My guess is that your AMG pan looks the way it does because it just happens to be from a later car. I'd be willing to bet that ALL of the later M104s look like that, even the non-AMG ones. That paper about the AMG C36 that someone linked (maybe it was you Jay) didn't say anything about a C36 AMG specific oil pan.

It's also my understanding that the early M104s had the exact same oil pan as the M103 did but the M104s had the added benefit of a genuine windage tray attached to the bottom of the engine.

This begs a bigger question though: Why are you inside your C36's engine? What happened? Please post a bunch of pictures of the insides of that puppy so we all can learn from it!
Regards, Eric
