Context:

Michael Crichton's book (implied to be Jurassic Park, though not explicitly titled) is referenced in the context of ancient DNA and amber preservation. Beth Shapiro mentions that 'Michael Crichton, when he wrote his book actually wrote in the acknowledgments that he was grateful to the Extinct Species Working Group at UC Berkeley' and that discussions about ancient DNA inspired him. The conversation then discusses how the book/movie inspired scientists to try recovering DNA from insects in amber.
