Oil leak, Rear main seal? Turbo? Oil Pan??

Whats up guys im new to the site just bought my LLY about 6 months ago, used the site quite a bit researching about duramax's before i bought mine.. love the truck, but i was changing the oil this past weekend and noticed a leak on the oil pan.. It drips off right below the drain bolt, but i noticed some on the tranny as well.. I tried to see if it was coming from above but it seems to be dry.. Is it possible it is just the drain plug and the wind is blowing it onto the tranny?? Let me know what you guys think or if there is something else i should look for, here are a few pics (after i wiped it of course so you wont see oil just residue).. thanks in advance guys
