I went through the movie on my computer and saved a few images that should quell any Venom talk.
I was going to go to Paint and circle the skeleton, but thought it was pretty obvious. Eddie Brock is dead. No more Venom. It sucks, I know, but it's not my fault. As for the symbiote, unless a piece survive the bomb and found a host within about 2-3 hours, or the sample Conners has is in stasis of some sort, then Carnage can't be there without another meteor, as the symbiote cannot survive without a host for more than a few hours. Of course, movie studios do what they want anyway.
