Stone seams fossil of li of the ammonite before dig or dig out with a finger or sth pointed goes out 450 million years
Ammonite fossil forms sketch map
The ancient biology fossil that Zhang Wu art collects
A citizen goes to Wuhan favour apply autonomous prefecture of Miao Zu of the Tujia nationality benefit plain city visits his family, search 3 strange stone. Yesterday, via geological expert and appraisal of ancient biology expert, these a few stone all are to be apart from today the precious fossil 450 million years ago, and have higher research value. Geological expert appeals, should as soon as possible is built in place “ geological and vestigial groove guard “ , undertake protect and be developinged.
Before stone seams li of dig or dig out with a finger or sth pointed to go out 450 million years “ ammonite “ fossil
Zhang Wu art is worker of center of emergency treatment of the hospital that be the same as aid. Several days ago, he is taken the advantage of off to benefit countryside of dam of plain city wool visits his family. In the hill that in countryside of distance wool dam about 3 kilometers are in, he finds two be similar in shape “ conch “ stone, together black in fully red, another black in extensive is green. And in the clastic rock caboodle with not far be apart, he finds the stone with a yellow extensive that open system accidentally again, this stone resembles a stick, cross section still divides a layer, most among have whole body of be well versed in of centre of a stone, be just as rachis.
Yesterday, zhang Wu art is taking these stone and the local stone collection that take photograph, save geological and scientific institute with our newspaper reporter together. Chief engineer Miao always gets the better of Tan Qiuming of senior engineer of class of professor of center of this geological and vestigial evaluation and scientific research ministry two experts, the careful research that passes nearly 2 hours compares pair of discovery, be similar in shape “ conch “ stone is unexpectedly “ ammonite “ fossil; And that rock that grows about 20 centimeters “ maize “ it is “ hornstone “ fossil. These two kinds of ancient organisms all produce to be apart from now today 450 million years ago “ the Ordovician period “ .
According to expert introduction, “Ammonite “ and “ hornstone “ itself is not stone, live in the mollusc in ocean however, because encounter geological mutation, be buried by the instant at underground, lie between never to be seen again for a long time to petrifaction evolves and come slowly with air. The discovery of these fossil, geological to studying paleontology is mixed, provided valuable objective data.
3 have similar results before New Year, “Try to locate sth by following up a clue “ obtain strange stone again
Actually, be in early 2006 in September, zhang Wu art is in benefit plain visits his family the happy event that first time accident harvested in road. That time, he discovers the strange rock that has the figure like the leaf together from inside a lot of bizarre stone. Via saving appraisal of expert of geological and scientific institute, this is the fossil of trilobite, the time that this kind of trilobite appears also is the Ordovician period (one edition ever did our newspaper on March 20, 2007 reportorial) . “This, basic it is to press last time old road, go searching designedly. “ Zhang Wu art says, “And this discovery, the place before be apart from 3 years is apart from 500 meters only “ . According to Zhang Wu art is told, there still are a lot of grotesque rocks over, hide in remote mountains all the year round.
The expert appeals place as early as possible delimit geology groove guard
Zhang Wu art finds precious fossil from inside Li Chuanshan for two times, your rocksy people excited unceasingly, but also conveyed at the same time anxious. Tan Qiuming expresses, will study funds to ranking application, before leading geological researcher, toward Lichuanshi the ground makes an on-the-spot investigation.
According to Zhang Wu art is told, as a result of him not quite understand collect, “Ammonite “ fossil aboard is squeezed to defeat. And be in benefit plain place, because dwellers do not understand these rock at all, in quarry or attaint of the hard to avoid when building a road them — that half-baked that he discovers “ hornstone “ fossil is in what the clastic rock of a quarry finds in caboodle namely.
Tan Qiuming thinks, if ancient biology fossil is in,benefit plain large area exists thick and fast, suggest local government and branch of land natural resources, on the foundation of reconnaissance, as soon as possible compares fossil concentration, class to compare all ready region delimit to be “ geological and vestigial groove guard “ , carry out the protection that encircle the ground to fossil, prevent the excessive that be collected by excessive to dig. In the meantime, return the travel resource that can rely on place to have, integrated, dish vivid geological zoology travels.
