Megamirounga

Megamirounga was the biggest of all pinnipeds and was the buggest carnivorans that has ever lived, being almost as large as the extinct Andrewsarchus. It was native to much of Southern South America, Southern Africa, Southern Australia, and Antarctica, where they once lived in large colonies much like today's Southern elephant seals, their closest living relatives alive today. It did not have a short trunk of many other elephant seals, unlike the modern elephant seals. It most likely fed on the same type of food as today's fur seals due to the lack of evidence of the short trunk in Megamirounga. The reason for its extinction is unknown, but it most likely died out as the result of the Ice Age ending around 10,000 years ago, when the fishstock changed drastically, ending the existence of the Megamirounga.
