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.

    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...
