Nanyang Xixia dinosaur eggs
1993, scientists in western China's Henan Nanyang Xixia County found a large number of dinosaur eggs. In the past, human beings discovered a total of more than 500 pieces of dinosaur egg fossils, unearthed this time Xixia dinosaur eggs as many as 5,000 pieces, there are no estimates on the excavated pieces. For a time, shocked the world. But why so many dinosaurs have come to Xixia afterlife eggs? Scientists have speculated that dinosaurs like water, sunny, higher ground to lay eggs. Xixia precisely to meet these conditions. Xixia ancient geological times is a basin, a lot of lakes and swamps, warm and humid, suitable for dinosaurs to survive.
gradually discovered by the dinosaur egg fossils to confirm: dinosaurs and modern reptiles and birds, can also give birth with a hard shell egg. some of the egg fossils found in even the little unhatched dinosaur skeleton! sometimes nests of dinosaur eggs found near found the remains of a large dinosaur. Thus, like the small dinosaurs and birds, will instinctively stay in the nest, regardless of what happens to their parents not to leave. Some dinosaur nest in close proximity to each other, experts speculate therefore Dinosaurs may have social habits. What is startling is, eggs is not as you'd think. If the eggs is proportional to the size and shape of dinosaurs, then the egg will be hard enough so that small dinosaurs could not hatch; and could not let enough oxygen into the egg, the supply of small dinosaur breath.
stolen dragon egg, Chi Long, Long teeth hurt these small theropod dinosaur eggs normally elongated; Horse Gate River Dragon, Diplodocus and Brontosaurus These four-legged wading hunk of the eggs are round; duck-billed dinosaur favor ornithopod Health oval eggs; The Mesozoic overlord - Tyrannosaurus rex eggs see like, there is no definitive explanation.
Xixia Basin, the world's rare dinosaur egg fossils, according to the experts, after the site visit accustomed seven burial site of dinosaur egg fossils, of which Dan Xixia County Town on the western tilt of the highest concentration of Tin. Another urban and rural areas in the county Yang Zhao Yingcun Cretaceous strata in the southwest, in counting to a large number of dinosaur egg fossils, but too discovered fossils of dinosaur bones.
experts say, the basin fossil dinosaur eggs found in the characteristics, namely, the distribution area, in Xixia County, Dan Town, Shenyang Urban and Rural, Rural Red Eyebrows Neixiang 40 square kilometer area can be found traces of dinosaur activities. The second is buried concentration profile can be observed from the three fossil beds, nest-like distribution of egg fossils were arranged in a order, ten to thirty per litter several months. Third, the number of rich, has discovered that thousands of pieces, no less than the amount estimated to total tens of thousands of burial, and its abundance of rare in the world. Fourth, the original state of well-preserved fossil basically have not been confused and devastated afterward,wastage of nourishment. Also you tin arrange some fruit, in addition to the surface of a small amount of egg shell by a slight depression rock extrusion, the most complete ever, which is unique in the world.
Xixia dinosaur egg fossils among the distribution and types of < br> a large number of fossils in the wide distribution of Xixia, are: Dan, water, Yangcheng, carriage returns, Wuli Bridge, Ding River, Chong, Xiping, Tian customs, and other eight towns and Yangcheng, Dan 2 towns water scope. Xixia Basin in southwest Henan representative fossils of dinosaur eggs intensive areas, the wide distribution of dinosaur egg fossils, the sheer number of types of diversity, preservation of the perfect, rated highest in the world, is the world's wonders and rare paleontological treasure trove of natural history's treasures. At present, China has found fossils of dinosaur eggs, 8 families, 12 genera, 25 species of dinosaur egg fossils Xixia basin there are 6 families, 9 genera and 13 species, accounting for the total number of 1 / 2, the world's total 1 / 3. which has the world's unique Xixia long cylindrical egg (Longiteresoolithus xixiaensis) and rare desert unique prismatic eggs (Prismatoolithus gebiensis).
