An Extinct Clam Fossil Is Indicating That About 70 Myrs Ago, The Earth’s Day Was Shorter–About 23.5 Hours And The Days In The Year Were Longer–About 372 Days. This Evidence Was Derived By Studying The Growth Patterns And Rhythms On The Clam’s Shell. The Earth/Moon Distance Relationship Is Said To Be Responsible For The Phenomenon.
How fast has the moon been moving away from Earth? A fossilized clamshell offers one step toward solving that puzzle.
