Maybe I'm reading this incorrectly but it seems to me that
When combined with the "examples listed beneath it- that natural weapons' types are along the lines of Bite/claw or talon/gore etc.
Other than the fact that it is prefaced with "these are the most common" that the types are not S/P/B (like weapons) but rather more along the lines of bite or gore with the addition (when applicable) of the type of damage they do (e.g, S/P/B).
The wording is poor but the intent seems to be that natural weapons are classified in broader terms than are standard weapons.
Natural weapons have types just as other weapons do. The most common are summarized below.