fossilized dinosaur eggs
now displayed in front of human and other places Xixia Basin fossils of dinosaur eggs, the eggs are not emulating the above, exhibit of dinosaur egg fossils distribution ought be hanging behind together, is their original natural formation state. dinosaur egg fossils Why are compaction intensity and inversely proportional to the porosity of sand, sandstone porosity decreased with increasing depth in the 350m depth, porosity of 38%, while in the 350m the emulating, with the depth of the porosity of sandstone amplify straightforward reduce to 6 000m depth, porosity of 18% or so. This is due to plastic deformation adaptability cuttings is promoted with depth caused by the deepening. Thus, the lower portion of the fossil dinosaur eggs was stronger than the plastic distortion of rock The upper part of the rock, the compaction, the lower part of the rock dinosaur eggs become less dense and tough to change their top form. From the outlook of sedimentology, sedimentary layers of the lower part of coarse motes, meantime the upper part is relatively smaller, are graded on This is true for graded rock. dinosaur eggs between the upper strata of nice motes suspended in the clay filling material more lightly, lower than its large adhesion. Thus, the weight of real rock base of the egg, not cozy to happen repeatedly in the late deformation, adhesion is small, simple egg fossils and rocks from the prologue; eggs lower than the upper strata of the real pressure, fracturing lightly occur another in the late deformation, and adhesion to a large, egg and rock from fossils is not easy to open; so from the underground rock in the excavation of dinosaur eggs are poured out of the The mechanism of
fossils of dinosaur eggs in Xixia Basin dense in certain zones and layers in a large number of enrichment and the enrichment machinery of their formation conditions are many.
dinosaur egg production rate of high
Yang Zhongjian ( 1965) Nanxiong in the study of Guangdong, and Jiangxi Ganzhou Shixing egg fossils, he had pointed out that nest of dinosaur eggs up to more than 40. In Xixia, Xichuan, Summer Pavilion - Takaoka and Wuli River basins, the nest of dinosaur The number of eggs usually 5 to 20, at least four, up to 53. Xixia dinosaur egg fossils Yang urban and rural areas up to four intensive / m2.
dinosaurs gregarious habits
a basin, alternatively merged within a few thousand years or more in the long period of 6 or 7 ~ ~ 7 8 dinosaurs lived, the dinosaurs can not be phoned social or miscellaneous behavior. However, in the Xixia Basin, in a rock, there are more than the same nest discovered fossils of dinosaur eggs, which can not but calculate namely is another from the same species of dinosaur eggs produced, they can arrange their eggs together in a geographical area, propagate, they are most probable very similar aboard the habits of life, there is may lead a social life.
1, dinosaur eggs in Xixia bason scheduleal
dinosaur egg fossils were found in sedimentary layers in rhythmic wheels, the upper strata, beneath the number of egg layers m often scouring the end of construction. It reflects a period of dinosaur eggs, water kinetic vigor is small and is ahead the appearance of variant overflow, this is the spring and summer period at the turn. dinosaur eggs selective this season , will inevitably lead to enrichment of the characteristics of dinosaur eggs.
2, dinosaur eggs hatching low
to Late Cretaceous dinosaurs low reproductive capacity of animals, many of unfertilized eggs, with long-term high temperature, is not conducive to the dinosaur survival, the egg hatching rate is very low. Thus, egg production a lot, but was hatched fewer eggs during this period to form a dense, particularly in the case of enrichment.
3, quick burial and a settled tectonic environment
birth to a large number of dinosaur eggs, although fewer hatched into a dinosaur, and a large number of eggs not hatching eggs to become fossilized, have to be quickly buried by sediment collection of a large number. In the Late Cretaceous World during the manoeuvre of crustal movements in the area to the chief motion, there is no aggression of mantle substance into the basin to Chung, a relatively stable tectonic environment after the eggs have not been huge in the formation of the crustal movement reasoned by the erasure, these factors also the formation of a large number of dinosaur egg fossils in this area as a ingredient enrichment.

This is a land full of sorcery and hope; a land full of vitality and creativity; one is full of endless temptation and phantom land.
This is the China Central Mountains, the Qinling orogenic belt of the classic Variety Lot mmm Nanyang China, the world One of the four major orogenic belt, with a typical, representative, rarity and significance of international comparisons.
Mountain, is a composite orogenic belt of continental geology textbooks, biological transition zone between North and South, the Yangtze River, Yellow River, Huaihe River watershed, is the northern subtropical mountain symbol of the ecological environment, the home of a Cretaceous dinosaur hh
here, mountainous pinnacles, Lin gray, fantastic springs, cascades, flowers, majestic mixture with the natural quiet wan, active Delicate coarse and slight, and Mao, tin be depicted as beautiful scenery and purity.
let us into the Mountain, Funiushan into this magical world geological park in the world, tracking the trajectory of crustal evolution and enjoy the magnificent mountain architecture, appreciation of biological colorful world, taste and glorious cultural heritage of the heavy.
