It is one of the largest land carnivores and the most famous carnivorous dinosaur in history. It is one of the latest dinosaurs, with a body length of11.5 ~14.7m (the maximum length along the bend15.3m).
The average hip height is 4.3 meters. The average height is 5 meters and the highest is 5.2 meters.
The average weight is 9 tons, the maximum weight is 14.86 tons and the head length is 1.2- 1.55 meters. The biting power ranks first among terrestrial creatures (the biting power can reach 4~20 tons), and it is also the strongest carnivorous dinosaur.
Tyrannosaurus rex lived in the Maastricht stage at the end of Cretaceous, about 68.5 million to 65.5 million years ago. It was one of the last non-avian dinosaurs before the Cretaceous-Tertiary extinction event. Fossils are distributed in North America, the United States and Canada. They are one of the latest extinct dinosaurs and the strongest carnivores known in the history of land.
The American Museum of Natural History displayed two giant space photos taken by the Hubble Space Telescope to commemorate the Hubble Space Telescope 15 birthday.
These two giant space photos show the spiral galaxy M5 1, and the other shows the eagle nebula with a strange shape. The dimensions of the two photos are 10x7 feet and 10x5 feet respectively. Mike Shara, director of the astrophysics department of the museum, who published space photos, participated in the development of the Hubble Space Telescope. He pointed out that it is the most meaningful way to celebrate the birthday of Hubble Space Telescope 15 to show the photos of the deepest part of the universe observed by Hubble Space Telescope so far.
Hubble Space Telescope was launched on1April 25th, 990. Its purpose is to observe and photograph space in Earth orbit outside the Earth's atmosphere, so as to reduce the distorted influence of the atmosphere on observation. Since 15, the Hubble Space Telescope has been orbiting the earth for about 3 billion miles. The pictures it takes are very clear and it is the most scientific equipment in human history. Since the Hubble Space Telescope was put into use, scientists have taken more than 700,000 images of various celestial bodies through it, including some photos of galaxies that existed tens of billions of years ago. On May 22nd, 2007, the famous American Museum of Natural History in new york previewed a special exhibition entitled "Mysterious Creations: Dragons, Unicorns and Mermaids". There is a 36-meter-long China Dragon Dance prop hanging above the exhibition area, which is very eye-catching.
The exhibition shows various images of dragons, unicorns and mermaids from different cultural backgrounds such as Asia, Europe, America and Africa through various models and cultural relics. Among them, the Dragon Exhibition Area is a large American natural history museum through dragon dance props, robes, shadow play and antiques. Located on the west side of Central Park in Manhattan, new york. Established in 1869. Covers an area of more than 70,000 square meters. There are 19 buildings and more than 50 exhibition halls. There are planetarium and library. There are more than 36 million pieces in the collection, with 42 exhibition halls, including dinosaur skeletons with a length of12m and a height of 5m, a blue whale model with a height of 94 feet, a 563-carat Indian sapphire star, and the world's largest meteorite weighing 3 1 ton. In addition, watch movies and materials related to nature in the natural IMAX giant screen cinema and planetarium.
This museum includes dinosaur fossils and exhibits related to animals, geography, humans and biology. In particular, exhibits showing the evolution of life on earth are difficult to distinguish from real life. Barosaurus made of real fossils, the model of 150 ton blue whale 1925 hunted off the southern coast of the United States, and the Indian canoe with a length of 19.5 meters are all must-see exhibits in this museum. The museum is a pioneer in exploring the wild and creating realistic models showing natural habitats and animal and plant life.
The museum has collected more than 30 million research specimens, and the collection of fossils and insects is one of the largest in the world. The dinosaur and mammal fossils on display are particularly impressive. The museum is engaged in anthropology, astronomy, entomology, herpetology, ichthyology, invertebrates, mammals, mineralogy, ornithology and vertebrate paleontology.
As of 201165438+February, the American Museum of Natural History has 3 million specimens and cultural relics. These collections were collected through various channels at different times.
According to Dr. Rex Worthy, some of the museum's early collections were donated by private individuals. After that, the international research team of the museum also brought back many collections for it. Others are purchased from small museums that cannot continue to operate for various reasons.
