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. sources: https://en.wikipedia.org/wiki/Phorusrhacidae htt...

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...
