Just to be clear here... I'm talking about the sky 100 million years ago (as
given in your subject header) and not about 104,000 years ago (as given in your
message).

104,000 years is certainly enough to distort many of the constellations, but not
always beyond recognition- the sky would be odd, but not totally unfamiliar. 100
million years would produce a totally alien sky.
