Crassigyrinus - Scotland’s Prehistoric Killer Tadpole From Hell | Non-Dinosaurs EXPLAINED
Ғылым және технология
Among the coal swamps of Scotland once swam a giant killer tadpole beast with diminutive legs that pushed itself along with a huge paddle-like tail to engulf its prey with a gaping maw rimmed by many rows of teeth. This critter is the tadpole from hell, the Crassigyrinus!

@@theangrysuchomimus5163 yeah true, though the froglets do still increase in size depending on the species and their adult average size. Like man gray tree frog tadpoles if they have enough room, they get to the size of small fish, but they do shrink way down once they turn to their fully aquatic to semi transitional phase. And the largest of them when fully grown aren't too much bigger than the palm of your hand or the middle of your hand, and that's only the largest, which mostly are the females and few males get that size. They can be quite small as adults tho too. So yeah unless we find more fossils of this species and potentially find an adult specimen if they do go through metamorphosis.

Nah actually the frog form is super chill
It looks like a stem tetrapod evolving into something like a snake. The hind limbs could have been used in mating like the limbs of stem snakes and vestigial claws of some snake species today.
"Crassigyrinus could reach up to the length of 1.5-2 meters, or 4.9 to 6.5 feet", which would make it about as big as a Japanese Giant Salamander. Only even more funny looking (and with longer teeth)!
I prefer these early creatures. Discussing dinosaurs is like watching a finale without a story when you haven't learned about earlier forms.
The TRUE NOPE ROPE! Love these kinds of videos, thank you for making this.

One of my favorite prehistoric creatures!
The geology matches: The Atlas mountains in N.W. Africa, the northern tip of the Appalachians in "New England" U.S.A., and mountains in Scotland, were once part of a single mountain range ... on Pangea. One of my favorite weird facts.
This is one of my faves! Thanks for the cool vid

They found these in West Virginia USA, I live in Turtle Creek Pa in the Casselman formation Pennsylvanian age rock with mostly plants and some animals fossils can be found

Interesting video - thanks a lot!
Oh this Killer Tadpole is pretty badass and yes prays to the amazing models bu from Kuizm and animation from Cameron Also I wish y'all are having a great day.
My personal favorite tetrapod
OOOOOO giant tadpoles
Things look like Elden Ring shard bearers. Even a level 713 wizard king would shit his robe and some of the magic out of his body, permanently. Smeagol don’t even want that smoke.
This is really excellent work. Though taught geology in the UK, I don't recall anything about the Scottish Carboniferous, let alone killer tadpoles! (y) Also interested to see you found some info on spores and palynology. This is one area I've always wanted to know more about (Are there accessible keys to genera of spores and pollen on line?). I've searched for understandable quality uploads on palynology, but they all seem to be in languages I can't follow, and mostly only intended for fossil fuel industry worker trainees. There's a sizeable gap to fill with respect to microfossils in general...

@Snorbo geologically, yes. but there is an undeniable difference in ideology between Scotland and England, we want to move forward and they are determined to go back to the empire days. It won't be our problem soon, we won't have to just settle for whatever England wants, we'll be able to decide how our country is run instead of having successive conservative governments that we didn't vote for forced on us, and we will be free to decide on our EU membership status. I'm a Scot, not a Brit. The mindset is not the same.
