The roll of Gracilisuchus starts in issue two of the Jurassic Park: Redemption series. All that is seen of them in issue two is their claws as they are released from their cage by Lewis Dodgson, upon orders by the shady investor. While Dr. Backer took a group out to search for the loose Carnotaurus, Wu stayed back and was killed by the Gracilisuchus that Dodgson released.
Later on in the series Dr. Backer released them from their cage, allowing them to attack and subsequently kill Peter Ludlow (the shady investor.)
