Looking at the rules on harvesting trophies here:
https://aonprd.com/Rules.aspx?Name=Harvesting%20Trophies&Category=Troph ies%20and%20Treasures
It says:
In order to harvest and preserve a trophy from a kill, a character must attempt three checks: one to determine what parts of the creature are worth harvesting for a trophy, one to determine if she successfully harvests the trophy components without damaging or ruining them, and one to turn the components into a permanent trophy.
Identifying Trophies: To identify what portions of a creature have value as trophies, a character must succeed at a Knowledge check determined by the creature type, as normal. The DC for this check is equal to 15 + the creature’s CR. This examination takes 1 minute to perform.
Harvesting Trophy Components: Once a character identifies potential trophies, she must attempt a skill check to harvest the relevant components. This is typically either a Survival check (for external features, such as hide, horns, teeth, or the like) or a Heal check (for internal features, such as blood, internal organs, or sweat). The DC for this check is equal to 15 + the creature’s CR. Harvesting trophy components generally takes 10 minutes of work (at the GM’s discretion, this could be as much as 1 hour of work for creatures whose bodies are particularly difficult to work with).
My question is, can you have one character make the knowledge check and a different character do the heal/survival check? So the wizard identifies the good bits and the ranger actually harvests them, sort of thing?
I don't see why not. The rule keeps referring to 'a character' but I take that as an assumption rather than a requirement.
