Despite still being a member of the cast (and also being prominently featured in this episode), Sherry Stringfield is not in the opening credits. The sequence used is the one intended for later in the season, after "Union Station," the episode in which Stringfield leaves the series.
"Coming back in the future like the dinosaurs in that movie" is a reference to Steven Spielberg's 1993 blockbuster adaptation of Michael Crichton's book Jurassic Park. Spielberg and Crichton had been working together on Crichton's script for an ER movie, but got a bit sidetracked and ended up making Jurassic Park instead. They would later renew their ER collaboration; Spielberg served as an uncredited executive producer during Season 1.
