefinitely.
Why do 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.

Which part of human body does not decompose?
The skeleton and teeth are much more robust. Although they undergo a number of subtle changes after death, they can remain intact for many years. During a person's lifetime, their skeleton is a dynamic living record that is altered both in its shape and chemistry by diet, the environment and daily activities.
Can human bones become fossils?
Bones, teeth, shells, and other hard body parts can be fairly easily preserved as fossils. However, they might become broken, worn, or even dissolved before they are buried by sediment.
Why are people buried 6 feet under?
Medical schools in the early 1800s bought cadavers for anatomical study and dissection, and some people supplied the demand by digging up fresh corpses. Gravesites reaching six feet helped prevent farmers from accidentally plowing up bodies.

Can human be petrified?
Petrified wood typifies this process, but all organisms, from bacteria to vertebrates, can become petrified (although harder, more durable matter such as bone, beaks, and shells survive the process better than softer remains such as muscle tissue, feathers, or skin).
Can bones turn stone?
Old bones, wood, and other harder organic matter form into stones when water carrying dissolved minerals seeps into small holes in the bones, wood, etc. Over time, the minerals can crystallize (solidify) and fill in the holes with rock material.
Why are you buried without shoes?
The family of the deceased also sometimes finds it wasteful to bury shoes, especially if someone else could wear them. Putting shoes on a dead person can also be very difficult. After death, the shape of the feet can become distorted. This is due to rigor mortis and other processes the body endures after death.
