Giant Terror Birds-apex predators after dinosaurs

Phorusrhacidaeare an extinct family of large carnivorous flightless birds also known asTerror Birds were the apex predators of the South America during the Cenozoic era. They ranged in height from 1 to 3 meters and weighted up to 350 kilos making them one of the largest birds that has ever existed. They all were carnivoures but were very diverse and occupied many different predatory niches. There is a theory that these birds became extinct as a result of the rise of Central America, which allowed predators from North America to occupy the niche of Phorusrhacidae and outcompeted them. Now this theory is unpopular. Terror Birds went extinct around the time when the continents joined together but large carnivores crossover much later also in North America lived group of large flightless carnivorous birds that coexisted with  mammal carnivores. For now we don,t know why and how Terror Birds disappeard.

    If they didn't in act fly, they didn't have much advantage over other animals feeding on the same food and hunting the same animals.

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...
