Cultural relics in the Dalian Natural History Museum
There are nearly 200,000 specimens of various kinds, more than 6,000 precious specimens, and 264 first-class collections. The collection is characterized by marine biological specimens and fossil specimens of the "Rehe Biota", among which there are more than 20 types of marine animal specimens. The types and quantities are the largest among domestic natural history museums, including large cetaceans, dugongs, white-tip dolphins, giant pandas, and golden monkeys. , echidna, platypus, crested ibis, bird of paradise, hummingbird and the earliest insectivore Endotherium fossils, etc., are all precious specimens in the world. The black right whale is 17.1 meters long and weighs 66.7 tons. It is currently the largest black right whale specimen in Asia. The fin whale is 18.4 meters long and weighs 34.7 tons. It is the only fin whale specimen in China. The ancient lotus seeds were buried about 821 to 1251 years ago and can still germinate and bloom after being cultivated. The museum also preserves complete sets of insects from Taiwan Province and a large number of insect specimens from around the world, as well as rock and mineral specimens from Germany, Japan, North Korea, the Soviet Union and other countries. Among them, the orthoclase crystal family from the Korean Peninsula has large crystal clusters and beautiful crystal shapes, which are rare at home and abroad.
The basic display of the museum is divided into five parts: marine life, geology and minerals, the origin of life and the emergence of humans, animals and plants, with 4853 specimens on display. Among them, the display of marine life in the Yellow Sea and Bohai Sea highlights local characteristics. The display of large whale specimens ranks first in China and only a handful abroad. The museum also often holds various special exhibitions, such as: "Chinese Hairy People Picture Exhibition", "Eugenics, Preferential Education, Excellent Education", "French Natural History Exhibition", "World Insect Exhibition", "Antarctic Exhibition", " South China Sea Exhibition" etc.
The library has participated in the compilation of provincial, municipal and national fauna, flora and other books. The book "Chinese Hairy People" won the second prize for the National Outstanding Science and Technology Book in 1983; "Inspection on Snake Island" won the 1978 Provincial Major Scientific and Technological Achievement Award.
The library also often conducts academic exchanges with foreign countries. In September 1984, the Kitakyushu City Museum of Natural History in Japan was invited to exhibit "Insects of the World" there. In August 1986, the museum was invited to exhibit "Birds and Beasts of the Northeast" in Kitakyushu and Wuzuru City, Japan. Natural jadeite (Jadeite)
The main mineral of jadeite is jadeite, with a Mohs hardness of 6.5~7. It is dense and tough and is a precious jade raw material. The name Jade was originally the name of two birds in ancient China, namely Fei, a red-feathered bird; Cui, a green-feathered bird. Because the feathers of the jade bird are very beautiful, the ancients often used it to make jewelry and called it jade. Until the late Ming and early Qing dynasties, the term jade gradually referred to jade mainly composed of jadeite minerals.
Finished jadeite is divided into four categories in commerce and trade based on processing techniques: natural, improved, synthetic, and imitation.
Natural jadeite: a natural product without any artificial treatment, commonly known as A product.
Improving jadeite: After bleaching and filling treatment, jadeite can maintain its beautiful appearance for a short period of time. Such jadeite is commonly known as B goods; through dyeing, color dipping, curium color, coating and radiation color addition, the jadeite can be made more beautiful. Keeping the bright color for a short period of time, this kind of jade is commonly known as C goods.
Synthetic jadeite: refers to varieties that are very close to the chemical composition and mineral composition of natural jadeite formed in the laboratory through ingredients under a certain temperature and pressure environment.
Imitation jadeite: generally refers to some green or partially green other gemstones, single crystal minerals, artificial products and items similar in appearance to jadeite.
Zhuanghe Stone Aerolite
It fell in Zhuanghe, Dalian City in 1976. It is a chondrite meteorite.
Meteorites are meteoroids that fall from space to the earth. They can be divided into three categories: the first category is iron meteorites, whose main component is iron-nickel alloy, containing about 90% iron and having a large specific gravity. This type of meteorite accounts for 6% of the total; the second type is stony meteorite, which is more numerous, accounting for 92% of the total, and its composition is silicate, which accounts for 90%, followed by iron-nickel alloy; the third type is iron stone meteorite , iron, nickel and silicate account for half each. This type of meteorite is relatively small, accounting for only 2% of the total. In addition, our country also has glass meteorites called "Leigong Mo". They may not come directly from space, but are formed by large meteorites impacting the surface sandstone and cooling rapidly after melting. Meteorite specimens play an important role in inferring the chemical composition of the earth and exploring the evolution of celestial bodies.
Diamond
Diamond is known as the "hardest" and "king of gems" because it is super hard, wear-resistant, heat conductive, semiconductor and transparent. Due to its excellent physical properties such as infrared light, it is widely used in various industrial fields.
Diamonds that can be used to polish gemstones, called diamonds, are the most precious gemstones. Because of their extremely high dispersion, they were called "night pearls" in ancient times.
The diamond here is produced in the Wafangdian diamond mine in Dalian City and weighs 15.95 carats. The mine's proven reserves account for 54% of the country's total reserves, making it the largest diamond mine in Asia. The discovery of the Wafangzhuang diamond mine has made China's total diamond reserves rank 10th in the world. The full diamond produced by this mine is world-famous for its high quality and high gem-quality content. Its products enjoy a high reputation in the international diamond market. Diuridia montelii
Diuridia montelii is more primitive in evolution than other fossils of the family Diuridae.

The outermost chamber near the shell mouth is where it lives, which is called the "living chamber". The remaining chambers are filled with air. Called the "air chamber". Nautilus can make its body sink and float in the ocean by adjusting the air content in the air chamber.
Because of its heavy shell, Nautilus usually lives on the bottom of the deep sea. It crawls on the bottom of the sea with its tentacles. Sometimes it also uses a funnel to spray water to swim in the sea. Especially on calm nights after a storm, it likes to float in groups. On the surface of the sea, but soon back to the bottom of the sea, so live nautiluses are rarely seen.
