The biggest predator was likely a macropredatory icthyosaur! Ichthyotitan severnensis and the Aust Colossus were candidates for predators bigger than a blue whale or close to it. Prehistoric ocean predators existed on a different scale than modern oceans. Ichthyotitan is known from the Lilstock Monster and Blue Anchor specimens, and were likely bigger than most Otodus megalodon. The world's biggest predators weren't fully grown, either! The Aust Colossus very likely would have been bigger than a blue whale when at adult size, and based on morphological comparisons with other relatives could have been the biggest predator ever. In 2018, a team of scientists published an analysis of enormous jaw bones from the Late Triassic of the United Kingdom. These jaw bones were discovered across the UK: the Lilstock Monster specimen was found by Paul de la Salle and is now one of the specimens assigned to the new genus Ichthyotitan severnensis. The Ichthyotitan holotype is another more complete surangular that gives us more clues about the enormous animal’s life and body size. The Aust Cliff material, found decades earlier, had been mistaken for dinosaur limb bones due to its enormous size. The 2018 paper argued that these huge fragments both belonged to shastasaurid ichthyosaurs, which were the largest marine reptiles known. Two new studies expand our knowledge of these animals, confirming the ichthyosaur diagnosis and discovering that none of these whale-sized creatures were fully grown.

Saurophaganax maximus was the biggest theropod in the Jurassic Period, but remains relatively obscure despite being the biggest apex predator in North America besides Tyrannosaurus. New data indicates that not only was it a beast in the same league as the biggest megatheropods, but it was a sauropod-hunting grappler with powerful arms, claws, and other adaptations for taking down the giants of the Morrison Formation. This video analyzes Saurophaganax's life, ecology, and size in order to create the new authoritative guide to the animal. Saurophaganax may be a dark horse in the megatheropod race, but it might be bigger than popular giants like Carcharodontosaurus and Spinosaurus when it comes to the largest specimens of each species. Is Saurophaganax different from Allosaurus? Saurophaganax coexisted with other large predators like Torvosaurus and Allosaurus, and may have hunted huge sauropods like the Kenton Giants, Barosaurus, Brachiosaurus, Apatosaurus, and Diplodocus. Including the gigantic specimen Leviathan, Saurophaganax was the second-largest North American theropod, only behind Tyrannosaurus itself in terms of overall mass.
The source for the Saurophaganax specimens and measurements is DJ Sandy aka 7 Shots, who has been working with the animal for years and will be publishing a formal redescription soon. Measurements are not reproduced in this video in order to respect the Sam Noble Collection's social media guidelines.

It lived in Late Cretaceous North America and was one of the most formidable herbivores in its ecosystem at 5 to 8 tonnes as an adult. It lived alongside Tyrannosaurus rex, the most powerful theropod known to science. Media often portrays the battle between Triceratops and Tyrannosaurus as very one-sided, whether that be Triceratops easily repulsing the predator or Tyrannosaurus casually taking down the tank of an herbivore. What does the fossil record indicate about the combat that happened between Triceratops and Tyrannosaurus, and what do paleontologists have to say about it? This video includes a sneak peek at groundbreaking research on ceratopsian agility being done by graduate student Kyle Atkins-Weltman, along with input from theropod biomechanics expert Eric J.

Tyrannosaurus rex is the megatheropod with the largest sample size, which may lead to finding the biggest specimens. The gigantic Tyrannosaurus rex specimen E.D. Cope, “Copium rex,” may be the biggest Tyrannosaurus rex specimen yet described in the literature. This video takes measurements from paleontologists and uses them to calculate how big was the biggest Tyrannosaurus. E.D. Cope was likely bigger than Scotty, Sue, Trix, and almost any other theropod. With new estimates placing it at approximately 1500 kilograms heavier than even the dentary Giganotosaurus specimen.

Mega sauropods are the biggest dinosaurs ever by far. So out of the biggest sauropods ever, which mega sauropod claims the title of king? This ranking sorts giant sauropods by size and class within the Megakingdom, and Vividen explains the reasoning for each mass estimate. You may be surprised at the true winner in this contest of the largest sauropod dinosaurs.
How big were dinosaurs? Were they bigger than blue whales? The biggest dinosaur may have been Bruhathkayosaurus matleyi, a huge titanosaur from India, according to a new study by Gregory S. Paul and Asier Larramendi. The two paleontologists analyzed dinosaur size limits to find out the answer to the question: how big were dinosaurs? When it comes to the comparison of “Dinosaurs vs blue whale” and “Dinosaurs vs mammals,” it can go either way. Blue whales are often cited as the biggest animals ever, but with this recent discovery about giant sauropods like Bruhathkayosaurus and Amphicoelias (now Maraapunisaurus) that may not be true. Dinosaurs the size of a blue whale could be more common than previously thought, with multiple sauropod species weighing well over 100 tonnes.

Cope: The New KingVividen: Paleontology Evolved2023-09-02 | How big was T.rex? New data shows that the T.rex E.D. Cope, the "Copium rex," was the biggest theropod ever found, increasing theropod size limits to new heights. T.rex was a powerful predatory megatheropod. While Sue and Scotty are currently cited as the biggest T.rex specimens, new measurements of E.D. Cope, from the Black Hills Institute in South Dakota, form a challenge for the title of the megatheropod king. Measurements of this new T.rex femur indicate that Cope may be between 10.6 and 12.4 tonnes, making it the biggest theropod by up to 2 tonnes. T.rex size is a hot debate in paleontology, and Cope just turned it into a bonfire. Copium rex!

