After they become trapped in the Cretaceous Desert, Abby and Connor briefly see a flock of pterosaurs flying over the sand dunes in the distance. Like the pterosaurs from episode 1.3 and 4.1 of the original Primeval show, these pterosaurs use the same CGI model used for the Pteranodons. Another, identical flock of unidentified pterosaurs are briefly seen flying over the Cretaceous Rainforest in episode 2.4, it is unknown whether or not these were the same species.
