A Dinosaur That Probably Ate Fruit
1Scientists have found a dinosaur that probably ate fruit. Its name, Infernogallus, means hell chicken. The name comes from Hell Creek, the area in the United States where its bones were found.
2The dinosaur was about the size of a turkey. It weighed about 12 kilograms and had no teeth. Its skull was small enough to fit in your hand.
3Scientists used CT scans to study the skull. They found that its jaw moved forward and backward, not up and down. Some parrots that eat fruit move their jaws in a similar way.
4The scientists think the dinosaur mashed soft fruits with a hard seed inside, like cherries and peaches. They say it may be the first dinosaur scientists know of that was built for eating fruit. The study was published in the journal Nature Communications.

全文訳
1科学者たちが、たぶん果物を食べていた恐竜を見つけました。その名前「インフェルノガルス」は、「地獄のニワトリ」という意味です。この名前は、骨が見つかったアメリカの「ヘルクリーク」という地域から来ています。
2この恐竜は、七面鳥くらいの大きさでした。重さは約12キロで、歯はありませんでした。頭の骨は、手のひらにのるくらい小さいものでした。
3科学者たちは、CTスキャンを使って頭の骨を調べました。すると、あごが上下ではなく、前後に動いていたことがわかりました。果物を食べるオウムの中には、同じようにあごを動かすものがいます。
4科学者たちは、この恐竜が、サクランボやモモのように中にかたい種があるやわらかい実をつぶして食べていたと考えています。果物を食べるためのつくりをした恐竜としては、知られている中で初めてかもしれないそうです。研究は「ネイチャー・コミュニケーションズ」という科学雑誌にのりました。
文法ポイント:形容詞 + enough to ~(~できるほど…)
〈形容詞 + enough to + 動詞の原形〉で「~できるほど…だ」。本文の Its skull was small enough to fit in your hand.(頭の骨は手にのるほど小さかった)がその例。enough は形容詞のあとに置く。
