Perucetus-the heaviest animal to ever exist

In 2018 bones of the perucetus were discovered in Peru and made it probably the heaviest animal to ever exist. This gigantic mammal has massive bones which aren't result of the disease and lived about 40 million years ago. To determine mass scientists used two paterns: one assuming the avarege skeletal fraction of adult manatees which are the living marine mammales with the strongest bone mass increase and the minimum skeletal volume mass and second using the living whale's lowest skeletal fraction and the maximum skeleton volume. From these two estimates, it could have weighed from 85 to 340 tons, to compare biggest whale weights 190 tons. Still we don't have the rest of the skeleton so we can only assuming perucetus' mass. Probably this thick bones were helping the animal control it,s buoyancy like with living manatees and dugongs. It mean that perucetus was living in the shallower parts of the ocean than most whales today. Massive bones could have restricted movements so it couldn't go anywhere fast.

    It would be good to know when it lived and what kind of animal it was - a mammal, a fish?

Quetzalcoatlus-the biggest flying animal to ever exist

Obraz
With a 11 to 12-m wingspan, Quetzalcoatlus is the largest flying organism ever known. This gigantic pterosaurs lived around 70 million years ago, probably in an environment inhabited also by the Tyrannosaurus and Torosaurus. Over the years belives, beliefs about how it flew and how it hunted changed. Latest studies says that Quetzalcoatlus was flying occasionly and only for short distances but it was a strong flyer when it did fly. It would probably have used its powerful hind legs to launch as high as 2.4 m when taking off. The most accepted hypothesis is that it lived like a stork and that it would hunt small prey like mammals, lizards and possibly small dinosaurs on land while also utilizing small streams and pounds to catch fish and crustaceans. Because of its size and flight capability it probably didn't have to worry about predators too often.  sources: https://www.google.com/search?q=quetzalcoatlus+compared+to+a+human&tbm=isch&ved=2ahUKEwiI3crl-_CBAxVEgosKH...

What happend to the largest ape to ever exist?

Obraz
Gigantopithecus was the largest ape that ever lived. It stood as high as 3 meters, weighed up to 500 kilograms and lived in the tropical forests of southern China for 6 to 9 million years. It probably didn't stray into the open like modern gorillas and was a fruit-eater. Due to the cooling of the climate forested areas turned into savanna landscapes. Somehow Gigantopithecus managed to survive the first few glacial periods but 100,000 years ago, at the beginning of the last of the Pleistocene ice ages, it went extinct.   There was simply an insufficient food supply for the giant ape, which probably had massive needs.  sources: https://www.nationalgeographic.com/science/article/160106-science-evolution-apes-giant https://www.google.com/search?sca_esv=580610545&sxsrf=AM9HkKkyvyVNt3QthAe8yLHimHj9grDtHg:1699477129548&q=gigantopithecus&tbm=isch&source=lnms&sa=X&ved=2ahUKEwjC9vDUpbWCAxUPPhAIHSIRCrwQ0pQJegQIDRAB&biw=1920&bih=923...

Ediacaran fauna-first animals

Obraz
Named for the Ediacara Hills of South Australia, in which they were discovered in 1946, were the first animals, despite sponges, made up of more than one type of cell, that required atmospheric oxygen for their growth. Almost all of these fossils are dated between 575 and 542 million years ago. These creatures had wide variety of shapes and sizes from circular discs reaching 20 cm to frond-shaped that can be as long as 1 meter. Some of them were similar to today's jellyfishes, soft corals and seeweed but some were unlike to the organisms known today. At the begining of the Cambrian explosion they disappear almost simultaneously probably becouse of the emergence of Cambrian predator animals. Ediacaran fauna's relationships with the rest of extant and extinct animals has not been possible to firmly establish, so they may not be connected to the rest of the organisms on Earth. sources:  https://www.google.com/search?q=ediakar&tbm=isch&hl=pl&bih=839&biw=1...
