When this Anomaly opened, it was located twenty to thirty feet in the air above the ground (on the present side at least). Through it, came a Pteranodon and a swarm of Anurognathus into the skies above the Forest Heights Country Club golf course. The Anurognathus were later killed by a gas explosion, and the Pteranodon was sent back through the Anomaly, seconds before it closed.
- This was the first aerial Anomaly seen in Primeval.
- It is unclear whether this Anomaly led to the Jurassic or the Cretaceous, as Pteranodon lived during the Cretaceous, while Anurognathus was from the Jurassic.
