Biosyn is a fictional genetics company from the novels Jurassic Park and its sequel The Lost World.



Biosyn was one of the competitors of InGen, the genetics company of John Hammond and the engineers behind Jurassic Park, and focused on many similar projects. In the first book, the company was engineering a new pale trout with the Department of Fish and Game of Idaho. Biosyn was working on ways for the trout to be easier to spot in streams, not die of sunburn, and to change its soggy and tasteless flesh.

Due to setbacks and the competition with InGen, Lewis Dodgson calls an urgent meeting to discuss with the Biosyn Board of Directors InGen and their genetic engineering of dinosaurs. According to Dodgson, there will be nothing illegal about obtaining the DNA; however, Dodgson pays Dennis Nedry $1.5 million to steal the embryos of 15 species from Isla Nublar. Nedry gets eaten by a dinosaur while the stolen embryos are lost forever.

In the novel The Lost World, Dodgson arrives on the island of Isla Sorna or "Site B". This time he comes to steal dinosaur eggs, along with two cohorts, Howard King and George Baselton. The plan fails, and Dodgson and his team are killed.

In the movie version of Jurassic Park, Dodgson is seen giving Nedry the means to steal the embryos, but Biosyn is not mentioned. Neither Biosyn nor Lewis Dodgson are seen or mentioned in The Lost World film; they are replaced by InGen.

Biosyn is the chief human villain in the Jurassic Park video games.
