Antwort What’s the scariest extinct animal? Weitere Antworten – What is the biggest extinct animal ever
The world has a new contender for the heaviest animal that ever lived: a whale that swam the oceans some 38 million years ago and likely weighed almost 400,000 pounds. Scientists described the newly discovered extinct species, named Perucetus colossus, in a paper published Wednesday in the journal Nature.Many of the more famous prehistoric beasts gained notoriety because there's something about them, be it the size of their teeth, that they're covered in spikes, or their sheer size, that elicits a primeval sense of dread in our mammalian brains.Patagotitan mayorum, the Titanosaur. Patagotitan mayorum may have been the world's largest terrestrial animal of all time, based on size estimates made after considering a haul of fossilized bones attributed to the species. The collection included a femur (thighbone) that measured 2.4 meters (8 feet) from end to end.
Why were prehistoric animals so big : Being big had many benefits. The sheer size of titanosaurs and other large sauropods helped to protect them from predators. They could also eat food that was out of reach to other animals. In times of famine or drought, they could survive for a while thanks to the fat and water stored in their bodies.

Why did animals go extinct 10,000 years ago : At the end of the last ice age, 10,000 years ago, many North American animals went extinct, including mammoths, mastodons, and glyptodonts. While climate changes were a factor, paleontologists have evidence that overhunting by humans was also to blame.
North American short-faced bear
Bigger than any bear alive today, it stood 4m tall, weighed up to a tonne, and could bring down bison. Arctodus, or the North American short-faced bear, is an extinct bear genus that inhabited North America from the latest Pliocene to the Holocene epoch, from ~2.5 Mya until 10,000 years ago.
mosquitos
The ultimate example of a very small animal with a very big impact. In terms of the number of humans killed every year, mosquitos by far hold the record, being responsible for between 725,000 and 1,000,000 deaths annually.
What is the smallest extinct animal
Batodonoides vanhouteni
The smallest mammal that ever lived could be sitting right on your shoulder and you would hardly know it. Batodonoides vanhouteni, which lived about 50 million years ago in what is now Wyoming, was so small that it could climb up a pencil–and it weighed as little as a dollar bill.Big dinosaurs would perhaps only persist in protected reserves, such as national parks and wildlife refuges – modern-day equivalents of Jurassic Park. Smaller dinosaurs that infringed on crops or livestock would probably be hunted as 'nuisance' animals, as wolves and dingoes are today, adds Arbour.There is nothing about today's world that would be fatal to them. With that said, the major difference between the world of dinosaurs and today is that our modern Earth is considerably colder, with ice caps at the poles.
After the dinosaurs died out, nearly 65 million years passed before people appeared on Earth. However, small mammals (including shrew-sized primates) were alive at the time of the dinosaurs.
What is the rarest animal : The vaquita
The vaquita is the rarest animal in the world and the rarest marine mammal. These porpoises swim in the Gulf of California and were only discovered in 1958, according to the World Wildlife Fund.
How many tigers are left : 4,500 tigers
There are only approximately around 4,500 tigers left in the wild, according to the WWF, although some estimates put the number even lower. The most immediate threat to wild tigers is poaching, although some countries have limited resources for protecting areas where tigers live.
Is dodo really extinct
ExtinctDodo / Extinction status
The dodo was extinct by 1681, the Réunion solitaire by 1746, and the Rodrigues solitaire by about 1790. The dodo is frequently cited as one of the most well-known examples of human-induced extinction and also serves as a symbol of obsolescence with respect to human technological progress. (Read E.O.
Global warming is projected to commit over one-third of the Earth's animal and plant species to extinction by 2050 if current greenhouse gas emissions trajectories continue — a catastrophic loss that would irreversibly reduce biodiversity and alter both ecosystems and human societies across the globe.polar bears
Grizzly and polar bears are the most dangerous, but Eurasian brown bears and American black bears have also been known to attack humans. Some species depredate livestock on occasion, and some bears, such as Asiatic and American black bears, may destroy fruit or other crops, especially corn.
Which animal does not exist anymore : 1. Sabre-toothed Cat. Often called Sabre-toothed Tigers or Sabre-toothed Lions, they existed 55 million to 11,700 years ago. Sabre-tooth Cats were carnivores named for the elongated bladelike canine teeth, which in some species were up to 50cm long.
