Yes, I think it strange. No, I do not think partial mummification (her body was partially mummified) would account for it. Yes, the extremities and skin were mummified, but the organs in the thorax and abdomen were not mummified (and it would be stranger still if they were!) Most of the liquids which would drain out of body come from the abodmen and thorax. So, why no drainage of the fluids, none at all?
