The lifespan of a dinosaur The length of an animal's lifespan is often associated with its growth pattern. Animals with unrestricted growth have a longer lifespan than animals with limited growth. If we apply the unrestricted growth patterns of living animals to the study of dinosaurs, the time required for some groups of dinosaurs to hatch from eggs to adulthood is as follows:
Protoceratosaurs took 26-38 years, medium-sized sauropods 82-118 years, and giant sauropods, such as Brachiosaurus, took more than 100 years. Then, if the dinosaur could live for the same length of time after growing into an adult, Brachiosaurus could also live for about 300 years. Another factor that affects how fast or slow an animal grows is their metabolism.
On average, hot-blooded vertebrates grow at least 10 times faster than cold-blooded animals. The faster it grows, the shorter the lifespan; The slower the growth, the longer the lifespan. What kind of metabolism did dinosaurs have?
Are they hot-blooded or cold-blooded? This is a key to our correct estimation of the lifespan of dinosaurs. There is a lot of evidence that many dinosaur taxa were hot-blooded animals.
If this is true, the lifespan of a dinosaur can be calculated using the growth patterns of living hot-blooded vertebrates. If it is a hot-blooded dinosaur, it can live for decades to more than 100 years. In short, we don't know exactly how long dinosaurs lived for long ago.
Some paleontologists, after studying the growth rings of some dinosaur bones, found that these dinosaurs were about 120 years old when they died. Therefore, it is believed that dinosaurs may have lived longer, i.e. they may have lived to be 100-200 years old.

How long did dinosaurs live.
-
Between about 100 200 years.
Some paleontologists have found that the average age of death of dinosaurs was about 120 years old. But there's a lot of evidence that they don't die of natural aging.
Many dinosaurs died unexpectedly, or were eaten by other dinosaurs, or died in natural disasters, etc. Therefore, according to reasoning, dinosaurs should never live longer than 120 years.
When dinosaurs get older, just like people, they are inflexible, sick, and physically exhausted, so they lose the ability to protect themselves, and in the competitive environment of the jungle, this can easily become the belly of carnivorous dinosaurs, that is, dinosaurs in the Mesozoic without "old-age security", it is difficult to live to the maximum age they should live.
It can be seen that the lifespan of dinosaurs should be relatively long, about 100 200 years, and it is possible to exceed 200 years. Moreover, the chance of survival is not unrelated to the size of the body, like those huge dinosaurs, such as Zhenlong, Diplodocus and Brontosaurus, it is probably not a problem to live for more than 200 years. Because the phytosaurus was taller than the carnivorous dragon, it also lived longer than the carnivorous dragon.
Dinosaurs can be divided into avian and non-avian dinosaurs.
Among them, non-avian dinosaurs lived only in the Mesozoic era (Triassic, Jurassic and Cretaceous) and were all extinct 65 million years ago. We often say that birds are the only dinosaurs that have survived to this day, but not all birds have survived. The common ancestor of our current birds is called the Neornithes.
At that time, there were actually more enantiornithes and hesperornithiformes.
The subclass of birds, which were fortunate enough to survive, faced with an unprecedented opportunity after the extinction of the dinosaurs, quickly filled these ecological niches by changing their form, so there was a very spectacular scene in the history of evolution. Just 20 million years later, the main branches of living birds have been largely formed.

Dinosaurs lived between 75 and 300 years.
Some dinosaurs lived for 300 years, and paleontologists estimate that large dinosaurs lived between 75 and 300 years. However, this estimate is based on the fact that dinosaurs were cold-blooded. If they are warm-blooded, then the lifespan will be shorter, but they will generally live for at least 75 years.
This is based on the fact that a larger brontosaurus, a warm-blooded animal, could have been "cooked" due to its large size, which made it difficult for it to survive. As a result, scientists generally believe that they are cold-blooded and have a long lifespan.

