Apparent Loss of Angular Momentum in the Earth-Moon System

PANNELLA 1,2 and others 3,4 have presented palaeontological counts of the number of days per solar year ( N ) and per synodic month ( n ) during geologic time. This method is based on the cyclic growth increments of various fossils and has been confirmed in their modern counterparts 1,5 . The observ...

Zusammenfassung:PANNELLA 1,2 and others 3,4 have presented palaeontological counts of the number of days per solar year ( N ) and per synodic month ( n ) during geologic time. This method is based on the cyclic growth increments of various fossils and has been confirmed in their modern counterparts 1,5 . The observations extend back to 1.7 × 10 9 yr with some incomplete data to 2.8 × 10 9 yr.
