racemization is defined as if we add cis and anti form it give rise to racemic mixture

Date objects in most programming languages typically have a limited range, often covering years from around 100 to 10,000 years. Beyond that, precision may decrease or errors may occur due to limitations in the data type used to store dates. For dates up to a million years, specialized libraries or custom solutions may be needed.

Scientists determine the actual age of trilobites and other fossils using a method called radiometric dating. This involves measuring the ratio of certain radioactive isotopes in the fossil and the surrounding rocks. By comparing this ratio to the known decay rate of the isotopes, scientists can calculate the age of the fossil. Other dating methods, such as relative dating based on the position of the fossil in the rock layers, can also be used to estimate the age of fossils.
