  • The study of fossil shells of Torreites sanchez, an extinct mollusk species of rudist clam that lived during the Cretaceous period, some 70 million years ago, Earth spun 372 times a year 70 million years ago compared to the current 365.This means the day was 23½ hours long compared to 24 hours.
  • The mollusk used to grow fast laying down daily growth rings. The rings allowed the scientists to determine the number of days in a year and more accurately calculate the length of a day 70 million years ago.