At present, only about 2% of the huge collections in the Natural History Museum are displayed to the public, and the rest are still used as research resources for museum scientists. However, with the completion of the ongoing digitization project of museum collections, the public is expected to see those collections that are deeply hidden behind the scenes.
Holding exhibitions is the most direct and intuitive way for museums to show their collections and scientists' research results to the public. The Natural History Museum has 45 fixed exhibition halls, of which 15 was newly built in 10.
In addition to these fixed pavilions, the museum also holds exhibitions on other topics from time to time, including animal exhibitions and ancient cultural relics exhibitions.
What is the dinosaur skeleton of the American Museum of Natural History? Tyrannosaurus Rex, also known as Tyrannosaurus Rex, is the largest of Tyrannosaurus Rex, and its name means cruel lizard king. It is one of the largest land carnivores and the most famous carnivorous dinosaur in history. It is one of the latest dinosaurs, with a body length of11.5 ~14.7m (the maximum length along the bend15.3m). The average hip height is 4.3 meters. The average height is 5 meters and the highest is 5.2 meters. The average weight is 9 tons, the maximum weight is 14.86 tons and the head length is 1.2- 1.55 meters. The biting power ranks first among terrestrial creatures (the biting power can reach 4~20 tons), and it is also the strongest carnivorous dinosaur.
Tyrannosaurus rex lived in the Maastricht stage at the end of Cretaceous, about 68.5 million to 65.5 million years ago. It was one of the last non-avian dinosaurs before the Cretaceous-Tertiary extinction event. Fossils are distributed in North America, the United States and Canada. They are one of the latest extinct dinosaurs and the strongest carnivores known in the history of land.
The British Museum of Natural History has about 40 million specimens of animals, plants, rocks and minerals from all over the world, including more than 7 million fossils of paleontology. There are 500,000 kinds of books in the library, and a large number of early natural research manuscripts and pictures are preserved. The whole museum has 20 large exhibition halls, including paleontology, minerals, plants, animals, ecology and human beings. The central hall is a modern life science exhibition hall, which introduces the knowledge of evolution and anthropology with three-dimensional landscape and showcase. The right-wing exhibition hall on 1 floor displays fossils of paleontology, including ichthyosaurs, plesiosaurs, 5-meter-high Tyrannosaurus Rex, tiny new jaw dragons, pterosaurs with a tail as long as 17 meters and complete archaeopteryx bones. The exhibition hall on the left displays modern animals, including marine animals, fish, birds and reptiles without cervical vertebrae. Among them, the display of birds is the best. On the left side of the second floor, mammals are displayed, among which the most wonderful ones are African savanna dwellers and Australian marsupials; On the right, minerals, rocks, precious stones and marble are displayed, and there is a special room to display meteorites. The third layer is the display of modern plants and fossil plants.
Who has all kinds and introductions of lions in the world? And the picture 1. North African lion (P. l. leo): Non-lions are also called Barbary lions.
Lions in North Africa have obviously different characteristics from other lions. Their skulls are thicker than those of other lion subspecies, and the posterior orbital spacing is particularly narrow. Interestingly, the skulls of North African lions are particularly similar to those of Asian lions, which seems to imply that the two subspecies are closely related.
In addition, the coat color of North African lions is darker than other subspecies, and the mane is long and strong. Unfortunately, this subspecies became extinct in 1925.
2. The Cape Lion (P. l. melanochaita) is extinct and is said to be the largest subspecies of lions. Originally distributed in Cape Province, Cape Province recorded that the last wild lion was killed in 1858, but pointed out that the last Cape lion was killed by a British general in 1865.
At present, London Museum of Natural History, Elizabeth Stuttgart National Museum of Natural History and Wiesbaden Museum in Germany have only one male horned lion and two female horned lions. The lion horn specimen from the Wiesbaden City Museum in Germany was collected 65,438+000 years ago. The measured results of this specimen are that the body length is 2.76 meters, the tail length is 0.82 meters, the skull is smooth and the snout is short.
3. Asian lion (P. l. persica), also known as Persian lion, most of its wild population has been extinct. In the past, it was distributed from northern Greece through southwest Asia to central India. Persian lions in Azerbaijan disappeared as early as 10 century, the last wild Persian lion in Turkey was extinct in 1870, and the last wild lion in Syria was found in 1920.
