"Promised Land" by Steven Utley

Set in the prehistoric past, this is a straight-forward tale about a dying paleontologist who curses the discovery of time-trave; it invalidates his work, since people can just travel to the past instead of mucking around with fossils, and he can't use it as he is dying. But some people who care for him are willing to do some subterfuge to fufill some of his wishes.
