The smallest dinosaur footprints

Original title: Liangshan zhaojue: save the dinosaurs "foot print"

Reporter Xu Xiangdong

Not only found the world's smallest dinosaur footprint of only two centimeters in length

This group of six batches of dinosaur footprints have been found

But the first dinosaur footprints have been destroyed, how to protect potential, such as pressing

Recently, from China, the expert on dinosaur tracks from the United States and South Korea announced in zhaojue County in Liangshan Prefecture, Sichuan province, Yang mozu before they found a group of dinosaur footprints, was identified as the smallest dinosaur footprints have been found in the world. This dinosaur is known as Tiger trail (Minisauripus), only about 2 cm in length.

In recent years, zhaojue County have uncovered fossilized dinosaur footprints. On May 1, zhaojue County pipe Institute told the liberation of Russia than this huaxi City newspaper reporter, in recent years, Luo Ga three mining areas in the County, once again found a large group of dinosaur footprints, hundreds of footprint formed a clear "z"-shaped route. This is the sixth issue of dinosaur footprints found in the local group, is the largest group of dinosaur tracks.

However, more than three Luo Ga located in the mine area, long-term ore mining, has original natural and ecological destruction. By mining blasting rocks continue to slide, was first discovered by a group of dinosaur footprints has been destroyed on the ground no deposit. While other tracks also faces "lost" danger.

How as soon as possible to protect the dinosaur footprint fossils? Therefore calls for the liberation of Russia than for many years, but the effect is not the best, still faces a series of challenges.

　　Rana chaochiaoensis Jing Shi "long mark"

In the Liangshan zhaojue County, found and identified the smallest dinosaur footprints in the world, only two centimeters in length. Not only that, but since the early 90 's, group of 6 batches of dinosaur footprints have been found. Zhaojue rich "Dragon's footprint" amazing.

Expedition discovered the world's smallest dinosaur footprints in July 2014, by young paleontologists in China, China University of Geosciences (Beijing) doctoral student XING Lida group leader, the world authoritative dinosaur expert, University of Colorado at Denver, Martin · Professor Lockley, as well as the Korea Teachers College Professor Jin Zhenglv expert to join the joint expedition, Liangshan zhaojue county authorities mozu under a collapsed wall in dozens of dinosaur footprints, was investigated.

In April this year, determined through scientific research, Yang mozu the dinosaur tracks, as the smallest dinosaur footprints in the world, its survival during the Cretaceous. The research results of the expert group, Elsevier publishing group of palaeogeography, Paleoclimatology, Paleoecology of periodicals were published on, the dinosaur footprints, called the Tiger trail (Minisauripus).

XING Lida said, the dinosaur footprints, not only compact, but rare, which puzzle quite a bit. Common dinosaur tracks 20 to 30 cm in length, but Yang mozu Xiang Xiao long tracks, only about 2 cm in length.

"This means that they trace of body length size of a bird, which turned the traditional thinking of people: not all dinosaurs are giant. Owner of the small footprint, possibly with some kind of furry Compsognathus class has a close relationship. "XING Lida said.

80 's of last century, scholars in Emei, Sichuan dragons were first discovered footprints. In 2002, Mading·luokeli Professor and scholar of the China geological survey Bureau in Shandong Junan found similar footprints. In contrast, zhaojue County of Tiger footprints preserved in good condition, sharp toe marks are very clear, and this means that they are carnivorous dinosaurs. Also, pace according to their length, speculated that this batch of Dragon run speed of up to 22.5 kilometers per hour.

Mading·luokeli argues that Tiger footprints discovered again has a profound significance in ancient geography. In the early Cretaceous, the dinosaur tracks in East Asia, mainly fine toe small theropod and a variety of bird feet, these footprints show a strong regional, such as Drake footprint currently appears only in East Asia, elsewhere but have not found, which may be related to ancient geography.

　　Zhaojue in groups have been found in batches of six tracks

Actually, this isn't the first dinosaur footprints found in zhaojue County. From the 90 's of the last century to the present, zhaojue County, have been uncovered dinosaur left "foot printed". In 2013, also found Asia's first swimming dinosaur footprints on the ground. This huaxi City newspaper reporter has also accompanied experts, participated in many of the County's investigation.

