Is this slop or just sloppy? What's with the little green arm behind the lightning and the weird meaty stego neck?

This is why stegosaurus should have waited for backup from the council before trying to arrest T. Rex.

Uhh, about 83 million years separated these two species.

" Extraordinary claims need extraordinary evidence"

But honestly, I think this is intuitive and reasonable so I accept it as factual.

There is overwhelming evidence that this didn't happen in the Jurassic era: Stegosaurs had been extinct for tens of millions of years at that point.

The theropods ("possibly") electrocuted contemporary dinosaurs, not dinosaurs that had gone extinct 100 million years earlier.

Is there actually any biologic mechanism to generat and conduct electricity at a high enough voltage and current that it can ionize air over a distance as large as that (looks like at least 1/2m) without damaging the actual animal doing it?

Looking around, electric eels can do 860V, which is well short from the 15kV needed to gap 0.5m of air at sea level, plus that animal's skin would need to be crazy insulating for all that power to not just go down the most highly conductive way possible (all the nice conductive water all the way down to the ground contained in the animal itself) instead of having to ionize 0.5m or air.

I mean, we can always claim it was possible but lost, but then again we can also claim that for magic or animal teleportation.

Technically incorrect. There are no feathers.

Karl Popper's falsifiability says we only need to prove this didn't happen once.

Your move, denialists.

Sorry we all know the thunder lizard is brontosaurus, and thunder comes from lighting that's just good science

But we aren't completely sure

We don’t know that they developed space travel and left Earth either.

Creationism be like:
