Found this in Punta Cana ~3 months ago. What is this fossil and how old is it?

Likely a modern scleractinian coral.

Isn't this an imprint of a coral which may let one consider the possibility of a fossil?

It is an imprint, and so it is a fossil.  It does look like a scleracyinian coral.

Where about in Punta Cana was this found? I've done archaeological fieldwork in the area, but did a bit of palaeontological exploration in my free time and know that there are fossiliferous limestones in the general area. Not that I nitrogen to know their age... The beach-sands around the resorts, on the other hand, have been imported - I forget from where, if ever I know - and would thus be harder to date
