Apparent Loss of Angular Momentum in the Earth–Moon System

Abstract

PANNELLA1,2 and others3,4 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 counterparts1,5. The observations extend back to 1.7 × 109 yr with some incomplete data to 2.8 × 109 yr.
