Description: These fossil dolphin ear bones are heavily mineralized particles of the inner ear of Dolphins. This particular bone structure help the creature understand its orientation in space which enables it to sense gravity. They help with overall acceleration and deceleration, which is essential for proper balance and movement control in aquatic settings. Dolphin inner ear bones develop before the dolphins are born, and serve as a record of their entire life. Much like trees, Dolphin inner ear bones grow rings allowing age to be determined in a similar manner.