These dinosaur footprints, the largest, is more than three Luo Ga group of dinosaur footprints. Zhaojue County, longtime local dinosaur footprints Guan suo, Director of the Russian liberation told reporters that three Luo Ga dinosaur group, located in zhaojue County, Sanhe Township c Luo Ga than on mine. Since the early 90 's, due to mining and blasting, steep cliffs, exposed groups of dinosaur tracks in succession, has found thousands of.

Not long ago, on a rock in the Luo Ga three mining areas, again found dinosaur footprints. Russian liberation said, this is the sixth group of dinosaur footprints found on the ground, in an area of about 400 square meters of rock, there are hundreds of footprints, constitutes two routes. One route is about 60 meters long, a theropod dinosaur footprints, a single dinosaur footprints, 25 cm long, single step length 96 cm; another route is 65 meters long, is a sauropod dinosaur footprints, and line spacing 25 meters, a single footprint length 35 cm, width 30 cm, single-step length 135 cm.

Russian footprints here than the liberation group, named "f" here with the original discovery of "e" trail group into a, a combined footprint is approximately 1000, a total of 9 March route. These dinosaur footprint size, have deep and shallow, the route also intertwined, is very interesting.

　　"Long mark" protection dilemma

In zhaojue pipes, Director of the Russian liberation, removing the conceptual problem, Gu Long trackways protection and real-problem is that local resources are limited, related departments to pay enough attention to. He has repeatedly stressed that dinosaur tracks had once destroyed, cannot be recycled, then it is too late.

　　Warning signal for the first batch of dinosaur footprints has been destroyed

Zhaojue County, was first discovered by a group of dinosaur tracks, also in three Luo Ga than mine. These footprints, and have now ceased to exist, which are deeply saddened by the liberation of Russia.

Russian liberation said that the first dinosaur footprints found in September 1991, when local opened a copper mine blasting, Pine Mountain earthquake, rock slide, which exposed dinosaur footprint. But at the time no one knew, so I didn't report. Until 2004, was confirm as paleontology trail.

In Russia than the liberation of the computer, these tracks are stored undamaged pictures. He said that footprint in the mining districts east of the rock, an area of about 1500 square meters, there was ordering sauropod dinosaurs walking route 12, tracks more than 300 more, are clearly visible. At that time, the County also organized personnel to inspect. According to, there are 6 tracks routes is left by the larger dinosaurs: the single biggest footprint, length 62 cm, width 60 cm, span length 91 cm in a single step.

However, as the mining continues, these dinosaur footprints, now collapsed, buried. Russian liberation said, although other dinosaur footprints preserved in good condition, but due to the lack of specific protective measures, also faced the risk of destruction.

　　Conception differences should protect the foot print

　　Zhaojue County, the dinosaur tracks, should be protected?

As Wen Guan suo, Director of the Russian liberation, has been holding a protective attitude, and to this end calls for. Russian liberation said, frequently found dinosaur tracks from the current information can be seen, during the Mesozoic era, Rana chaochiaoensis area has a variety of dinosaurs in this life. These ancient relics, palaeogeography, Paleoclimatology, paleontology, paleoecological environmental studies to provide excellent information. Therefore, Rana chaochiaoensis dinosaur tracks survive and appeared, in fact, precious, protection, research and development has value for its protection, attracted the attention of authorities.

Expert XING Lida also believed that the footprints of these billions of years from now, it is necessary to protect. Dinosaur tracks and bones have irreplaceable roles, skeletal fossils of dinosaurs died only fragmentary information, but footprints saved, are dinosaurs in the everyday life of the moment, can not only reflect the living habits of the dinosaurs themselves, behavior, and can also explain the relationship between dinosaurs and their environments.

However, the concept remains. Some people think that is not a dinosaur bone fossils of dinosaur footprints, protect it, what's the value? Even believe that these tracks is just some holes in the stone, not necessary for protection. In this regard, the liberation of Russia than indignation. He said that as a natural heritage, dinosaur tracks had once destroyed, cannot be recycled, then it is too late. Moreover, relying on the long trail, can also be used for tourism development, promote industrial development. "This is a treasure, a lot of people do not realize it. ”

　　Protection problem the biggest problem where money comes from

How to protect a dinosaur footprint? Russian liberation said, according to China's regulations on protection of the fossils of the seventh article, large or concentrated distribution of the higher plants, fossil, fossil invertebrate and vertebrate trace fossils such as tracks, should be listed as key protection of fossils. His suggestion is that local nature reserve should be established to build Dinosaur Museum is, for offsite protection.

