There is a book by a vertebrate paleontologist on dating methods pertinent to vertebrate paleontologists. It says little about amino acid racemization, but simply dismisses it with the comment that it is of little value to vertebrate paleontology because of its heavy dependence on calibration by carbon 14.

Amino Acid Dating Introduction. Amino acid dating has an important attribute in common with Carbon 14 dating. While most other dating mechanisms date the rock surrounding fossils, both Amino Acid and Carbon 14 dating methods, date the actual fossil itself.
