　　anatomy

　　解剖;分解

　　We are trying to understand the biology of sauropods, comparing their fossils to the anatomy of modern animals to get a better idea of how they lived.

　　get rid of

　　摆脱

　　Large animals can't easily get rid of excess body heat. But for an oceangoing whale, that's not a problem.

　　grind

　　磨碎

　　They swallow stones, stones that are used to help grind up the food before it's actually digested in the stomach.

　　ingest

　　咽下;吸收

　　It could be they were accidently ingested as the sauropods foraged for food, that they served no real purpose.

　　skull

　　头盖骨

　　Doctors have temporarily removed about half of her skull to ease pressure.

　　swallow

　　吞; 咽

　　Their skulls show they had no chewing muscles. Lots of modern animals, like birds and reptiles, also can't chew food. They need to swallow it whole.

　　smash up

　　砸坏;捣毁

　　Gastroliths make food easier to digest, essentially smashing food up, just as we do when we chew.

　　proportionally

　　按比例地

　　But we have been able to determine that the stones found with sauropods totaled much less proportionally, less than a tenth of one percent of their body weight.

　　speculate

　　推测;猜测

　　Other researchers speculate that sauropods ingested these stones as source of some the minerals they needed, such as calcium.

　　trace

　　痕迹

　　By fossils, we mean traces of prehistoric animals such as bones, which become mineralized, or impressions of bones or organs that are left in stone.
