Examine the shells ridges with a magnifying glass. According to Banque des Savoirs, a science and research site, these ridges can be an accurate indicator of age, especially in scallops, which produce about one ridge per day. Tabulate the number of ridges.
What was the first land animal on the Earth?
Discovered for the first time in 1899 on a Scottish isle, the fossil of the myriapod Kampecaris obanensis has now been radiometrically dated to roughly 425 million years ago. If the new date is correct, these ancient many-legged ones would be the oldest land animals to have lived out of water.

Why are there no shells on the beach?
As CO2 levels rise, the water becomes more acidic and the amount of carbonate (needed to make calcium carbonate — the compound that most shellfish and corals use to build their shells and skeletons) decreases. Eventually there is so little carbonate that shells or skeletons dont form properly or cant form at all.
