And it contains a lot of hard phytoliths, as a defence against hungry jaws. 青草含有許多堅硬的植物微粒，這些微粒可以保護自己不被饑餓的恐龍咬碎和消化掉。

But they also came across some phytoliths that could only have come from grass. 但是他們也碰到一些只可能來自于青草的植物微粒。

They then ground up the pieces of fossilized dung, known as coprolites, and looked for phytoliths, microscopic pieces of silica from plant cells. 他們將恐龍糞便化石（即糞化石）顆粒碾碎，尋找植物微粒，即植物細胞中的微小硅粒。

These bits of undigested plant matter, or phytoliths, come from a site containing bones of titanosaurs, long-necked plant eaters that lived near the end of the dinosaurs' reign. 這些未消化的小塊植物體（植物化石），是在泰坦巨龍化石附近出土的，泰坦巨龍是一種長頸草食恐龍，生活在恐龍王朝末期。

Here, we report on phytoliths extracted from six samples from the Shanwang Formation, providing new evidence of the vegetation that grew around the lake. 本文首次對山旺組樣品中的植硅體進行了研究，為山旺中新世植被的研究提供了新的證據(jù)。
