Answer:
The land where Mesosaurus fossils are found is dominated by grasslands and deserts, mostly situated on plateaus.
Step-by-step explanation:
The Mesosaurus is an extinct species of animal. It was a freshwater reptilian predator, similar in its characteristics to the modern-day crocodilians. The fossils of this ancient animal were among the first two that were used to support the theory of continental drift.
The fossils of Mesosaurus are found in central, south of western, and southwestern South America on one side, and south of central, and western half of southern Africa. The majority of the land in these places is dominated by plateaus. The climate is tropical dry and tropical dry and wet, thus the land is covered by deserts, steppes, and savannas.
