Could early humans--specifically Neandertals--survive in the Mesozoic? Will their spears, usage of fire, and sociality be enough to keep them alive in a world dominated by carnivorous monsters and walking earthquakes? Late Jurassic North America was a brutal place, with searing heat, a lack of flowering plants, and plenty of reptilian superpredators to keep the humans occupied. Dinosaurs like Ceratosaurus, Allosaurus, Torvosaurus, and Saurophaganax were the apex predators of the Morrison Formation, and the giant herbivores like Camarasaurus, Brachiosaurus, Supersaurus, and Apatosaurus are much more difficult targets than the elephants that these Neanderthals were used to hunting. Will our hominid relatives thrive...or get eaten alive?

![Ultimate Predator: How T.rex Broke the Game
Who let the game devs do this? Cutting-edge paleontological studies explain the biological factors that made T.rex so successful and how it was able to outcompete all rivals. Tyrannosaurus rex was the biggest theropod known to science. T.rex is famous for its bone-crushing bite, incredible senses, and physical power, but it may have also been as intelligent as a primate. T.rex was so OP because of a combination of its keen senses, a bite force that could crush a car, a muscular and powerful body, high agility compared to other theropods, and intelligence that ranged from comparable to crocodiles to primates. Naming T.rex the Tyrant Lizard King was prophetic, as it seems that with every new study released T.rex only becomes more dangerous and majestic.

![The Size Limit of Spinosaurus
Recent discoveries about Spinosaurus, the sail-backed giant theropod, have changed our understanding of its ecology and lifestyle. Spinosaurus aegyptiacus was one of the largest predators of all time, and dominated the river systems of northern Africa during the Cretaceous Period. Here Vividen analyzes how big Spinosaurus could have gotten in life. What were the size limits of Spinosaurus? Was it bigger than T.rex? Was it, in fact, the biggest theropod?
