请教GMAT Prep 的两道语法题

(1) Taste buds are onio structures with between 50 and 100 taste cell, each of which has figurelike projections poking through the opening, called the taste pore, located at the top pf the taste bud.

请问蓝色部分做什么成分？原来对于这个语法还挺明白的，现在想不明白了，望赐教！

(2) A group of paleontologists recently announced that a site in Utah has yield fossils of some of the biggest armored dinosaurs ever found, fossils that are at least 25 millon years old than those of any similar dinosaur type previously found in North America.

GMAT　Ｐｒｅｐ　的题不让ｃｏｐｙ，ｐａｓｔｅ．　所以我只写出了正确选项。我认为ｃａｒｏｌｈｉｄｅ　是对的，后边的成分都是同位语。

谢谢！

可以的.

你按主"shift + print screen"键, 再打开"paint"windonws代的软件, 把它paste到里面去, save成文件.再传上来,就ok了.
