Multiple Choice

Refer to the following information to answer the questions below.
Fossils of Lystrosaurus, a dicynodont therapsid, are most common in parts of modern-day South America, South Africa, Madagascar, India, South Australia, and Antarctica. It apparently lived in arid regions, and was mostly herbivorous. It originated during the mid-Permian period, survived the Permian extinction, and dwindled by the late Triassic, though there is evidence of a relict population in Australia during the Cretaceous. The dicynodonts had two large tusks, extending down from their upper jaws; the tusks were not used for food gathering, and in some species were limited to males. Food was gathered using an otherwise toothless beak. Judging from the fossil record, these pig-sized organisms were the most common mammal-like reptiles of the Permian.

• A)Its jaw would have been hinged the same way as the jaws of the early reptiles were hinged.
• B)It was a tetrapod.
• C)It had thin, moist skin without scales.
• D)Its dentition (tooth pattern)was typical of modern mammals.
• E)It would have had no temporal fenestra in its skull.
