World's Biggest Underbite Came Before The Dinosaurs!
Ғылым және технология
The world’s oceans have changed dramatically over time. We live in a world in which the oceans are dominated by giant mammal and fish predators. Go back to the Mesozoic and its various families of reptiles. Go back to the Paleozoic, and you get gradational ecosystems of all types of weird animal groups calling the shots. From the Silurian to the Devonian periods, fish finally evolved jaws with teeth to crunch up the invertebrate animals around them, allowing them to take the top rungs of the ecological ladder. New remains of one of these fish have been found and show it to be unlike anything from its group every found. Let’s meet Alienacanthus.

Sea scorpions: "I am inedible." Dunkleosteus: "and I am Iron Fist."
It's interesting that elongated jaws keep independently evolving over and over again. They aren't practical enough to be the norm for aquatic predators, but they fill enough niche functions to be consistently viable.
Finally, the fullbeak fish
Shoutout to whoever named an animal "excalibosaurus", what a legend
I appreciate the extra effort taken to learn how to pronounce the Polish names! Maybe a tiny detail, but always a welcome surprise. :) Cheers!

I try my best 👌
The jaws of the Dunk look like literal bolt cutters..
I was lucky enough to find piece of Alienacanthus jaw in Ostrówka, Poland about two years ago during one of field courses. I'm so happy to see this new paper about this bizzare fish!
Imagine if jaws never evolved. Christmas dinner would be interesting as would getting a kiss from Grandma.
Amazing, Alienacanthus is very instresting, Placoderms seem to have followed an evolutionary pattern that seemed to make the organism much more capable when it comes to protection. Large, strong armour and sharp jaw structures. Those are just my personal thoughts and opinions.

Ive missed these ❤ my insomnia filler
Very interesting video! Great return!
I see I'm not the only one who has trouble correctly pronouncing 'Dunkleosteus'. The fact that I *know* I do it means I spot it immediately when others fall foul, lol

It's name after Dunkle, so, Dunkle-osteus
Another interesting character from the dunkolostius family and clade of the fossil record.
I wonder if having teeth in the lower jaw would allow the fish to get close enough to “stun” or hook its prey before getting into the jaws
The downward facing teeth and relati9ve robustness of the protruding jaw remind me of the arrangement of protosphyraena and aspidorhynchus, as well as a cretaceaus lizardfish whose name I forgot. Overall elongated lower jaws, though rarer for whatever reason(probably hydrodynamic) than elongated upper jaws in aquatic vertebrates, are far from being a very unusual adaptation, compared to say, eugeniodont dentition.
Dunks are my fav of all sea animals
Мне нравятся эти селёдки😎
🤪👍
