Fosilized Mummy

I remember seeing an ancient Egyptian mummy, wrapped and preserved.  A woman, about 1.5 - 2 times larger than a normal person.  The specimen was very old, so much so that parts had turned to stone - the head and ribs mainly.  The interior was hollow - you could see right through the top of the chest down to the base of the feet.  Inside looked like a tomb and it was large enough for me to crawl inside and get a good look around.  I distinctly remember seeing an embalming pot with a liquid inside - the dead woman's urine.  I thought that this could be used for DNA testing.
