This makes the task of creationists building their model for the geological record much easier, since claims of U-Th-Pb radiometric “dating” having “proven” the claimed great antiquity of the earth, its strata and fossils can be justifiably ignored.

These shortcomings lead us to question the validity of the U-Pb dates published by Fassett et al.

and their conclusions regarding the existence of Paleocene dinosaurs.

At t=0, the equation for radiogenic Pb isotopes is indeterminate since it results in division by 0.

Secular scientists get around this problem by a clever application of l’Hôpital’s rule to estimate that the original ratio is (Pb)* = 0.04604.

This method reaches the pinnacle of radioisotope dating methods in terms of complication and convolution.
