[RPG] Will the Antimagic Field spell cause elementals not summoned by magic to dissipate?

antimagic-fielddnd-5emonstersspells

The antimagic field spell says that summoned creatures will temporally vanish until the creature is out of the antimagic field, but would an elemental native to the current plane vanish?

As an example, the UA Mystic can get psionic disciplines that create elementals.

No, they will stay

As you've said, antimagic field (PHB, 213) only affects creatures summoned or created by magic:

Creatures and Objects. A creature or object summoned or created by magic temporarily winks out of existence in the sphere. Such a creature instantly reappears once the space the creature occupied is no longer within the sphere.

Your run-of-the-mill elemental creature type is just a creature in the same way a humanoid, fiend, fey, construct are all just creatures. They would remain while inside an antimagic field.

But what if the creature type is created by magic?

As Gandalfmeansme points out, the physical form for elementals is created by the power of magic. What that means, we don't really know - but in general neither AMF or monster descriptions discuss how they'd interact with standard creatures types.

I've generally assumed creatures to be creatures unless brought in via other means like conjuring and that they just act as creatures. And while AMF is a high level spell, giving it the abilities of banishment seems a bridge too far for me on standard creature types.

Otherwise, we've got to create a system of what creature types are created by magic and how they'd interact. No such description is currently available, which suggests that AMF isn't supposed to interact directly with standard creature types.