80 years in the 20th century, Xixia Basin, the discovery of dinosaur egg fossils to become a major news shocked the whole world. known as the scientific discovery that shocked the world and ninth in the world big miracle. fossils of dinosaur eggs buried here, with its sheer number of wide distribution, preservation of the perfect type of diversity, called the world. have found fossils of dinosaur eggs, 6 families, 9 genera and 13 species. accounting one half, one third of the world. which Zhuge Nanyang Long, Xixia long cylindrical egg, egg fossils Gobi prism is a worldwide unique and rare type. Interestingly, where different types of dinosaur egg fossils there are different layers Fu, dozens of pieces of dinosaur eggs were living in a room, multi-piece nest of dinosaur eggs, dinosaur eggs, the line of Dan Chengping, irregular and radial arrangement of pairs of long cylindrical dinosaur egg fossils are twin The best physical evidence of tubal egg. which have even now hatched large numbers of fossils of dinosaur eggs, it indicates that the genetic evolution of life, a lack of,shanghai escort, or yet to crack the mystery of the natural Nanyang Xixia dinosaur eggs
In 1993, scientists in western China's Henan Nanyang Xixia County found a large number of dinosaur eggs. in the quondam, person beings discovered a total of more than 500 pieces of dinosaur egg fossils, and this dinosaur eggs unearthed in Xixia up to 5,000 pieces, there are no estimates on the excavated pieces. For a time, shocked the world. But why so many dinosaurs have come to Xixia afterlife eggs? Scientists have speculated that dinosaurs like water, bright, terrain than a high place to lay eggs. Xixia just to encounter these conditions. Xixia archaic geological times is a basin, a lot of lakes and marshes, warm and humid, suitable for dinosaurs to survive.
along the fossils of dinosaur eggs have been discovered to confirm: Dinosaurs and, like modern reptiles and birds, also born with a hard shell egg. some of the egg fossils found in even the mini unhatched dinosaur skeleton! periodically found approximate the nests of dinosaur eggs, found a large dinosaur remains. Thus, small dinosaurs and birds, as will instinctively linger in the nest, no stuff what their parents do not leave. Some dinosaur nest in close vicinity to every other, experts accordingly speculated that dinosaurs may have social habits. ORDER Surprisingly, eggs is not as you'd think. If the eggs is proportional to the size and fashion of dinosaurs, then the egg ambition be hard enough so that small dinosaurs could not hatch; and can not let enough oxygen into the eggs the afford of small dinosaur respiration.
stolen dragon egg, Chi Long, Long teeth hurt these small theropod dinosaur eggs usually elongated; Horse Gate River Dragon, Diplodocus and Brontosaurus big male to walk the 4 legs The eggs are round; duck-billed dinosaur like ornithopod Health oval eggs; The Mesozoic overlord - Tyrannosaurus rex eggs look like, there is no definitive explanation.
Xixia Basin rare in the world of dinosaurs egg fossils, according to the experts, after the site visit confirmed seven burial site of dinosaur egg fossils, of which Dan Xixia County Town on the western slope of the highest concentration of Tin. Another urban and rural areas in the county Yang Zhao Yingcun Cretaceous strata in the southwest, in addition to a large number of dinosaur egg fossils, but also discovered fossils of dinosaur bones.
experts mention, the basin fossil dinosaur eggs found in the characteristics, that, the distribution area, in Xixia County Town Dan, Yang urban and rural areas, inner Red Eyebrows rural county town about 40 square kilometer area can find traces of dinosaur activities. The second is buried concentration outline can be scrutinized from the 3 fossil beds, nest-like distribution of egg fossils were arranged in order, to a dozen per trash thirty several months. Third, the number of wealthy, has discovered that thousands of pieces, no less than the quantity estimated to total tens of thousands of burial, and its plenitude of rare in the world. Fourth, the original state of well-preserved fossil basically have not been late disruption and destruction, in addition to the surface of a small amount of egg shell by a puny depression squeezing rock, the most complete ever, which is unique in the world.
