Wikipedia reveals that this time frame encompassed land plants, including coal forming ones, and land animals including lizards during the upper Paleozoic Era.  Most fossil fuels formed during the warm and wet  Carboniferous Period of the upper Paleozoic Era

About halfway through the existence of Pangea, the Paleozoic Era became the lower Mesozoic Era, during which time conifers evolved on land and dinosaurs emerged.  The lower Mesozoic encompasses the time of the Triassic, just before the Jurassic, of Jurassic Park fame.
