You certainly are the skeptic. Even to the name calling
Your theory does not hold water and seems composed mostly of hot air. You figure it out.
What theory of mine?? How so??
Where aside from questioning the description did I propose an alternate theory?
My comments were directed at the description.
If based on the description it seems perfectly reasonable to you that over time, these creatures were one-by-one carried, pushed, pulled and dragged upwards of 250 meters through 6-7 inch passages to their final resting place, fine but I remain skeptical.