However, protection has been facing challenges. On one hand, zhaojue County, is a State-level poor counties, to take out the construction needed large sums of money, financially very difficult indeed. Russian liberation believes that the most important, is enough attention to local authorities on this matter. Fossils of land and resources departments should, zhaojue County, have no money to finish, so he turned to superior departments of land and resources, but didn't get a clear response.

For protection of Rana chaochiaoensis dinosaur footprint, XING Lida has also put forward his views, that is, protection in the field experience for reference. Important footprints, captured and placed in a museum or gallery for offsite protection. Conditions of in-situ protection, it is best to site protection housing.

At present, Chongqing qijiang, yanqing County, Beijing, Gansu province, and liujiaxia, have a successful case of dinosaur footprints. Among them, Chongqing qijiang dinosaur footprint fossils found in-situ conservation and development became a leisure attraction. Liujiaxia dinosaur footprint fossils located in Gansu, liujiaxia dinosaur national geopark was established. Beijing yanqing dinosaur footprint fossils from 2011 after its discovery, local protection measures have been taken, establishment of fossil reserves, and arrange to patrol throughout the day, while new road construction around protected areas.

　　"Footprints of the Dragon" value

Dinosaur tracks and bones have irreplaceable roles, skeletal fossils, dinosaurs died only fragmentary information, but footprints saved, are dinosaurs in the everyday life of the moment, can not only reflect the living habits of the dinosaurs themselves, behavior, and can also explain the relationship between dinosaurs and their environments.

　　"Footprints of the Dragon" protection

According to China's regulations on protection of the fossils of the seventh article, large or concentrated distribution of the higher plants, fossil, fossil invertebrate and vertebrate trace fossils such as tracks, should be listed as key protection of fossils.

　　Know about

　　Dinosaur footprint fossils come from

According to geology experts, about more than 100 million years ago, and now fossil found, was still a lake. Dinosaur footprints after walking in the sand, covered by sediments formed fossils, later fossil strata at the bottom off, exposed fossils.

四川发现最小恐龙足迹 首批足迹因采矿被破坏|恐龙|足迹_新闻资讯
昭觉发现的第一批恐龙足迹群，现已遭破坏成为一片乱石。岩壁上纵横交错的便是恐龙足迹。

最小的恐龙足迹

　　原标题：凉山昭觉：快救救恐龙的“脚板印”　

　　记者 徐湘东

　　这里不仅发现了长度仅两厘米的世界最小恐龙足迹

　　这里还先后发现了六批次的恐龙足迹群

　　但首批恐龙足迹已被破坏，如何保护势如燃眉

　　近日，来自中、美、韩三国的恐龙足迹化石研究专家宣布，他们之前在四川省凉山州昭觉县央摩祖乡发现的一批恐龙足迹，被确定为世界上已发现的最小恐龙足迹。这种恐龙足迹被称为小龙足迹（Minisauripus），长度仅2厘米左右。

　　近年来，昭觉县已发现多处恐龙足迹化石。5月1日，昭觉县文管所所长俄比解放告诉华西都市报记者，就在不久前，在该县的三比罗嘎矿区，再次发现了一处大面积恐龙足迹群，上百个足迹形成一条清晰的“Z”字形路线。这是目前当地发现的第六批恐龙足迹群，也是面积最大的恐龙足迹群。

　　但是，三比罗嘎地处矿区，长期的矿石开采，已将原来的自然生态破坏。因采矿爆破，岩层不断滑落，当地最早发现的一批恐龙足迹已被破坏无存。而其他足迹，也面临着“得而复失”的危险。

　　如何尽快地保护这些恐龙足迹化石？俄比解放为此奔走呼吁多年，但效果并不如意，仍面临一系列难题。

　　昭觉惊世“龙印”

　　在凉山州昭觉县，发现并确认了世界最小的恐龙足迹，长度仅两厘米左右。不仅如此，自上世纪90年代以来，已发现了6批次的恐龙足迹群。昭觉如此富藏的“龙之足印”让人叹为观止。

　　科考发现 世界最小恐龙足迹　　2014年7月，由国内青年古生物学者、中国地质大学（北京）博士生邢立达领队，世界权威恐龙足迹专家、科罗拉多大学丹佛分校马丁· 洛克利教授，以及韩国教员大学的金正律教授等古生物专家加盟的联合科考队，对凉山州昭觉县央摩祖乡一处崩塌岩壁下的数十个恐龙足迹，进行了考察。