Perucetus colossusVividen: Paleontology Evolved2023-08-02 | Perucetus colossus is the new giant of paleontology. The enormous basilosaurid whale had some of the most dense bones of any mammal, and its close relation to the giant predator Basilosaurus allows for skeletal scaling. Perucetus weighed between 85 and 340 metric tonnes, making it potentially the largest animal known to science. Perucetus was not only the size of a blue whale, but it may have been even bigger than a blue whale. It may also have been carnivorous, which would make it the largest predator in Earth's history.

(The Saltiel Law Group)A Dinosaur The Size of a Blue Whale? Bruhathkayosaurus matleyiVividen: Paleontology Evolved2023-08-01 | How big were dinosaurs? Were they bigger than blue whales? The biggest dinosaur may have been Bruhathkayosaurus matleyi, a huge titanosaur from India, according to a new study by Gregory S. Paul and Asier Larramendi. The two paleontologists analyzed dinosaur size limits to find out the answer to the question: how big were dinosaurs? When it comes to the comparison of “Dinosaurs vs blue whale” and “Dinosaurs vs mammals,” it can go either way. Blue whales are often cited as the biggest animals ever, but with this recent discovery about giant sauropods like Bruhathkayosaurus and Amphicoelias (now Maraapunisaurus) that may not be true. Dinosaurs the size of a blue whale could be more common than previously thought, with multiple sauropod species weighing well over 100 tonnes. But was it really possible that there were dinosaurs the size of a blue whale? Find out here on The Vividen!

(The Saltiel Law Group)New Marine Superpredator! Analysis Of The Swiss Tyrant and Other Giant Predatory IchthyosaursVividen: Paleontology Evolved2023-07-30 | A new giant predatory ichthyosaur has been discovered! Paleontology presents us with the Swiss Tyrant, a giant sea monster that may be bigger than Livyatan and nearly as big as Otodus megalodon. This oceanic superpredator rivaled Livyatan and O. megalodon as one of the biggest underwater monsters in natural history. In this video we analyze the Swiss Tyrant Ichthyosaur in addition to other gigantic macropredatory sea monsters like Shonisaurus, Shastasaurus, Temnodontosaurus, Cymbospondylus, the Lilstock Monster, and the Aust Colossus. Ichthyosaurs were the largest marine reptiles known to science, with the largest (such as the Aust Colossus) surpassing even the biggest sauropods in size. Such record animals are rare in paleontology, making this discovery of the Swiss Tyrant ichthyosaur even more valuable. It would have been a terrifying raptorial predator ten times the size of an elephant. Was it bigger than Livyatan? Was it bigger than O. megalodon? What other marine superpredators were bigger than Livyatan or bigger than O. megalodon? Was the Aust Colossus really a mythical 100+ ton giant predator? Find out here in one of the most comprehensive video analyses of macropredatory ichthyosaurs to ever be published!

(The Saltiel Law Group)Was T.rex A Better Swimmer Than Spinosaurus?Vividen: Paleontology Evolved2023-05-13 | Spinosaurus and Tyrannosaurus are two of the most famous and culturally influential megatheropods, with a fanboy rivalry dating back to 2001. One was a huge water-based predator from North Africa that feasted on fish the size of cars, and the other was an even bigger North American tyrant that took on living tanks. Our understanding of both species has changed dramatically since they were discovered, but Spinosaurus in particular has been the subject of back-and-forth drama regarding its ecological role. Was it a bipedal monster that took on other theropods? Was it a knee-deep wader? Or was it an aquatic pursuit predator that used its powerful tail to dive under the surface and hunt prey in the water column? A new study indicates that, at least in this respect, Spinosaurus and Tyrannosaurus had something in common: the way that they used water to hunt.
The idea that Spinosaurus and Tyrannosaurus both hunted in water may be a strange one, but ecological modeling and morphology based on biophysics seems to indicate that it may have happened.

From movies to books to video games, theropods have left a cultural footprint unlike any other group of extinct vertebrates. And even these terrifying and majestic animals have an elite group within them: the megatheropods. If all theropods formed the ranks of a military, then these are the officers, the generals, the supreme commanders. There are a few definitions floating around the internet about what exactly a megatheropod is, so here’s a modified version of mine from 2017. A megatheropod is any theropod dinosaur that consistently attains an average adult mass of 5000 kilograms or higher. This definition is more exclusionary than my old video, and that’s because while researching this I put an emphasis on consistency and utilizing multiple mass estimates per species from different sources, which I’ve linked here.

Advanced Dinosaur Larynx DiscoveredVividen: Paleontology Evolved2023-02-16 | A specimen of Pinacosaurus has revolutionized the way paleontologists think about how dinosaurs sounded and communicated. 3-D laser scanning revealed a complex, advanced larynx inside of the ankylosaur's hyobranchial apparatus, revealing that they were likely able to produce birdlike sounds. Since ankylosaurs are so distantly related to birds, this may mean that other dinosaurs, like T.rex and Spinosaurus, were able to do the same. This study lends credence to the idea that some dinosaurs were able to develop biological culture, as complex communication strategies would make it easier for individuals to cooperate and develop mutually-beneficial intraspecific relationships.

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.

Giganotosaurus never lived in the same time or place as T.rex, but was depicted battling a T.rex in the prologue to Jurassic World: Dominion. The Giganotosaurus in the video was extremely large. Was that gigantic theropod realistically depicted? Morphology and anachronism aside, here we explore the potential of a Giganotosaurus actually growing to such a massive size. Based on genomic studies done by Romanov et al (2014), the domestic chicken is the closest living relative to nonavian dinosaurs. That makes it the best comparison for population dynamic studies. If we treat the Giganotosaurus population as having similar extremes as those of chickens, we arrive at an individual that weighed over ten metric tons.
