Looks a decent size. Hard to say what it is from the picture though. At that size the likely candidates are ground beetles, dung beetles & scarabs, longhorms, and some of the water beetles. That looks most like a dung beetle or scarab based on the thick legs.
thanks; you genius you ! Unlikely to be a dung as i saw one all black without the white mark; (which i assume to be the shell hardening proceess ?) and there was in no way a variety on animals in a large evergreen forest; fenced off up a hill; there where a few animal tracks but the majority of it was marsh moss bog; all beit dried due to the weather.
