How large could the giant sea turtle Archelon grow?
Correct!
Archelon was among the largest turtles that ever lived. Particularly large specimens reached about 4 to 4.6 meters in length, making it considerably larger than modern sea turtles.
This enormous sea turtle lived during the Late Cretaceous, about 80 million years ago. Its fossils come from the former Western Interior Seaway, which covered large parts of what is now North America.
