Summary
The slow decay of naturally occurring radioactive elements in the earth's crust has ticked off the seconds with unalterable precision since the earth was born. Thus by measuring the amount of the elements' decay we can determine the age of the material of which they are a part. The first purpose of the work in this thesis was to seek additional criteria which may be applied to fossil marine mollusks as tests of closed system conditions. The second purpose was to apply these criteria to two series of well preserved fossil marine mollusks.
