Not Yacht Rock at all, Was Not Was is a super weird/very experimental band from suburban Detroit. In the 80s, they mashed together a lot of genres, including funk, jazz, disco and pop, with poetic and political lyrics. They got back together in the mid-00s for a reunion of sorts. This song, inexplicably about life in prehistoric times (where the dinosaur is obviously the family pet), is from their 1988 album What Up, Dog?.
I have a lot of good memories of dancing to this song as a very small child, usually with the other small children of friends of my dad. Actually, if you ever find yourself searching for the perfect song to dance to in the company of small children, this is definitely it. I'm into everything about this jam, except those cavemen dudes in the background. Even though I know I did love them as a child, I kinda don't love them now. Otherwise, timeless.

It was a night like this, forty million years ago,
I lit a cigarette, picked up a monkey skull to go.
