Preservation of Amino Acids in Fossilized Dinosaur Eggshells Over Millions of Years

Fossilized dinosaur eggshells have been found to preserve ancient amino acids, the building blocks of proteins, over millions of years. This discovery provides a rare opportunity to study the biology of extinct organisms and sheds light on the molecular changes that occur in fossils over long periods of time. The amino acids detected in the eggshells were found to be ancient and original, possibly ranging from 66 million to 86 million years old, and their preservation is attributed to the calcite mineral within the eggshells. This research opens up new possibilities for studying ancient life and understanding their biology through the analysis of fossilized eggshells.
