Are dinosaure and vase irregulars? "Un" dinosaure and "le" vase?
Why do you mean by irregular? If it's because they end in -e, know that many masculine nouns do, just like many feminine nouns end in a consonant. Saying "feminine nouns generally end in -e" is merely a rough guideline and by no means a hard rule.
Yeah and as a helper, the words that end with -ge are usually masculine. I know you don't need this advice but it's for the people who visit this comment.
