Way back when I was a kid, the Sinclair Oil Company—long since absorbed into one of the modern oil giants—had a dinosaur as a sort of advertising mascot. This local oil delivery truck seems to have revived the notion. At risk of being pedantic, of course oil doesn't come from dinosaur carcasses. Big as they were, their biomass was inconsequential in the overall scheme of things. It's primitive plant forests and giant algal flats that compacted and eventually were transformed into hydorcarbons. Whatever.
