well, I do not know how to automatically list only "invalid" keys.
but you could do:
# backup you keyring, in case something goes wrong ;)
cp -a ~/.gnupg ~/.gnupg.bak
# list all main pub keys
gpg --list-public-keys | grep ^pub | sort > tmp.pubkey_list
#
# edit that file, _delete_ every line corresponding to a _valid_ key
#
# now, remove all keys still in that file in one run
cut -d " " -f 5- tmp.pubkey_list \
| xargs -l gpg --batch --yes --delete-key
# verify which keys are still there
gpg --list-public-keys
