Any loss of carbon-14 during fossilization or from exposure over the years would cause the sample to carbon date to an older age.

In permineralization the minerals fill in the empty spaces to form a fossil, but in petrification the minerals completely replace the original cellular material and the C.

Your T-shirt could soon contain the same carbon-14 as William the Conqueror’s robe from 1066 AD, scientists warn.

An article in Phys Org claims that radiocarbon dating is becoming more unreliable as carbon emissions increase.

Radiocarbon dating is not affected seriously yet, they claim, but will be by 2020 if emissions continue.

The stronger magnetic field would have shielded Earth from cosmic rays and solar flares resulting in less A fossilized ammonite and piece of wood in the Lower Cretaceous Budden Canyon Formation near Redding, California are assigned an age of 112 million to 120 million years old according to the geologic column.
