Perfectly preserved dinosaur embryo最完整的恐龍胚胎

湯金霞

中國(guó)科學(xué)家在蛋化石中發(fā)現(xiàn)了保存完好的恐龍胚胎化石標(biāo)本，這個(gè)標(biāo)本叫作“英良貝貝”，是一只尚未破殼的竊蛋龍寶寶。

1?Scientists?in?China?have?discovered?a?rare?66?million?year?old?perfectly?preserved?fossil?of?a?baby?dinosaur?in?its?egg?showing?similarities?between?theropod?（獸腳類）?dinosaurs?and?the?birds?they?would?evolve?（進(jìn)化）?into.

2?The?embryo?（胚胎）?has?been?named?Baby?Yingliang?after?the?museum?in?southern?China?where?it?was?discovered.

3?According?to?an?ABC?News?report?published，?the?fossilised?bones?are?seen?curled?up?inside?its?6?inch?long?eggshell?and?look?almost?exactly?like?a?modern?bird?at?that?stage，?although?it?has?tiny?arms?and?claws?rather?than?wings.

4?Fion?Waisum?Ma，?a?paleontologist?at?the?University?of?Birmingham?and?one?of?the?authors?of?the?fossil?study?published?in?the?journal?iScience，?was?quoted?as?saying?that?the?head?in?the?embryo?has?a?striking?similarity?with?the?head?of?a?newly?hatched?bird，?especially?because?of?its?mouth，?which?was?a?feature?of?the?dinosaur?species，?called?oviraptorosaur.

5?Oviraptorosaurs?were?a?type?of?theropod?dinosaur?with?hollow?bones?and?three?toed?limbs.?It?was?very?close?to?the?dinosaurs?;that?evolved?into?modern?birds.

6?According?to?ABC?News，?embryonic?dinosaur?fossils，?which?the?paleontologists?have?found?at?only?about?half?a?dozen?sites，?are?extremely?valuable.

7?This?is?also?the?first?time?that?any?embryonic?dinosaur?fossils?have?shown?signs?of?a?distinctive?posture?known?as?“tucking”，?which?means?the?head?placed?under?the?right?arm，?though?some?dinosaur?embryos?have?shown?distinct?“egg?teeth”?that?they?may?have?used?to?break?out?of?their?shells，?said?John?Nudds，?a?paleontologist?at?the?University?of?Manchester，?who?wasn?t?involved?in?the?study.

8?The?researchers?said?the?embryo?s?shape?was?unique，?with?the?head?in?the?lower?part?of?the?body?and?legs?around?the?head—similar?to?a?modern?bird?embryo.?The?process?of?hatching，?which?earlier?studies?suggested?was?unique?to?birds，?may?have?evolved?from?dinosaurs，?they?said.

9?“A?fossil?embryo?is?a?rare?and?precious?resource?in?the?study?of?dinosaur?reproduction，?behavior?and?evolution，?as?well?as?in?paleoecology，”?said?Xing?Lida，?a?professor?at?China?University?of?Geosciences.

The?researchers?said?the?embryo?s?shape?was?unique，?with?the?head?in?the?lower?part?of?the?body?and?legs?around?the?head—similar?to?a?modern?bird?embryo.?研究團(tuán)隊(duì)說，這個(gè)胚胎的形狀很獨(dú)特，其頭部位于身體下方，腿圍繞著頭部，這種姿勢(shì)與現(xiàn)代鳥類的胚胎類似。

【點(diǎn)石成金】本句是一個(gè)主從復(fù)合句，句中the?embryo?s?shape?was?unique是賓語從句，作動(dòng)詞said的賓語;with?the?head?in?the?lower?part?of?the?body是with的復(fù)合結(jié)構(gòu)，作伴隨狀語。
