Ankylosaurus' specialized armor is designed to be strong and lightweight.

Skeletal plates embedded in the skin are aligned in regular rows down the neck, back, and hips.
嵌在皮肤下的骨骼板沿着颈部，背部，臀部一路排列地整整齐齐。

Spaces between the plates allow this balky creature to move freely.
骨板之间的都留有空隙，可以让这个迟缓的生物行动自如。
While similar to scales found on today's crocodiles or alligators,
尽管在现在的鳄鱼身上也与之构造相类似的鳞片，
the way these plates are constructed makes them much tougher.

They're made of crisscrossing layers of minerals and collagen
它们是由矿物质和胶原蛋白构成的交错网层，
fibers made of protein that strengthen bone the way steel rods reinforce concrete.
而胶原蛋白是一种蛋白质纤维，它能像钢筋强化混凝土一样强化骨质。
It's a design used today in bulletproof jackets.
这也是当今防弹衣的设计原理。
