A team of scientists from Canada and Taiwan, China, said on the 14th that they studied fossils of dinosaurs found near Luzhou, Jiangxi Province, China and found that the fossils contained ovaries and fallopian tubes and two dinosaur eggs that had not yet been produced. This rare discovery reveals the kinship of dinosaurs and reptiles and birds. Scientists published an article in the online edition of the American "Science" magazine that said this group of dinosaur fossils includes several sections of the sacral and coccygeal bones, sacrum, ischium, and part of the leg bones. Among the most important findings is a relatively complete dinosaur. In the pelvic structure, there are two dinosaur eggs that have been formed but have not yet been produced. Scientists have discovered that its reproductive system shares many similarities with modern birds, and there are many places that are transitional, like crocodile and other relatively old reptiles. For example, the dinosaur has two ovaries and two fallopian tubes. This primitive feature is very similar to a crocodile, and birds have only one ovary and fallopian tube. Every time a modern bird produces an egg until it fills a nest, and a crocodile and other reptiles produce a nest of eggs at a time, how do dinosaurs lay eggs? The researchers said that the way the dinosaur lays eggs is also somewhere in between. The researchers wrote in the paper that the dinosaur should be paired to lay eggs. It lays out two eggs and arranges them, and then begins to give birth to a pair, until a dozen eggs fill up. Scientists had speculated in the past that the appearance of dinosaur eggs in pairs may be the result of dinosaur parents disguising their eggs in order to keep their offspring, and new findings suggest that “this is more likely to result from the simultaneous production of two eggsâ€. The two eggs that appear in pairs in the pelvic fossils are close in size to pineapple and resemble potatoes and have grown into hard shells. The eggs of a crocodile egg have multiple, tough shells, and the bird's eggs have a single layer and a hard shell. The researchers believe that the egg produced by this dinosaur should be more like a bird's egg. According to reports on April 15th by msnbc.com, scientists have discovered that dinosaur egg fossils resemble bird embryonic reproductive structures. This rare and major discovery has given people new insights. It provides a scientific basis for the reproductive mechanism of earth creatures and the gradual evolution of dinosaurs into birds. In a scientific journal issued on April 15, a researcher who reported on this major discovery said that this is the first time in history that people have discovered embryonic reproductive structures similar to birds in dinosaur egg fossils. Scientists have discovered that the process of dinosaurs spawning is somewhat like a modern crocodile. On the other hand, it is like a modern bird. The crocodile and its similar primitive reptiles have two ovaries so that they can produce a lot of eggs at a time. But birds have only one ovary, so they can only produce one egg at a time. Scientists say that dinosaurs have some kind of connection with current birds, and that dinosaurs lay their eggs between reptiles and birds. Dinosaurs spawn more than one egg at a time, but only one egg can be produced from one ovary at a time. Sato Yuki of Canada's Ottawa Museum of Nature said that the evolutionary theory of birds from dinosaurs has been recognized by many researchers. This major discovery provides strong evidence for this hypothesis. It complements people's existing theories. Sato said that scientists had also found circular objects around the dinosaur skeleton. People suspect that this is a dinosaur egg, but because these round objects have no shells, people are not sure. She believes that in the Museum of Natural Science in Taiwan there are eggs with shells that have been excavated from China. This is the first time people have found solid evidence. Scientists are studying a dinosaur called the stalking dragon. This type of dinosaur is about 10 feet to 13 feet long and is a subgroup of the arachnids of carnivorous dinosaurs. People have long believed that such dinosaurs are the ancestors of modern birds. The remaining eggshell found this time looks like a pineapple, about the size of a potato. According to the report, the similarity of the size of the dinosaur eggs discovered in this report indicates that these animals have two fallopian tubes, one for each egg. "This discovery has given people a deeper understanding of the evolutionary process of dinosaur biology and birds," said Matt Carrano, director of the National Museum of Natural History of Washington, D.C., "It provides scientists with a special understanding of biological evolution. The stage has opened up a new path.†This special type of dinosaur has the original characteristics of birds, but it also maintains the reptile's own characteristics. It has two fallopian tubes, but they only produce one egg at a time. Such dinosaurs are among the birds and reptiles. Carrano also said that this discovery has made people more aware of the bird's development process. According to this discovery, the birds produced only one egg at a time until they could fly, and gradually evolved to have only one fallopian tube. Some people think that this may have something to do with the origin of bird flight. Because birds need to reduce their own weight, they are stepped into only one fallopian tube.
