What is Dinosaur Bone and Gembone?

Here are some examples of petrified and agatized dinosaur bone. Once the bone has been agatized the organic parts of the bone are replaced with agate. Pretty cool results considering the process only took around 4 billion years.

Gembone is mineralized bone, often dinosaur bone, which has had the individual cells fossilized with precious minerals. It is one of three gemstones created from organisms (the others being Pearl and Ammolite). Many minerals can be found in Gembone including hematite, iron, pyrite, jasper, marcasite, agate, quartz or other crystals.

A fossil is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, hair, petrified wood, oil, coal and DNA remnants. The totality of fossils is known as the fossil record.

Paleontology is the study of fossils: their age, method of formation and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are from around 3.48 billion years old to 4.1 billion years old.The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the development of radiometric dating techniques in the early 20th century refined the dating process.
