Roman Cursive

This is kind of off topic to Latin that is why I put it in this forum. Does anyone know about the Ancient Roman Cursive Script? I tried my hand at doing it with with a dip pen by copying one of the Latin lessons out of the Cambridge Latin Course book lol, looks kind of cool and you get used to reading it even though it is confusing at first. The reason I ask is I was wondering did the Romans use punctuation like full stops and so on? I know they very rarely put spaces between words which is the case for many early manuscripts.
