Try washing your turtle's shell gently with a wet paper towel and see if some of the dark stuff comes off.
Usually wide seams are an indicator that a turtle is growing rapidly. For turtles, that's not necessarily a good thing - it's often a symptom of overfeeding.
Double check the amount your turtle is eating, and also whether the diet is balanced. Too much protein in particular will cause rapid growth in a turtle, which can lead to pyramiding and stress on the organs and a shortened life span. It's hard to resist a turtle begging for food - but we have to do what's best for them.
