No, but it kills an awful lot of creatures if they stay in it long enough.So an antimagic field simply dissolves all matter in D&D world.

I ended my first big campaign* this way. A background plot element through its whole ten+ year run was that magic was unstable/chaotic and slowly - later quickly - becoming more so. The solution in the end was to - through the PCs - make the world entirely non-magical, turning it into an Earth-like exoplanet and in the process killing off a stupendous number of fantastic and magic-based creatures who couldn't find a way off in time.
* - it had run its course in any case; none of us were too sorry to see it go.

A griffin is not a normal animal. It's a fantastic beast.I mean, this is a world where fantastic metals like mithral and adamantine would exist as trace minerals, whatever is in various plants and animals that cause them to be alchemical ingredients would be part of it too. And let's not forget otherwise normal animals like griffins.
Au contraire - I think it's what opens the door for the fantastic to not only exist, but thrive.Assuming magic is necessary for the fantastic is severely limiting to the fantastic.
