On imaging, the mass is typically within the medullary cavity.

在，肿块通常位于腔内。

Bit by bit, it's all stored in her bones...specifically, medullary bone.

一点一点地，储存在头里，确切地说，在里。

Medullary bone is very special bone that's laid down only by an ovulating female.

是一种很独特的头，只有排卵期的雌性恐龙才有。

And like a Sauroposeidon, she'll store that calcium in her medullary bone.

就波塞冬龙一样，她会把钙储存在。

Medullary is a layer of bone which lines the interior of leg bones. It has no structural purpose.

是排列在腿的内部的一层头。它没有结构的用途。

Once stored in medullary bone, calcium and minerals can easily be broken down and sent to where it's needed.

一旦贮存在里钙和矿物很容易被分解，并且被输送到需要它的地方。

But since it could have been used to store medullary bone, we think that the repetisaurus this osteoderm came from was female.

但由于它可能被用来储存，我们认为这种皮来自的重复龙是雌性的。

This ends up causing new bone formation and the medullary cavites of the skull can expand outward, which causes enlarged cheeks and a " hair-on-end" appearance on skull x-ray.

这最终导致新形成，及颅腔可能向外扩展，在头颅X线表现为增大的脸颊以及“竖发征”。

Of course, the technique is not foolproof, as only female dinosaurs that are preparing to lay eggs, not juveniles or ones that just recently laid eggs, show medullary bone.

当然，这项技术并非万无一失，因为只有准备产卵的雌性恐龙，而不是幼龙或刚刚产卵的恐龙，才会显示出。

These flared ends, or epiphyses bookend the bone's shaft, or diaphysis, which — instead of having spongy bone in the center — surrounds a hollow medullary cavity that's full of that yellow marrow.

这些张开的末端，或称骺，包围着干，或干，干的中心不是海绵状，而是包围着一个充满黄色的空心腔。

Another part of this study also showed that the fossils of those brooding dinosaurs didn't have medullary bone, a type of bone tissue found in ovulating female birds that remains for a short time after they lay their eggs.

这项研究的另一部分还表明，那些育雏恐龙的化石没有，是一种在排卵的雌性鸟类中发现的组织，在它们产卵后会保留很短的时间。
