Heyuan has the resounding business card of "The Wizard of Oz", but few people know that there is another place that is more attractive, shocking and valuable, and that is the honor of "the hometown of dinosaurs in China" which enjoys a good reputation overseas.

The source is "the hometown of dinosaurs in China", which is the main producing area and collection place of dinosaur eggs in the world. Since16,000 dinosaur eggs were first discovered in Heyuan on March 6, 1996, more than 6000 dinosaur eggs/kloc-0 have been rescued and excavated in Heyuan. At the same time, dinosaur bone fossils and dinosaur footprint fossils have also been found in Heyuan, making Heyuan a rare dinosaur site in the world that integrates dinosaur eggs, dinosaur bones and dinosaur footprint fossils.
Heyuan Dinosaur Museum, located in Guifeng Park, Binjiang Avenue, Heyuan City, has continuously increased its collection since Heyuan City won the Guinness World Record with 10008 dinosaur eggs on October 29th, 2005. At present, the collection of "dinosaur eggs" ranks first in the world, reaching more than twice the collection in other parts of the world. Heyuan Dinosaur Museum is also the first national museum awarded directly by Chinese Academy of Sciences in Guangdong prefecture-level cities.
Heyuan dinosaur museum
Walking into the museum, a large sauropod dinosaur skeleton with a length of 20 meters and a height of 8 meters is displayed in the museum, surrounded by several dinosaur models such as pterosaur and egg stealing dragon. One of them is a simulated Tyrannosaurus Rex controlled by sound and electricity, shaking its hair and making a hissing sound. It is magnificent and lifelike, which makes people suspect that it broke into Jurassic Park hundreds of millions of years ago.
The exhibition is mainly divided into three parts: dinosaur delivery room, dinosaur footprint and dinosaur hometown. More than 65,438+07,000 dinosaur eggs of different sizes, shapes and types, as well as a number of individual dinosaur bone fossils and dinosaur footprint fossil models are exhibited in the museum. It is a rare dinosaur museum integrating dinosaur eggs, dinosaur bones and dinosaur footprints, which embodies unique dinosaur fossil resources.
Stepping into the first exhibition hall, there are a bunch of round dinosaur eggs in the window, which makes people feel shocked for the first time. It turns out that as early as a decade ago, Heyuan won the Guinness World Record with more than 10,000 dinosaur eggs. With the passage of time and the continuous discovery of dinosaur eggs in Heyuan, more than 17000 dinosaur eggs are displayed in this window.
Dinosaur eggs found in Heyuan are known 1995 12 16. After school, several children were playing on the construction site flattened by bulldozers near the school. They found some protruding spheres on the surface of stones, like dinosaur eggs mentioned in dinosaur warrior, so they told the father of one of the children. After on-site investigation by two experts from the Provincial Institute of Cultural Relics and Archaeology, it is judged that this is. In this way, a world-class secret was discovered in the child's play.
Dinosaur eggs are mainly round, but they are also large and small. The smallest one, with a diameter of only 3.5cm, is the smallest dinosaur egg unearthed so far in Heyuan City and the smallest dinosaur egg found and recorded in the world at present.
Some dinosaur eggs have turned into crystals, as transparent as crystals, which are unique to Heyuan and rare in the world. So far, it has not been found anywhere else, and how to form crystal dinosaur eggs is also a mystery.
It turns out that dinosaur eggs are not round. Some eggs are different according to their types. These eggs are oval and rectangular fossils.
The dinosaur footprint fossils found in Heyuan are large and clear, which shows that they are huge and powerful.
Footprints are similar in shape but different in size. The preservation of these footprints is the result of being covered by deposited sediments during the crustal movement.
Looking at some shocking bones and debris. Hard tissues such as dinosaur bones (including teeth) are deposited in sediments and isolated from oxygen. After tens of millions or even hundreds of millions of years of deposition, bones are completely mineralized and preserved.
The formation of dinosaur fossils is a complicated and long process. The fossilization process began when dinosaurs died and were soon covered with sediments or underwater sediments. These deposits contain fine particles, which will form a soft covering on the surface of the corpse. This kind of "blanket" can protect animal carcasses from scavengers, and can also isolate oxygen and inhibit the decomposition of microorganisms. After hundreds of millions of years, the bones are still intact, which makes people think deeply about the demise of the earth's dominant dinosaur hundreds of millions of years ago.

The death and extinction of dinosaurs are closely related to the changes of the earth for hundreds of millions of years, and the dinosaur era is also extremely far away from us; Without the help of fossils, we would know nothing about the mysterious dinosaur species. The numerous fossil collections in the museum prove that Heyuan has been a treasure house for biological reproduction since ancient times, and also warn us to cherish and care for the earth environment on which our human beings depend.
