An extinct giant sea turtle from the Cretaceous period, one of the largest sea turtles ever to exist.
From Greek 'arche-' (original, primitive) combined with 'chelone' (turtle), becoming 'archelon.' Named as the 'original' or 'first' turtle in evolutionary understanding.
Archelon was a massive sea turtle that cruised Earth's oceans 80 million years ago—some grew as big as a car! Its name literally means 'original turtle,' but it was actually highly specialized.
