What's your stance on bringing back extinct species?

[Anomalocaris]

dissipation of waste heat is a phenomenon governed by physics, a large creature weighing at least several hundred pounds being able to dissipate the heat generated by producing fire able to melt Castlegate its gut without cooking the creatures organic components and turning it into carbon dioxide is the violation of physics

Why would the fire be in its gut? I think of it more like a controlled belch, with the methane not igniting until it exists the mouth. And it’s not out of the question for an animal’s skin to be heat-resistant enough to bear up to the residual heat from a flame moving away from it.

if the methane is expelled through its throat and ignited in its mouth the problem would be the same.    the inside of its mouth would be subjected to radiant heating from 3000 degree kelvin flame.
