Heres the catch, everywhere outside Antarctica giant creature remains etc, hide in plain sight as rocks/ mountains because they were covered in mud etc but in Antarctica there are some (enough to upend most peoples understanding of history) that are frozen solid in the ice and still bleed (blood falls) and are biological etc.

Literally what? Hiding in plain sight, covered in mud? How are you getting upvotes? Frozen animals still bleeding?

What do you think happens after an animal dies and is left for thousands of years?
