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.
How long does it take dinosaur bones to decompose?
Bones are made of collagen and calcium phosphate, a combo that can last a very long time. Even in the worst conditions, in fact, bones take at least a few years to decompose. These conditions need to by warm and wet, drawing in bacteria that attack the collagen which breaks down the structure of the bone.
How deep are dinosaur bones buried?

How did Dinosaur Bones get buried?
Now suppose a dinosaur happened to die along a flooded river, collapsed into the water, and was washed downstream, where it quickly became buried in the river sediment. Over the ages, sediment piled on top of sediment, the pressure and heat turning it to sedimentary rock and the dinosaur’s bones becoming fossils.
Do human bones last forever?
Based on a wide range of extrinsic and intrinsic factors, bone can last for a few months to a few geologic eras, but the truth is that nothing lasts forever. Even fossils and mummies will eventually be pulverized or broken down over the course of millions (or billions) of years.
Can dinosaurs come back?

How do dinosaurs die?
The dinosaur-killing crash threw huge amounts of debris into the air and caused massive tidal waves to wash over parts of the American continents. There is also evidence of substantial fires from that point in history. For a long time it was thought that the non-bird dinosaurs died out 65 million years ago.
Are dinosaurs still alive in 2020?

Other than birds, however, there is no scientific evidence that any dinosaurs, such as Tyrannosaurus, Velociraptor, Apatosaurus, Stegosaurus, or Triceratops, are still alive.
Has there ever been a complete dinosaur skeleton found?
