When we histologically sectioned the specimen, we cut it up and we made a thin section, and we looked at it down the microscope.

我们对标本进行组织学切片，将其切开制成薄片，然后在显微镜下观察。

Although their claws are sharp, the hide of this Edmontosaurus is really tough and hard to penetrate, so they target a thinner section, and that is the neck.

尽管它们的爪子很锋利，但埃德蒙顿龙的厚皮又韧又硬，很难穿透，所以它们瞄准了皮肤较薄的部位就是它的脖子。
