  • The daily growth layers arranged into seasonal and tidal patterns, present in calcified structures of many modern as well as fossil organisms, provide evidence on the length of lunar month and year in the geological past.The data presented are mainly from molluscan shells and indicate that the number of days per lunar month and per year has decreased significantly since Ordovician time. The change possibly has not taken place at a uniform rate.Banding and periodical patterns in stromatolites… CONTINUE READING
