化石标本该如何鉴别呢？-欧洲杯在线开户

而倍受欢迎。中国的河南、四川、广东等很多地方都出土。

 

and it's very popular. henan, sichuan, guangdong and many other places in china have been unearthed.

 

在造假的古生物化石中，恐龙蛋是比较多的。市场上各种各样的假恐龙蛋价格很高。假恐龙蛋主要有：

 

dinosaur eggs are abundant in fake fossils of paleontology. the price of all kinds of fake dinosaur eggs on the market is very high. fake dinosaur eggs mainly include:

 

一、河床中的鹅卵石，一般选择大小适合比较圆滑的，然后在上面粘合一些已经破碎脱落下来的恐龙蛋皮。上世纪90年代初在河南西峡县，恐龙蛋大量出土时人们不要那些已经脱落的恐龙蛋皮，只要又大又完整的恐龙蛋，后来这些恐龙蛋皮由一些别有用心的人拣拾或低价收购。此类假恐龙蛋在与碎蛋皮之间的碎纹宽窄渐变不连续，纹路弯弯曲曲变化不自然，蛋皮局部和内部卵石有明显不吻合之处，多有“翘皮”现象。在碎蛋壳间的结合处，一般用红色土来填充。经过长期的摆放，有些蛋皮便自动脱落，里面的鹅卵石就会看清楚。

 

first, the pebbles in the river bed are generally chosen to be smooth in size, and then glued to them some broken and fallen dinosaur eggshells. in xixia county of henan province in the early 1990s, when dinosaur eggs were unearthed in large quantities, people did not want those eggshells that had fallen off, as long as they were large and complete. later, these eggshells were picked up or purchased at low prices by people with ulterior motives. this kind of pseudo-dinosaur eggs had discontinuous fragmentation width and gradual change between the fragmented eggshell and the fragmented eggshell. the curve and bending of the fragments were not natural. there were obvious discrepancies between the local and internal pebbles of the eggshell, and most of them had the phenomenon of "warping". at the junction of broken eggshells, red soil is usually used to fill them. after long-term placement, some eggshells will fall off automatically, and the pebbles inside will be clearly seen.

 

二、将不完整的恐龙蛋进行拼凑，如两个相近的半个恐龙蛋拼成一个完整的蛋化石，在粘合处用破碎恐龙蛋皮遮盖，最后用红色泥土涂抹缝隙。在河南西峡县很多家庭中都有这种拼凑粘合的恐龙蛋，每颗不少于200元。往往可以看到这种蛋化石有一整条破裂，表面的蛋纹即没有连贯性。

 

2. make up the incomplete dinosaur eggs, such as two half of the similar dinosaur eggs to form a complete egg fossil. cover the bonding area with broken dinosaur eggskin, and finally smear the cracks with red earth. many families in xixia county of henan province have this kind of patchwork and bonded dinosaur eggs, each of which is not less than 200 yuan. it is often seen that the egg fossil has a whole crack, the surface of which is not consistent.

 

三、在地层里常看到的含碳酸钙的钙质结核，这些结核经常掉入河中，泥砂颗粒粘附在表面，河干涸后，这些圆形的表面带有砂料的结核便显现出来，在破裂的结核中间，还能看到黑色或红色的色晕圈，人们误以为是蛋黄留下来的痕迹。它与真正的恐龙蛋的区别是，真蛋都是带有比较光滑的蛋皮，有均匀的蛋皮裂纹。这种石蛋给人的感觉是剩蛋核的恐龙蛋。

 

3. calcium nodules containing calcium carbonate are often seen in the stratum. these nodules often fall into rivers. mud and sand particles adhere to the surface. when the river dries up, these round nodules with sand on the surface appear. in the middle of the broken nodules, black or red halo circles can also be seen, which people mistakenly think are left by egg yolk. traces of coming. the difference between real dinosaur eggs and real ones is that real eggs have smooth skin and even cracks. the stone eggs give the impression of dinosaur eggs with egg nuclei left.

 

四、利用真恐龙蛋翻制模具，然后用石膏和水泥等材料制作，再配上真实的石头底座，仿真效果常常很好。这类蛋有单个和成窝十几个，像十几颗这情况就有赝品的可能。识别方法是：蛋的表皮不同，假蛋的表皮裂纹不自然，真恐龙蛋上所特有的蛋皮碎花纹翻具过程中是做不出来的，只是蛋皮上确实有凹凸的部位才能显现。蛋皮碎裂的缝隙真实的蛋可以发现蛋皮分层。假蛋与底座接触部位一般是石膏、水泥粘合，往往会找到缝隙或被挤出的粘合物，用湿布轻轻擦拭就可以去掉粘合处的涂色。

 

fourth, using real dinosaur eggs to make molds, then using gypsum and cement and other materials, coupled with real stone base, the simulation results are often very good. there are more than a dozen such eggs in a single nest, such as a dozen eggs, which can be counterfeited. recognition method is: the skin of eggs is different, the cracks of the fake eggs are not natural, and the unique break pattern of the real dinosaur eggs can not be made in the process of turning over, only the concave and convex parts of the eggshell can be shown. real eggs can be found in the cracks of the eggshell. layering of the eggshell can be found in real eggs. the contact area between the false eggs and the base is usually bonded with gypsum and cement. the cracks or extruded bonds are often found. the color of the bond can be removed by gently wiping with a wet cloth.
