It was thought to only lay eggs but experts have provided the first ever evidence that an ancient ancestor of the crocodile also had live births.
A remarkable 250 million-year-old fossil has been discovered which contains an embryo inside the mother.

鳄鱼一般被认为是只下蛋的，但专家提供了一个远古鳄鱼胎生的证据-----一个两亿五千万年前含有胚胎的母鳄鱼化石被发现。

The new fossil is from a distant ancestor of the crocodile that flourished in shallow seas of South China in the Middle Triassic.
Live birth is well known in mammals where the mother has a placenta to nourish the developing embryo.
It is also very common among lizards and snakes where the babies sometimes 'hatch' inside their mother and emerge without a shelled egg.

新化石来自一个生活在三迭纪华南浅海的远古鳄鱼。胎生在哺乳动物中是众所周知的，哺乳动物母亲具有滋养胚胎发育的胎盘。蜥蜴和蛇中也非常普遍有时婴儿在他们的母亲体内“孵化”而没有壳蛋的出现（蝮蛇等，也叫卵胎生）。

Until recently the third major group of living land vertebrates the crocodiles and birds only laid eggs. 

直到最近，作为第三种主要的陆生脊椎动物：鳄鱼和鸟类都被认为是只下蛋的。

Researchers from Hefei University of Technology in China discovered the new fossil of an unusual long-necked animal called Dinocephalosaurus - a creature that flourished in shallow seas of South China in the Middle Triassic. 

来自中国合肥工业大学的研究者们发现了新的化石——一种罕见的叫做“东方恐头龙”的长颈动物，这一生物在三叠纪中期时在华南浅海曾经大量繁衍。

An embryo was found inside the rib cage of the mother and facing forwards.

在恐头龙妈妈的胸腔里面发现了一个面朝前方的胚胎。

This suggests that the animal was not eaten - as swallowed animals generally face backwards because the predator swallows its prey head-first to help it go down its throat.

这表示这个动物可能不是被捕食的。通常被吃下的动物是面朝后的，因为食肉动物为了顺利吞咽那些被捕食的动物，经常先从脑袋吞起。

Not sensational reproduction at all. Monotremes are egg laying mammals. The Port Jackson shark lays eggs wheras most sharks are viviparous giving birth to fully functioning young with no external egg stage. Many reptiles are viviparous but some lizards such as Gecko's and some snakes such as Pythons are oviparous.

这没什么好大惊小怪的，卵生哺乳动物就是下蛋的哺乳动物。澳大利亚虎鲨下蛋，但是大多数的鲨鱼都是胎生的，生下来就生理功能齐全，没有产卵孵蛋阶段。一些爬行动物是胎生的，但是一些蜥蜴比如壁虎，还有树蟒是卵生的。

Revealed; 500 million yrs old fossil of pure B@ll S%it ! And to this day it hasn't evolved to anything except being used to push for the evolution theory.

大揭秘：《5亿年年份的纯狗屎化石！》
但是除了被用来证明进化论，直到今天它还没进化出啥东西来。

Why aare so many posting about evolution and religion? interesting story which doesn't mention either? evolution is a fact but why all the hostility to religious people who have said nothing here? Some need to grow up.

为啥有那么多关于进化论和宗教的言论？有趣的是，这则故事没有提到任何一种理论？进化论是事实，但是为什么所有的人都反宗教啊？他们宗教人士在这里可什么也没说。有些人需要成熟点了。

i) There's no evidence against evolution whatsoever. Not one piece. ii) Nor is there one single fact in all of science that supports creationism. iii) Creationism is scientifically impossible and rejected by any basic common-sense. iv) Creationism cannot not answer simple questions thrown up by simple biology and evolution. v) Creationists who argue against evolution invariably have not the faintest grasp of the subject. vi) Indoctrination and b r a i n w a s h i n g are genuine phenomena never recognised by the victims.

1、没有任何证据反对进化论，一条都没有。
2、也没有一件单独的科学事实支持神创论。
3、神创论在科学上来说是不可能的，而且跟任何基本的常识相悖.
4、神创论不能解释简单的关于生物和进化的问题。
5、神创论者在争论进化论时总是抓不住主题。
6、灌输和洗脑是永不会被受害者识破的真实现象。
