Good question. However, I believe that Lepidodendron and other
arborescent lycopodophytes in the Carboniferous coal swamp forests
reached heights of 30 meters. That may be the result of competition
between plants for for sunlight, because all tetrapod denizens of those
forests were pretty much belly crawlers and could exert no pressure for
plants to grow that tall. Maybe sauropods did exert pressures to plants
to grow taller, but the Carboniferous forests show that such growth can
occur for other reasons. And why are Giant Sequoias so damn tall?
