Final answer:
During the Early and Middle Jurassic, parts of Pangaea were covered by dense jungles, supported by fossils and plant dominance of huge seed ferns and conifers.
Step-by-step explanation:
During the Early and Middle Jurassic, parts of Pangaea were covered by dense jungles. The climate during this period was warm and Earth's overall climate lacked ice, making it suitable for the growth of lush vegetation and a diverse range of plant and animal species. This is supported by the fact that huge seed ferns and conifers dominated the forests during this time. The separation of Pangaea into Laurasia and Gondwanaland began during the Triassic Period.
