Weifang created "East Asian Cultural Capital" | The little secret of dinosaur eggs

"East Asian Capital" is an important platform for international cultural exchanges and cooperation. The creation of the "East Asian Capital" is of positive significance for promoting urban cultural construction, enhancing cultural exchanges and cooperation, and promoting the development of world cultural diversity. Weifang has a long history and profound cultural heritage. It is the only candidate city in Shandong that has successfully selected the "East Asian Cultural Capital" in 2023. In order to help the creation of the "East Asian Cultural Capital" and improve the influence and communication of dinosaurs in the city, the cities rely on rich dinosaur cultural tourism resources, and use pictures and text to show tourists to show the small secrets of dinosaur eggs.

Dinosaur egg fossil is a reproductive product that can be passed on by dinosaur animals. Dinosaur egg fossil is a very precious paleomantic fossil. It was first discovered in 1869 in 1869 in the Baiji Period of Provence, southern France. The many dinosaur egg fossils found in the world have a variety of forms and diverse forms. The smallest is only 3 cm large, and the large egg length is about 50 centimeters long. The shape of egg fossils is usually round, oval, oval and olive. Whenever we see dinosaur eggs, we have a problem in our minds: How does egg fossil form? What kind of dinosaur is produced? This most often questioned question is actually the most difficult question.

When it comes to the problem of how fossils are formed, in order to facilitate understanding, we often raise the example of marinated salted duck eggs. The duck egg itself is not salty, soak the duck eggs in salt water, marinate for a few weeks. Because the salt molecules entered the duck egg through the infiltration effect, the duck eggs became salty. The formation of fossils is extremely similar to this. The remains or relics of paleontology are buried underground, forming fossils under the infiltration of inorganic objects rich in the ground underground. Dinosaur eggs are sleeping all year round, and "salty dinosaur eggs" have been marinated so long. Organic objects such as yolk and oval in eggs are replaced and replaced by inorganic objects. The liquid has been completely lost. shape. Due to the age, the standard reference cannot be determined, so it is difficult to determine which type of dinosaurs produced by the shape.

Some friends will question here, aren't there dinosaur eggs containing embryos? Since there are embryos, you can not know which dinosaur egg is! Indeed, it is possible to know which dinosaur egg produces by studying dinosaur eggs containing embryo. Due to the small number of dinosaur eggs found around the world, the calcium shells of eggs are generally seen. It is rarely found that the eggs with some kind of dinosaur embryo fossil are found. Therefore, the amount of dinosaur embryo eggs is very rare The average proportion of embryos in dinosaur eggs is not more than one in 10,000, and the dinosaur embryo, dinosaur larvae, and dinosaurs are also very different. It is inevitable that it cannot be divided during actual identification. Therefore, for a long time, the research on dinosaur egg fossils has not made important progress.

So, how to classify dinosaur eggs? This problem also plagues many paleontologists. In the early stage of the research of dinosaur eggs, it was classified according to the shape of the dinosaur egg fossil and the decoration of the egg shell appearance. The dinosaur eggs were roughly divided into plant food dinosaur eggs and carnivorous dinosaur eggs.

As more dinosaur egg fossils are found and new technical means are applied to the study of dinosaur egg fossils, the classification methods are becoming more and more comprehensive. We believe that paleontologists will solve more secrets about dinosaur eggs for us in the future.
