Original title: Chinese scientists have discovered the world's earliest herbaceous Angiosperms

Xinhua News Agency, Shenyang, March 7 (reporter Jiang Zhaochen)-164 million years ago, in the Jurassic strata in the plant fossil was discovered by scientists in China, the world's earliest known herbal found in Angiosperms, prompted people to re-examine the previous proposed Angiosperm evolution. This research results in cover articles published in China has recently published on the geology of the English version.

This was named Bo Jurassic fossil plants of the grass, is a Professor of paleontology Center of Bohai University Gang Han city found in daohugou in Inner Mongolia. Fossil plant seems a typical herb, although less than 4 cm tall, but roots, stems, leaves and fruits intact. "Show the fruit of this plant has matured, pointing to its property of Angiosperms, Bohai Sea grass is definitely a big Jurassic Angiosperm. "Researcher Gang Han said. This seemingly mundane conclusion taking into account the Jurassic and grasses found in the Middle Jurassic age becomes significant, scholars most people think because Western plant originates from the early Cretaceous in Angiosperms, grass and Bohai big Jurassic age of about 40 million years earlier than the early Cretaceous.

The famous botanist Li Bingtao "great discovery" to evaluate the bozhong Jurassic and grasses. He told reporters that the Angiosperm plant group is the most prosperous in the world, but the origins and early evolution has long been a great mystery. Previous think, the plant system in Woody Angiosperms are the most original, and Herb form is considered to be evolved from woody. Bohai Sea discovery of Jurassic and grasses, challenged this view, prompting people to re-examine common Angiosperm evolution in textbooks.

Partners of this research including Bohai University Liu Xueling, national Professor Liu Zhongjian Orchidaceous plant germplasm resources conservation Center, Chinese Academy of Sciences, Xishuangbanna Tropical Botanical Garden Dr Zhan Keping (France nationals), the CAs Nanjing Institute of geology and palaeontology Mao Limi, Wang Xin, Dr.

内蒙古发现世界上最早草本被子植物|内蒙古|草本被子植物_新闻资讯

　　原标题：我国科学家发现世界上最早的草本被子植物

　　新华社沈阳3月7日电 (记者姜兆臣) 1.64亿年前中侏罗世地层中的一种草本植物化石被我国科学家发现，这个目前世界上已知最早的草本被子植物的发现，促使人们重新审视前人提出的被子植物演化观。这一研究成果以封面文章发表在中国近日出版的《地质学报》英文版上。

　　这一被命名为渤大侏罗草的植物化石，是渤海大学古生物中心的韩刚教授在内蒙古宁城道虎沟发现的。植物化石看起来是一个典型的草本植物，虽然不到4厘米高，但根、茎、叶、果保存完整。“果实的出现表明该植物已经成熟，指向其被子植物属性，因此渤大侏罗草无疑是一个被子植物。”研究者韩刚说。这个看似平常的结论考虑到侏罗草出土在中侏罗世年代就变得意义非凡，因为目前欧美植物学界大部分人认为被子植物起源于早白垩世，而渤大侏罗草的年代比早白垩世提早了大约4000万年。

　　我国著名植物学家李秉滔用“了不起的发现”来评价渤大侏罗草。他告诉记者，被子植物是当今世界上最为繁盛的植物类群，但是其起源和早期演化长期以来一直是一个巨大的谜团。先前的植物系统学家认为被子植物中木本类是最为原始的，而草本形态被认为是从木本演化而来的。渤大侏罗草的发现，对这一观点提出了挑战，促使人们重新审视教科书中常见的被子植物演化观。

　　本次研究的合作者包括渤海大学刘雪凌，国家兰科植物种质资源保护中心刘仲键教授，中科院西双版纳热带植物园詹克平博士(法国籍)，中科院南京地质古生物研究所毛礼米、王鑫博士。
