More Dinosaurs than Isla Nublar (okay, not really, PEACH)

Homebrew- from back on page 3:

Rancid Smell [Monstrous]
Some creatures wallow in their own feces, lessening their appeal to predators.
Prerequisites: Animal Vermin or Magical Beast subtype, Large Size or Larger
Benefits: Foes that come within 30 ft. of the creature must make a Fortitude save (DC 10 + 1/2 HD + Con modifier), or be sickened for a number of rounds equaling 1/2 the creature's HD (minimum 1). Creatures who make the save are immune to the stench for 24 hours.

Overpowering Stench [Monstrous]
Some creatures have even more disgusting smells than others of their kind.
Prerequisites: Rancid Smell or natural Stench ability.
Benefits: Whenever the creature's stench-based ability comes into play, all creatures within the designated radius must make a Fortitude save (DC 10 + 1/2 HD + Con modifier), or be nauseated for a number of rounds equaling 1/4 the creature's HD (minimum 1). If the stench ability lasts longer than the amount given, anyone who failed the saves act sickened for the remaining rounds.
