Answer:
The correct answer is - The labyrinthodont.
Explanation:
Fossils of These duck billed dinosaur were found in the Antarctica in sands that were 66 to 67 million years old, however these are also found in north America and north Europe.
About 110 million years ago, labyrinthodonts, the dinosaur that are amphibians. These are the animals that were lived in the river valleys of the Gondwana and the rift valley that was located at that time between Australia and Antarctica.

Answer:
B) a nonsense mutation; this is because a nonsense mutation results in the change of a regular amino acid codon into a stop codon, which ceases translation. This fits with the problem's description of the protein that causes the symptoms as too short, as translation is the process by which proteins/polypeptides are created. A missense mutation would not be the answer because it still codes for an amino acid, which would not shorten the protein. A duplication of the gene would probably just lengthen the protein or not affect its length at all.
