- •
Strontium isotopes in most shark tooth enameloid show good numeric age correlation.
- •
Samples from non-porous marine strata produce better results than sandy strata.
- •
Strontium isotope ratios are similar between the different shark taxa analyzed.
- •
Some strontium ages compare well with the absolute age of a bentonite studied.
- •
This method may be useful for regional and global stratigraphic correlation.