The Persian lion is obviously smaller than its African counterpart, and the largest measurement record is 2.9 meters long (from nose to tail). In order to distinguish lions in India and Central Asia, scholars named Indian lions Panthera Leo Goojeratensis Gujarat is Lions.
At present, there are about 250-300 animals in Gil Nature Reserve in Gujarat, the westernmost part of India. In fact, the wild lions in southern India disappeared as early as 1920. It is reported that these last wild lions in Asia are said to be descendants of Persian lions, which were introduced from Central Asia by India, not native to India.
Interestingly, there are usually no more than five lionesses in the lion group in Jill Nature Reserve, but in Africa, more than five lionesses are very common. Gujarat lions have shorter manes than their African counterparts, so their ears are always obvious.
4. The Angolan lion/Bleyenberghi Panthera Leo Bleyenberghi is accurately translated into brennerbeghi subspecies, and brennerbeghi should be a person's name. This subspecies is distributed in Katanga Plateau and Angola from southern Congo to north-central Zambia, so it is also called South Congo subspecies or Katanga subspecies or Angola subspecies.
5/6. North/Congo lion (P.L. Hollisteri/Azandica) Panthera Leo Hollisteri is a subspecies of Hollister and a name. According to a lot of data, this subspecies is Congo, and I don't know whether it is Congo (Brazzaville) or Congo (Kinshasa), but the latter has two subspecies. Congo (Kinshasa) was once called Zaire, so this subspecies should be distributed in Congo (Brazzaville) on the north bank of Congo River (Zaire River) to separate the two subspecies.
7. P.L. Verneyi Panthera Leo Verneyi is a species in Virginia, and Verney is also a name. The English name Kalahari subspecies is also called Namibia subspecies or Southwest Africa subspecies because it is mainly distributed in Kalahari National Park, that is, in Namibia.
8. The Kruger Lion/South African Lion (P. l. krugeri) is mainly distributed in transvaal province, South Africa, so it is also called Transvaal subspecies. It lives in Kruger National Park with a population of about 1400. The main threat of Kruger lions is the killing of herders. Local herdsmen think that lions coming out of the park are a great threat to people and livestock.
During the period of 1998-200 1, more than 100 Kruger lions crossed the park boundary, and one third of them were shot, mostly females. Another threat is disease. 1995, researchers found that 90% lions in the south of the park suffered from tuberculosis, and it was spreading to the north of the park.
This disease mainly occurs in the digestive system of lions. The reason is very simple, that is, people with tuberculosis are infected with domestic cattle, while domestic cattle are infected with bison, and lions get the disease after killing bison.
A sick lion is weak and usually dies within a few years. 9. The Marseille Lion (P. l. massaicus) Gee B. Schaller once wrote The Lion of the Serengeti (meaning "The Lion of the Serengeti"), which is a good book about the Marseille lion. At present, it is reported that the number of Marseille lions in Serengeti has increased from 2,000 to 3,500.
The type specimens of this subspecies are from Masai Mara National Park, mainly distributed in Uganda, Kenya and Tanzania. Every year, Masai lions follow wildebeests to migrate between Serengeti National Park in Tanzania and Masai Mara National Park in Kenya, and many zoologists will study them.
10. Roosevelt Lion/Ethiopian Lion (P.L. Roosevelt I) Panthera Leo Roosevelt subspecies, named Abyssinia subspecies in English, Abyssinia refers to Ethiopia. 1 1. Lions in Senegal are almost extinct now.
The former distribution areas are Kitamoto, Ghana, Senegal, Nigeria, western Sudan, Cameroon and Niger. At present, there are still lions in several wildlife reserves and national parks in northern Nigeria and Cameroon, and scholars are used to listing them as "-Panthera leo kamptzi".
12. Somali lion (P. l. somaliensis) is mainly distributed in Somalia. 13. Nubian lion/East African lion (P. l. nubica) Nubian is an ancient name of Sudan, and their size is slightly smaller than that of lions in southern Africa. In the past, the "Nile lion" in the ancient Nubian culture in the border area between Egypt and Sudan was this subspecies.
