The first mark appears to be that of a butterfly and is found in the China-published “Collection of Classical Markings on Chinese Historical Porcelains” (Zhongguo lidai taoci kuanzhi dadian - 中国历代陶瓷款识大典). In my opinion, the second picture simply shows decoration in the cavetto, albeit might also be used as a base mark in other instances. I have a shallow bowl with similar decoration which has a square factory base mark consisting of a non-character cipher within a double square border of a type that was used in the late Ming and Kangxi period and also is pictured in the above-referenced book.
I can't say for sure whether these marks have been copied in later times but suspect they have, like just about everything else in porcelain.
