Researchers have been puzzled by evidences such as the Berezovka mammoth for years, but not all deductions are logical, as we see in this report:
In fact it is this incredible preservation which lies at the heart of today’s post. If you saw the 2004 film the Day After Tomorrow you might have heard that some mammoths have been found ‘flash frozen’ with preserved food still in their mouths.
This paper supports the idea that a sudden accident which plunged the mammoth into a crevace was responsible for its sudden demise and preservation. What does not support that idea is that the mammoth was suddenly frozen with tropical vegetation in its mouth, proving the weather just prior to the accident was warm and tropical.