　　今年4月，经科考研究确定，央摩祖乡的这批恐龙足迹，为世界最小的恐龙足迹，其生存时期为白垩纪。专家组的这一研究成果，在爱思唯尔出版集团的《古地理学、古气候学、古生态学》期刊上进行了发表，这种恐龙足迹，被称之为小龙足迹（Minisauripus）。

　　邢立达介绍说，这种恐龙足迹，不仅袖珍，而且珍稀，其中谜团还相当多。常见恐龙足迹长度在20至30厘米，但央摩祖乡的小龙足迹，长度仅有2厘米左右。

　　“这意味着，它们的造迹者的体长只有小鸟大小，这颠覆了人们的传统思维：恐龙并不都是庞然大物。这类小足迹的主人，可能与某种毛茸茸的美颌龙类有密切的关系。”邢立达说。

　　上世纪80年代，国内学者在四川峨眉首次发现了小龙足迹。2002年，马丁·洛克利教授和中国地质调查局的学者，在山东莒南又发现了同类足迹。 与之相比，昭觉县的这批小龙足迹保存得更完好，尖锐的趾痕异常清晰，而这意味着，它们为肉食性恐龙。而且，根据其步伐长度，推测出这批小龙的奔跑速度最高 可达22.5公里每小时。

　　马丁·洛克利教授认为，小龙足迹的再次发现，有着深刻的古地理学意义。在早白垩世，东亚的恐龙足迹，主要为细趾的小型兽脚类和多样化的鸟脚类，这些足迹显示出较强的地区性，比如小龙足迹目前只出现在东亚，其它地方却未曾发现，这可能与古地理因素有关。

　　成批成群 昭觉已发现六批足迹

　　其实，这并不是昭觉县第一次发现恐龙足迹。从上世纪90年代至今，昭觉县已经连续发现多处恐龙留下的“脚板印”。2013年，当地还发现了亚洲首例恐龙游泳足迹。华西都市报记者也曾随同专家，参加过多次在该县的考察。

　　这些恐龙足迹中，规模最大的，是三比罗嘎恐龙足迹群。长期关注当地恐龙足迹的昭觉县文管所所长俄比解放告诉记者，三比罗嘎恐龙足迹群，位于昭觉 县三河乡三比罗嘎的矿山上。从上世纪90年代以来，因采矿爆破，陡峭的岩壁上，陆续暴露出了一批批恐龙足迹，目前已发现了上千只。

　　就在不久前，在三比罗嘎矿区的一处岩石上，再次发现了大量恐龙足迹。俄比解放说，这是当地发现的第六批恐龙足迹群，在面积约400平方米的岩壁 上，共有上百个脚印，构成了两条行进路线。其中一条路线长约60米，为兽脚类恐龙足迹，单个恐龙脚印长25厘米，单步长96厘米；另一条路线长65米，是 蜥脚类恐龙脚印，与上条路线间距25米，单个脚印长35厘米、宽30厘米，单步长135厘米。

　　俄比解放将此处足迹群，命名为“F点”，此处与原来发现的“E点”足迹群连成了一片，加起来足迹数量约有1000个，一共有9条行进路线。这些恐龙足迹大小各异，有深有浅，行进路线也相互交织，十分有趣。

　　“龙印”保护困局

　　在昭觉文管所所长俄比解放看来，除去观念的问题，保护古龙足迹化石最现实的问题还在于当地财力有限，相关部门的重视程度不够。他一再强调，恐龙足迹一旦被破坏了，就不可能再生，到时候悔之晚矣。

　　警示信号 第一批恐龙足迹已被破坏

　　昭觉县最早发现的一批恐龙足迹，也在三比罗嘎矿区。而这批足迹，现已不复存在，这令俄比解放深感痛心。

　　俄比解放说，最早一批恐龙足迹发现在1991年9月，当地开铜矿爆破时，将山体震松，岩石滑落，从而暴露出了恐龙足迹。但当时无人认识，所以并未上报。直到2004年，才被确认为古生物足迹。

　　俄比解放的电脑中，还存放着这批足迹未被破坏时的照片。他说，足迹在采矿区东面的岩壁上，面积约1500平方米，上面有行进有序的蜥脚类恐龙行 走路线12条，足迹300多个，清晰可见。当时，县上还专门组织了人员进行考察。资料显示，有6条足迹线路是较大体积恐龙留下的：最大的单个脚印，长62厘米、宽60厘米，单步跨度长91厘米。

