Time range of radiocarbon dating
By definition, D* = N-1) (2) Now we can calculate the age if we know the number of daughter atoms produced by decay, D* and the number of parent atoms now present, N.
The only problem is that we only know the number of daughter atoms now present, and some of those may have been present prior to the start of our clock. The reason for this is that Rb has become distributed unequally through the Earth over time.
After the passage of two half-lives only 0.25 gram will remain, and after 3 half lives only 0.125 will remain etc.
It has become increasingly clear that these radiometric dating techniques agree with each other and as a whole, present a coherent picture in which the Earth was created a very long time ago.
Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.
Prior to 1905 the best and most accepted age of the Earth was that proposed by Lord Kelvin based on the amount of time necessary for the Earth to cool to its present temperature from a completely liquid state.
The finding radically suggests that early humans may have once walked the earth with the fearsome reptiles thousands of years ago.
The Triceratops brow horn was excavated in May 2012 and stored at the Glendive Dinosaur and Fossil Museum.
