答案：

C

解析：

【喵呜刷题小喵解析】：此题考查时态和believe的用法。当句子中出现“被认为”或“据说”这样的词时，通常用被动语态。而在被动语态中，通常用不定式来表达动作还未发生。在本题中，后半句提到“for we’ve had no track of them for ages”，说明这些动物已经很久没有踪迹了，因此可以推断出它们已经被认为是灭绝的。因此，正确答案是C选项，即“to have been extinct”，表示这些动物被认为已经灭绝。A选项“becoming extinct”表示正在灭绝，B选项“to become extinct”表示将来要灭绝，D选项“having been extinct”表示已经灭绝过，都不符合题意。
