Unfortunately, while the value of a rare stamp is really only what someone is willing to pay for it, the rarest natural history objects, such as fossils, are also the ones with the greatest scientific value. This fossil has scientific value to me, but not a commercial value because it is common.
Q. Will all the carbon-14 eventually disappear?
The half-life of carbon-14 is the amount of time it takes for one-half of the original amount to disappear by radioactive decay. After 50,000 years, a fossil won’t have any radiocarbon left in it. Carbon-14 will have all disappeared by radioactive decay.

Q. How can you tell how old a fossil is?
To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.
Q. Can I find a dinosaur bone in my backyard?
In the United States, the fossilized remains of the mighty creatures that lived in eons past are subject to an age-old law—”finders keepers.” In America, if you find a dinosaur in your backyard, that is now your dinosaur. Fossils found on private land… belong to the landowner.”
Q. What is the composition of most volcanic ash?
These types of magma have different melting points, viscosities, and typical volatile contents. The mineral composition of volcanic ash consists of about 45–75 wt% of silica [27]. In addition, silicate is the main component of most minerals like feldspar, olivine, pyroxene, hornblende, and biotite [29].
Q. How does volcanic ash affect weather?
Volcanic ash or dust released into the atmosphere during an eruption shade sunlight and cause temporary cooling. Larger particles of ash have little effect because they fall out of the air quickly. Small ash particles form a dark cloud in the troposphere that shades and cools the area directly below.
