These Ancient Animals Scarier Than Dinosaurs

Are there many who know what was BEFORE the dinosaurs? What animals lived 100 million years before them? Or what fearsome beasts lived 50 million years after them?
We bet there are far fewer experts here.
But there must have been some creatures living on the planet at those times, right?
And some of those creatures were scarier than the dinosaurs. If not in size, then in appearance.
Today you're going to discover:
What ancient fish had a bite force twice stronger than a modern polar bear?
What ancient bird had a wingspan almost as large as an F16 fighter jet?
What monster had the body of a bull and the head of a boar?
And many more interesting things!
Ancient animals scarier than dinosaurs.

[@raminagrobis6112]

In addition to their pseudoteeth (a serrated lining of the mouth, not embryonically or histologically equivalent structures), the tiny beady eyes of Dunkleosteus spp. contribute in giving them a truly terrifying head. They are so disproportionately small they accentuate their alien physiognomy.

13:45 i think its a bottom dweller. The serated protrusion on its face and fins would be scraping up the sandy ocean floor to feed on other small fish and crustaceans. The protruding spikes on the back would be for protection from attack from above?

[@VitchAndVorty]

What if Dunkleosteus actually had fleshy lips? We tend to perceive fossils as face values. From the skeletons alone, Hippos are so goddamn scary. Beefy looking build, terrifying teeth... It'd be interesting if the giant terrifying fish actually had lips... Imagine the horror.

[@user-sk8ts3cj7f]

The serrations on the small doriospus were possibly a defense mechanism in the event a larger predator tried to swallow it. It also could have been poisonous.

These creatures resemble animals around right now because there are forms that are manifesting on Earth in the form of these species. E.g. the vulture form, elephant form, shark form, etc.

At around 16:40 it says the Mosasauru's main pray was sea turtles, but how do we know this? The shells of the sea turtles would be more evident than the soft bodies of octopuses and other cephalopods. And the beaks of a cephalopods would probably pass through the animal more easily than the shells of a tortus. I also now wonder what cephalopods might have existed back then, it would be very difficult to find evidence of cephalopods or jellys (or similar) from that time period.

[@user-sk8ts3cj7f]

Another possible evolutionary example of the large flightless birds could also be the roadrunners of the American Southwest. I believe they hunt lizards and small snakes, meat sources for their food. Sound familiar? Just a thought.

[@schisophrenic]

Doriospus, the snout resembles a sword fish, it might be used for defence from prediters and maybe even to cut down plant life in the seas, the protrusions on the fins may have been used in the same manner, from the small size of this creature it may have had a diet of plankton and maybe even shellfish, which could also be the reason for its protrusions, for example ammonites shells were tough and barnacles stick to things, meaning that it may have needed to break into the shells to get to its food

[@thearishok2802]

[@LtJackboot]

12:53 I surmise that the body protrusions and especially the serrations thereon may have been a defense mechanism to prevent larger predators from swallowing doryaspis.

[@FatGamerDad]

I'd say anything during the era when there were giant insects running around are more terrifying than the dinosaurs

[@jacob6885]

In aircraft, forward swept wings create an "unstable" aerodynamic situation. Which makes controlled stable movement more difficult and less energy efficient, but also makes the vehicle more agile and responsive. Hydro and aero dynamics share many principles. If the same applies so water, then perhaps this fish evolved forward swept fins to better evade predators or better bring its "spear" to bear. The energy cost of less efficient hydrodynamics also implies a food rich environment. (Given that efficiency is a major component in most creatures.)

do you think the earth is flat

[@nrodas255]

😂 No. I know it's not flat. I was in the military. We had to look through very powerful scopes to see out up to 20 kilometer distances. Even on a what appears to be a flat stretch of land, you cannot see entire structures that were out past 10km. You could only see the tops of the structures or the heads of people that I knew were there, such as other teammates when we did split team operations. i.e.) because of the gentle curvature out at these close distances, only a percentage of the objects were visible instead of the entire person or structure as would be expected on a flat earth.

Dorispres. Lived life like a stingray or flathead. It wasn't pelagic due to shape and aerodynamics. The wings were used to help anker it to reefs and the sea bottom, hence why it also had ridges on the wings to give more traction, the nose is very similar to saw sharks and such, witch are usually marine animals that hunt from the bottom upwards. Where as stingrays hunt from on top of the prey so they just need surface area for broader chances of engulfing the prey....Just an assumption from someone who knows nothing about the creature.

Fororakos did not replace dinosaurs, they are dinosaurs. Small theropods such as raptors survived a mass extinction event 65 million years ago. And they are the ancestors of birds. Moreover, they already had feathers. So immediately after the extinction, the world was flooded with many feathered therapods, which became the arboreal birds of prey. On most continents, they were later replaced by large predatory mammals and only those birds that were able to occupy the air survived. But in isolated South America they survived and continued to evolve. So Fororakos is the same dinosaur that ran across these same lands 100 million before. He just got bigger and replaced his teeth with a sharp beak.
