About 350 kilograms. The better known fibulasaurus weighs about 200 kilograms. Both were extinct by the time other large land animals evolved.
Eryops, an extinct amphibian from the Permian period, likely ate a variety of prey such as fish, insects, and small reptiles. Its large size suggests it was a top predator in its environment, hunting and feeding on smaller animals.
The description is consistent with Neanderthals, an extinct ancient human species. They lived alongside Homo sapiens and were known for their advanced tool-making skills, hunting large animals, wearing clothing, and displaying care for their sick and elderly. The exact reason for their extinction remains debated among scientists, with factors such as competition with other human species or environmental changes being proposed.
The great auk was a flightless bird that became extinct in the mid-19th century. They were large seabirds that primarily inhabited the North Atlantic. Great auks were known for their distinctive appearance, with black and white plumage and a large, robust body.
No one knows for sure how the dinosaurs went extinct. However, some of the theories are a dramatic climate change, or a large meteorite impact.
The large rodents became extinct due to evolution. This can happen to many different types of animals not just rodents.
Saber toothed cats (tigers) became extinct 11,000 years ago. Food sources were large animals such as elephants, rhinos and colossal herbivores of the era
The heat was drying up the water so animals could no survive .
The 12 animals that people should be glad are extinct are;giant crocodiles, 3 ft long scorpions, extremely large millipedes, spiders that sting, extremely large sharks, a hybrid scorpion and millipede, large piranhas, snakes larger than anaconda, large dragonfly, and prawns with teeth.
They hunted large animals, like horse, bison, mammoth, deer, aurochs (extinct wild cattle), etc.
All of their prey (large mammals) had vanished and had been replaced by smaller faster mammals like deer. The saber tooth cats were specialised in bringing down large animals and were not long distance runners so they found it very hard to catch the fast prey. They could not get enough food and became extinct :)
Scientists believe saber-toothed cats became extinct due to a combination of factors, including climate change and the decline of their prey. As the Ice Age ended, changing environments reduced the availability of large herbivores like mammoths and bison, which were crucial for their survival. Additionally, increased competition from other predators may have further contributed to their demise. These factors combined likely led to the decline of saber-toothed cats around 10,000 years ago.
The primary prey of saber toothed tigers were big game animals. They would have hunted deer, bison, camelops (an extinct species of North American camel), and even mammoths and giant ground sloths. At the end of the ice age, many of these large prey animals that the saber toothed cat depended on died out, and the saber toothed cat became extinct.
At the time of the dinosaurs, most large animals were reptiles and the dominant trees were conifers. Today, most large reptiles have been long extinct, and most large animals are mammals. The dominant plants are now flowering plants.
Megafauna means large animals. Sometimes, it is used to refer to the unusually large animals of the last ice age, such as mammoths. Sometimes, it is used to refer to large, extinct animals, such as the short-faced bear or the sabre-toothed cat. Sometimes, it is used to refer to dinosaurs. Sometimes, it is used to refer to large, modern animals, such as polar bears and hippopotami.
Nobody knows how any dinosaurs became extinct but the most likely explanation is that a 10Mile big meteorite smacked into the Earth
Nobody is certain why the saber toothed cats died out. They probably became extinct, however, because many of the large prey animals that saber toothed cats depended on died out. Theories for why this happened include climate change, overhunting by humans, and human induced diseases.