The lifespan of dinosaurs was between 75 and 300 years. Paleontologists estimate that dinosaurs lived around 75 to 300 years, and if dinosaurs were cold-blooded, then they lived longer. If the dinosaurs were warm-blooded, then their lifespan would be relatively short, but they generally lived for at least 75 years.
Dinosaur. Dinosaurs are longer than blue whales. The Argentinosaurus lived between 97 million and 94 million years ago and weighed 70 tons, 40 meters long and tall meters, while the blue whale weighed about 200 tons and was 30 meters long.
Recent studies have found that many dinosaurs had feathers, but they barely flew and lived mainly in woodlands or open areas on lakeshore plains (or coastal plains).
Dinosaurs are a group of reptiles that appeared during the Mesozoic era (Triassic, Jurassic and Cretaceous), with muscular limbs, long tails and large bodies.
-
The dinosaur was 120 years old when it died. There is no evidence that they died of old age after a lifetime of recuperation. Many dinosaurs died in accidents, and elderly, juvenile, and disabled dinosaurs were the main predators of carnivores.
Therefore, 120 years old is not the age of high life for dinosaurs. Excluding the factor of unnatural death, it should not be a problem for dinosaurs to live to 100 200 years. They are the longest-lived animals other than turtles.
Extended information: 1. Dinosaur Introduction:
Dinosaurs (English name: dinosaur) are a group of reptiles that appeared during the Mesozoic era (Triassic, Jurassic and Cretaceous), with sturdy limbs, long tails and large bodies that are portrayed by most dinosaurs. They mainly inhabit woodlands or open areas on lakeshore plains (or coastal plains).
In 1841, when British scientist Richard Owen studied several fossilized lizard bones, he believed that they were left by some prehistoric animal and named them dinosaurs, which means "terrifying lizards".
The dinosaurs suddenly disappeared at the end of the Cretaceous period 65 million years ago, becoming a mystery in the history of the evolution of life on Earth, which is still unsolved. All of the earth's past creatures are recorded in fossils. In the strata of the Mesozoic era, many dinosaur fossils have been found.
A large number of bones can be seen in a variety of shapes. However, in the Cenozoic strata that followed, there were no fossils of non-avian dinosaurs at all, which suggests that non-avian dinosaurs became extinct together during the Mesozoic Era, and that only birds remain today, and most scientists agree that "birds belong to dinosaurs".
There are many types of dinosaurs, and their body shape and habits also vary greatly, with the largest fragile dinosaur being more than 50 meters long, while the smallest hummingbird may be less than 10 centimeters. In terms of eating habits, there are docile herbivores and ferocious meat eaters, as well as omnivorous dinosaurs that eat both meat and vegetables.
2. Appearance characteristics:
The bones of dinosaurs had some evolutionary adaptations that allowed them to be distinguished from the original archosaur ancestors. In later dinosaurs, these features underwent more evolutionary changes. The common delineation of dinosaurs includes:
Posterior frontal bone is missing. The humerus has a low triangular crest attached to the sternoclavicular deltoid muscle, which is about 1 3 to 1 2 the length of the humerus. There is a protruding mass in the posterior part of the intestinal bone, and the acetabulum is perforated.
The tibia has a broad terminal margin with a posterior flange. The talus has a distinct superior process that fits the tibia.
Most dinosaurs were much smaller than large sauropods. The available evidence suggests that the average size of dinosaurs varied throughout the Triassic, Early Jurassic, Late Jurassic, and Cretaceous periods. Most theropods weighed between 100 and 1,000 kilograms, while predatory carnivores in the Holocene were mostly between 10 and 100 kilograms.
Dinosaur weight estimates are mostly between 1 and 10 metric tons. According to a study by the National Museum of Natural History in London, the average weight of dinosaurs was about 100 kilograms, while the average weight of Cenozoic mammals was between 2 and 5 kilograms.

Generally speaking, the bigger the dinosaur, the longer the lifespan, small dinosaurs like the Wounded Tooth only lasted four years, and the Rex Tyrannosaurus could live for thirty to forty years. Communication Microdragon can also live for about forty-five years.
-
Small dinosaurs such as the Romandichosaurus could live for 3 years; A dinosaur as big as a tyrannosaurus rex grew like crazy and could live for about 30 to 40 years; Giant dinosaurs like Brachiosaurus lived for about 100,110 years.
-
You can live up to 120 years. The life span is relatively long.
-
Baby dinosaurs can live 12 years old, medium dinosaurs can live 36 years, and giant dinosaurs can live 123 years.
-
The average lifespan of a dinosaur is 100 years to 300 years.

One or two years should be fine, but now, where is it?
The life span of rabbits is generally 5-12 years, during this period, rabbits gradually transition from prime to old age, and various organs of the body gradually age, gradually degenerate their functions, and finally die. According to records, the world's longest-lived rabbit is a DO from the United States, who lived for 17 years and 2 weeks. 5 to 15 years, depending on the breed of rabbit, generally large rabbits have a relatively longer lifespan. >>>More

On July 3, the results of the first phase of the excavation of dinosaur fossils in Henan Province held by the Provincial Department of Land and Resources were released, saying that the newly discovered fossils are about 100 million to 85 million years old, which belongs to the early Late Cretaceous. More than 30 dinosaur fossil sites have been found in Ruyang County, and more than 6 kinds of dinosaurs have been unearthed from 5 of them, among which "Luoyang Zhongyuan Dragon" is the only large nodular dragon ankylosaurus found in China at present, which has rewritten the saying of nodulosaurus in China. "Ruyang Yellow River Dragon" is a new species of sauropod dinosaurs, 18 meters long, about 6 meters high on the forelimbs, 3 meters wide at the shoulders, experts estimate that its weight is 60 tons, equivalent to 10 elephants, is the tallest and heaviest dinosaur found in Asia so far. >>>More
