known to be, be assumed to be.

bones now known to be those of large prehistoric animals作同位成分

补充说明句子主语any large bones.

句子有两个谓语部分，第一个是were assumed to be，搭配主语即，bones

were assumed to be the remains of giants.

句子主语any large bones ... known to be those of (bones 不是animal 所以加those)...assumed to be (bones就是remains 所以不加those).
这样看来，
D/E末尾有those of 排除
A前半句没有those 排除
B选项assume as 错 排除
选C