Xixia distribution within the fossilized dinosaur eggs and fossils species
within Xixia broad distribution of large, are: Dan, water, Yangcheng, chariot returns, Wuli Bridge, Ding River, Chong, Xiping, Tian customs, and other eight towns and Yangcheng, Dan 2 towns within the water. to Xixia Basin southwestern Henan representative fossils of dinosaur eggs intensive districts, the wide distribution of dinosaur egg fossils, the sheer number of types of diversity, conservation of the absolute, rated maximum in the globe, is the world's marvels and infrequent paleontological treasure trove of natural history's treasures. At present, China has base fossils of dinosaur eggs, 8 families, 12 genera, 25 species of dinosaur egg fossils Xixia basin there are 6 families, 9 genera and 13 species, accounting as the aggregate number of 1 / 2, the world's aggregate 1 / 3. which unique to the earth long cylindrical eggs in Xixia (Longiteresoolithus xixiaensis) and rare desert unique prismatic eggs (Prismatoolithus gebiensis).
fossilized dinosaur eggs Xixia Basin and other places in front of dinosaur egg fossils, eggs are not following the above, display of dinosaur egg fossils distribution should be hanging back together, is the formation of their original natural state. Why are dinosaur egg fossils inversely proportional to the porosity of sandstone porosity decreased with increasing depth in the 350m depth, porosity of 38%, while in the 350m below the porosity of sandstone linear decrease with the depth increase, to 6 000m depth,beijing escort, the sandstone porosity is 18%. This is due to plastic debris with the depth of plastic deformation caused by the deepening and enhancement. Thus, the lower part of the fossil dinosaur eggs plastic deformation of the rock is stronger than the upper strata, the pressure compaction, the lower part of the rock dinosaur eggs become less dense and difficult to change their top form. From the perspective of sedimentology, sedimentary layers of the lower part of coarse particles, while the upper part is relatively smaller, are graded on the rocks for all graded is so. dinosaur eggs between the upper strata of the finer particles of clay suspended easier filling material, the cohesion than the lower large. In this access,beijing massage, the weight of real rock bottom of the egg, not easy in the later stage deformation, bonding is small, easy egg fossils and rocks from the opening; eggs than the upper part of the lower pressure of real rock, fracturing easily happen again in the late deformation, and adhesion to a large, egg and rock from fossils is not easy to open; Therefore, excavation of rocks from the ground Dinosaur eggs are poured out of the Basin dense dinosaur egg fossils, and layers in a certain area within a large number of enrichment and the enrichment mechanism of their formation conditions are many.
dinosaurs
Yang Zhongjian high egg production (1965) in the learn of Guangdong Nanxiong , Ganzhou, Jiangxi Siheung and egg fossils, he had pointed out that nest of dinosaur eggs up to more than 40. In Xixia, Xichuan, Summer Pavilion - Takaoka and Wuli River and other basins, the number of dinosaur eggs in a nest usually 5 to 20 gold, by fewest four, up to 53. Xixia dinosaur egg fossils Yang urban and rural areas up to four intensive / m2.
or mixed social habits of dinosaurs
a basin, up to tens of millions of years within a period of 6 to 7 or 7 to 8 dinosaurs lived, the dinosaurs can not be called social or mixed behavior. However, in the Xixia Basin, in a rock, the more fossils of dinosaur eggs the same nest found that this can not but think that is different from the same species of dinosaur eggs produced, they can lay their eggs together in a geographical area, breed, they are most likely very similar on the habits of life, may lead a lonely life.
1, dinosaur eggs in Xixia basin timeal
dinosaur egg fossils were found in sedimentary layers in rhythmic cycles, the upper strata, egg layers several meters below the end of erosion are often constructed. This reflects a period of dinosaur eggs, water kinetic energy is small and is before the arrival of another flood, this is the spring and summer period at the turn. dinosaur eggs selectivity of this season, will inevitably lead to enrichment of dinosaur eggs features.
2, dinosaur eggs hatching low
to Late Cretaceous dinosaurs cheap reproductive capability of animals, many of unfertilized eggs, with long-term tall temperature, is not conducive to the survival of dinosaurs, their eggs hatch rate is quite low. Thus, egg making a lot, but was hatched fewer eggs during this time to manner a dense, especially in the circumstance of enrichment.
3, rapid burial and tectonic permanence of the environment < br> birth to a large number of dinosaur eggs, although less hatched into a dinosaur, and a large number of eggs not hatching eggs to become fossilized, must be quickly buried by sediment accumulation of a large number. In the late Cretaceous period, the crust movement This area is mainly down movement, there is no intrusion of mantle material to flock to the basin, a relatively stable tectonic environment after the eggs have not been big in the formation of the crustal movement caused by break to the formation of these factors are a large number of dinosaur egg fossils in this area enrichment of a factor.