　　但是，随着矿山开采的继续，这批恐龙足迹，如今已被震垮、掩埋。俄比解放说，虽然目前其他恐龙足迹还保存完好，但因缺乏具体的保护措施，也面临着被破坏的危险。

　　观念分歧 该不该保护这些脚板印

　　昭觉县这些恐龙足迹，是否该得到保护？

　　作为文管所所长的俄比解放，一直是持有保护的态度，并为此奔走呼吁。俄比解放说，从目前发现的恐龙频繁往来的行迹信息可见，在中生代时期，昭觉 地区有各种恐龙在此生活。这些古生物遗迹，对古地理学、古气候学、古生物学、古生态环境学等研究提供了绝好资料。因此，昭觉恐龙足迹群的幸存与出现，实为 弥足珍贵，具有保护、研究和开发利用价值，对它的保护，应引起有关部门的重视。

　　专家邢立达也认为，这些距今上亿年的足迹，非常有保护的必要。恐龙足迹，具有骨骼化石无法替代的作用，骨骼化石保存的仅是恐龙死后支离破碎的信息，但足迹保存的，却是恐龙在日常生活中的一瞬间，不仅能反映恐龙本身的生活习性、行为方式，还能解释恐龙与其环境的关系。

　　然而，观念上分歧仍在。有人认为恐龙足迹又不是恐龙骨骼化石，保护它，有啥价值？甚至认为，这些足迹不过是石头上的一些坑坑洼洼，没保护的必 要。对此，俄比解放颇为愤慨。他说，作为自然遗产，恐龙足迹一旦被破坏了，就不可能再生，到时候悔之晚矣。况且，依托龙足迹，还可以进行旅游开发，带动产业发展。“这是财富，可不少人没意识到这一点。”

　　保护难题 最大难题钱从哪里来

　　到底该怎样来保护恐龙足迹？俄比解放说，根据我国《古生物化石保护条例》第七条，大型的或者集中分布的高等植物化石、无脊椎动物化石和古脊椎动 物的足迹等遗迹化石，应当列为重点保护古生物化石。他的建议是，当地应当成立自然保护区，建设恐龙博物馆，对足迹进行异地保护。

　　但是，保护却一直面临难题。一方面，因昭觉县是国家级贫困县，要拿出建设需要的大笔资金，财政上的确非常困难。俄比解放认为，最重要的，是当地相关部门对此事的重视程度不够。古生物化石应当为国土资源部门管辖，昭觉县没财力去完成，于是他求助于上级国土资源部门，却没有得到明确的回应。

　　对于昭觉恐龙足迹的保护，邢立达也提出了自己的观点，那就是，借鉴外地的保护经验。重要的足迹，采集下来，放在博物馆或者陈列室进行异地保护。有条件进行原址保护的，最好是现场建造保护屋。

　　目前，在重庆綦江、北京延庆，以及甘肃刘家峡，均有恐龙足迹成功保护的案例。其中，重庆綦江将发现的恐龙足迹化石进行原址保护，并开发成为一处 休闲度假景点。甘肃刘家峡的恐龙足迹化石群所在地，建立起了刘家峡恐龙国家地质公园。而北京延庆的恐龙足迹化石，从2011年发现之后，当地就采取了保护 措施，设立化石保护区，并安排专人进行全天巡护，同时新建公路也绕开保护区施工。

　　“龙之足印”价值

　　恐龙足迹，具有骨骼化石无法替代的作用，骨骼化石保存的，仅是恐龙死后支离破碎的信息，但足迹保存的，却是恐龙在日常生活中的一瞬间，不仅能反映恐龙本身的生活习性、行为方式，还能解释恐龙与其环境的关系。

　　“龙之足印”保护

　　根据我国《古生物化石保护条例》第七条，大型的或者集中分布的高等植物化石、无脊椎动物化石和古脊椎动物的足迹等遗迹化石，应当列为重点保护古生物化石。

　　知道一下

　　恐龙足迹化石从哪儿来

　　据地质学专家分析，大约在1亿多年前，现在的化石发现地，当时还是一片湖泊。恐龙在泥沙上行走后留下脚印，被沉积物覆盖形成化石，后来化石底部岩层脱落，化石因此暴露出来。
