Hello, yes for sure there is two rotworms corpses that won´t decay located on a Venore Southern Swamp. To find them exit venore south gate and keep going south. After reaching the swamp troll spawn go to -1 and follow the west path, next go south and west to room with the bodies as it is shown on the screen.

Rotworms corpses
They are non-packable.
Sadly I could not locate the dwarf corpses yet, but if I will find it I will let you know for sure.
