Four hundred million years ago, it was rare to find fossils in the second boy’s sophomore District i 3u8895

The big boy picked up the area four hundred million years ago fossils in Fuzhou rare Fuzhou evening news (micro-blog) September 17th news (reporter Chen Danwen photo) sophomore boys holiday home to celebrate the festival in the area on the grass to see a piece of abandoned marble, which was wrapped in more than 400 million years ago animal stone – armenoceras. The unexpected mid autumn gift delighted Lin Xianghong. Marble base pattern is very special, Lin Xianghong lived in Cangshan Fu Bay New Town, sophomore year this year, because of typhoon school holiday, 14, 14 points more than home. When he was carrying his luggage through a lawn downstairs, he was attracted by a round piece of marble. Xiao Lin is a fossil "fancier". He always likes to stare at the stone on the ground when he walks. He turns over the deserted marble with his habit, but he is surprised to find that there is a special pattern in the stone. Although the school is digital media professional, but he grew to love the collection of ancient biological data, also joined the fossil forum, organized fossils in the school, he recognized the special pattern is actually a fossil, and armenoceras. Kobayashi carefully observed, found in the middle of the stone nut nut, and home coat rack base exactly the same. To estimate who is a clothes is broken, the base was readily lost in the grass. Such a complete fossil is rare in Fuzhou!" Kobayashi took photos of the fossils and sent them to the familiar paleontology experts and fossil enthusiasts, and they all thought it was a fossil, and they all called it "Mid Autumn Festival" welfare". Yesterday, the reporter saw in Kobayashi home, this marble and ordinary stone is nothing like two, but there is a section of the white prints like wheel prints. Kobayashi told reporters, armenoceras is ancient invertebrates, living in more than 400 million years ago in the Ordovician, extinct. It is the modern Nautilus, one of the most common fossil is the Ordovician strata, common in various gray rock building stone. "After that the fossil from the Ordovician strata in the northern area of China, and the cross section of the well preserved, the cornerstone of tube and the baffle of biological structure to save the clear shell all calcitization, fossil specimens 23 cm long." Kobayashi believes that the origin of this fossil is more than 400 million years ago is an ocean. It is understood that the ordinary people dig fossil specimens such as trilobites, cephalopods and other fossils is not illegal, but if the unauthorized sale of fossil profits, is a violation of the relevant laws and regulations. Kobayashi said that this fossil can not be traded, has a high scientific value. "So big, I was first seen in Fuzhou, the general only about 5 cm exposed corner." Kobayashi said that he found fossils in many places in Fuzhou, for example, he had found fossils in the stones in the old campus of Fu Fu, West Lake Park and other places. For the fossil Lin picked up, a China University of Geosciences teaching biostratigraphy teacher said after watching, it is indeed from the Ordovician armenoceras, produced from marine limestone (i.e. the black marble). The preservation of large section hornstone fossil and complete, you can clearly see the tube part of beads and within the structure hierarchy, is a good specimen of science. >

大二男生小区内捡到四亿年前化石 在福州很少见 福州晚报(微博)9月17日讯(记者 陈丹 文 摄)大二男生放假回家过中秋,在小区草地上看到一块被遗弃的大理石,其中竟裹着4亿多年前的动物化石——阿门角石。这意外的中秋“礼物”令林翔鸿欣喜不已。大理石底座花纹很特别林翔鸿家住在仓山福湾新城,今年读大学二年级,因台风学校提前放假,14日14点多就回到了家。当他背着行李经过小区楼下的一片草地时,被一块圆饼状大理石吸引住了。小林是个化石“发烧友”,平日走路总爱盯着地面上的石头看,出于习惯,他随手翻了下这块废弃的大理石,却惊讶发现,石头里有一大截特别的花纹。虽然学的是数字媒体专业,但小林从小就喜欢收集古生物资料,还加入化石论坛,在学校办过化石展,他一眼认出这特别花纹其实是化石,而且是阿门角石。小林仔细观察,发现石头中间安装有螺母螺帽,和家中衣帽架底座一模一样。估计是谁家衣帽架坏了,底座就被随手丢在草丛里。如此完整化石在福州很少见“没想到中秋回家还能捡到化石!”小林把捡到的化石拍了照片,发给熟悉的古生物专家、化石爱好者们,大家也都认为这是化石,都称这是中秋“福利”。昨日记者在小林家中看到,这块大理石和普通石头没什么两样,不过里面有一截类似车轮印的白色花纹。小林告诉记者,阿门角石是古无脊椎动物,生活在4亿多年前的奥陶纪,现已灭绝。它是现代鹦鹉螺的近亲,也是奥陶纪地层最常见的化石之一,常见于各种灰岩质建筑石材中。“经过推测这块化石来自我国北方地区的奥陶地层,而且截面保存完好,角石的体管以及隔板等生物结构保存清晰,壳体全部方解石化,化石标本长23厘米。”小林认为,这块化石的原产地在4亿多年前是一片海洋。据了解,市民挖掘普通化石标本如三叶虫、头足类化石等并不违法,但如果私自贩卖大量化石盈利,则违反了相关法规。小林说,这块化石不能买卖,有较高的科普价值。“这么大个,我在福州还是头次见到,一般角石仅露出5厘米左右。”小林说,自己在福州很多地方发现过化石,例如他曾在福大旧校区、西湖公园等地发现过石材中藏着化石。对于小林捡到的这块化石,中国地质大学一位教古生物地层学的老师看后表示,这的确是来自奥陶纪的阿门角石,产自海相灰岩中(即那块黑色大理石)。这块角石化石的截面保存大而完整,可以清晰看到环节珠和内体管,结构层次分明,是个不错的科普标本。>相关的主题文章:
