D

Explanation: 

Detailed explanation-1: -The “dinosaur bones” that you see on display at the Museum aren’t really bones at all. Through the process of fossilization, ancient animal bones are turned into rock.

Detailed explanation-2: -Everyone learns in school that that dinosaur skeletons are bones turned to stone. Mineral-rich water percolated through the earthly remains of the ancient reptiles, transforming their osteology into something much harder over time.

Detailed explanation-3: -Dinosaur fossils come in two forms: body fossils and trace fossils. Body fossils are what we usually think of when we think of dinosaurs: bones, teeth, bony armor, rare soft tissue impressions, and so on.

Detailed explanation-4: -Museums are able to keep dinosaur bones together using a variety of different methods. The most common method is to use steel wires or rods to secure the bones in place. This method is typically used for smaller bones or for bones that are particularly fragile.

Detailed explanation-5: -A fossil is physical evidence of a prehistoric plant or animal. This may be their preserved remains or other traces, such as marks they made in the ground while they were alive. Fossilised remains-including fossil bones and teeth-are known as body fossils. Fossilised shells are also body fossils.
