![]() Quinkana has no surviving relatives, but it shares one trait with Theropod dinosaurs: teeth patterns. Quinkana first originated around 24 million years ago and died out approximately 40,000 years ago. Quinkana was one of Australia’s most potent territorial carnivores at the time, second only to Megalania. Over time, Quinkana increased in size from 2m to 6m long and was a quick predator, and became one of the dominant species by the Pleistocene. These colossal wild cats preyed on bison, antelope, and horses in the woods of North, South, and Central America. The Smilodon acquired its name from the Greek words “blade” and “tooth,” which really is appropriate given that they had large, curving canines that could reach 28 cm in length. Smilidon fatalis, Smilodon gracilis, and Smilodon populator are the three varieties of the Smilodon. Smilodon was a huge mammal that measured 160 to 280 kg (350-620 lbs), around the exact dimensions of lions and Siberian tigers. These cats with blade-like teeth have expanded into various groups over the last 10 million years, with the Smilodon being one of them. ![]() These ferocious felines, on the other hand, were nothing like the fuzzy bunnies you find on the comfy sofa. Saber-toothed cats roamed the globe for 42 million years until they disappeared approximately 10,000 years ago. Smilodon | Image Credit – Wikimedia Commons Their tentacles are shrouded with suckers that have powerful, jagged hooks that they use to capture prey and combat predators. They feed on small and large fish, including Patagonian toothfish and other sea creatures. The colossal squid is an extensively large deep-sea carnivore, nearing cumulative body and tentacle sizes of up to 46 feet and weights of around 1100 pounds.Īll of the largest individuals are female, as with many large mammals. It is hard to define the biology and ecology of this kind of rare organism, even something as huge as the colossal squid, with limited study prospects. It is not just the largest invertebrate on the planet, but it also has the world’s most prominent eyes compared to any animal, perhaps larger than those belonging to the majestic whales. Humankind’s understanding of the colossal squid is focused on limited samples collected in the deep-sea fishing industry and mandibles discovered in the abdomens of these organisms, such as their most notable predator, the sperm whale. The colossal squid is a humongous squid that dwells in the ocean depths around Antarctica and holds numerous global benchmarks. Into The Deep: Giant Squid Captured On Video | Video Credit – CBS Miami As for the newly discovered titanosaur fossil, more research is necessary to understand to guesstimate its exact size because some of the fossil’s bones have yet to be revealed. These size projections are determined by the size of the unearthed bone fragments. ![]() Patagotitan mayorum, for those who are unsure, is currently thought to be the world’s largest land-based animal from history to date. Titanosaurs are massive sauropods that have overshadowed the South American territories until the Cretaceous Paleogene evolutionary divergence, the asteroid strike that annihilated the vast bulk of life on Earth.Įxperts claim the remnant is one of the largest sauropods ever discovered, presumably surpassing Patagotitan in dimensions based on the study of the fossil. Sauropods were the dinosaurs featured in the Jurassic Park film series, with their incredibly long necks, tails, and pillar-like lower body. Per this concept, the dinosaur was also the largest creature on land that ever survived. Scientific researchers in Argentina have found a unique collection of bones that are now thought to have belonged to the biggest dinosaur that ever roamed the planet.
