A Texas biotech just made history — hatching 26 healthy chicks from fully artificial eggs with no shell and no hen. Colossal Biosciences used 3D-printed structures and silicone membranes to pull it off. #ColossalBiosciences #DeExtinction #GiantMoa #ArtificialEgg #Biotech #ScienceNews #ExtinctAnimals #BiotechBreakthrough

Long after the dinosaurs vanished, Africa became a stage for some of the most powerful mammalian predators to ever exist. These were not just hunters. They were apex rulers that shaped entire ecosystems with strength, intelligence, and survival instincts. One of the most formidable was Megistotherium, a giant member of the extinct hyaenodonts that lived around 23 million years ago during the Miocene. With a skull over a metre long and an estimated body weight that may have exceeded 500 kilograms, it was among the largest land carnivorous mammals ever discovered. Its crushing jaws were built for bone, allowing it to dominate prey and scavenge with ease. Another terrifying predator was Hyainailouros, a close relative of Megistotherium. This animal stretched several metres in length and combined power with surprising mobility. It likely hunted large herbivores, using ambush and strength rather than speed alone. These hyaenodonts were not related to modern hyenas, despite the similarity in name. They represent a completely different evolutionary path that eventually disappeared. Africa also hosted early relatives of modern carnivores. Dinofelis, often called a false sabre toothed cat, roamed parts of Africa during the Pliocene. It had elongated canine teeth and a muscular build, making it a specialised predator capable of taking down sizeable prey. Later, true sabre toothed cats such as Megantereon appeared, refining these deadly adaptations even further. What makes these predators fascinating is how they reflect a period of evolutionary experimentation. After the extinction of the dinosaurs, mammals rapidly diversified, filling ecological roles once held by reptiles. In Africa, this led to a mix of ancient lineages like hyaenodonts and more modern carnivores competing for dominance. Over time, true carnivorans such as big cats and hyenas outcompeted many of these earlier predators. Changing climates and shifting environments also played a role in their decline. Yet, for millions of years, these giants stood at the top of the food chain, shaping the evolution of the animals around them. Here is a strange and intriguing fact. Some extinct predators like Megistotherium had teeth so robust that they could crush bone more efficiently than many modern carnivores, leaving behind fossilised bite marks that still puzzle scientists today. #ThePreHistoricWorld #paleontology #dinosaurs #jurassicworld #facts #prehistoric #africa #extinctanimals #fossils #ancientlife #earthhistory #science #animallife
