The Underwater cave Anomaly is a Anomaly that links a Underwater cave in the present to a unknown location in an unknown time period (Most likely Jurassic or Cretaceous).
An Anomaly opens up and a Dakosaurus comes through and heads straight for a submarine in which members of the A.R.C team are in.
Later with the Sub stuck the Dakosaurus tries to go back through the Anomaly but it closes before it can go back through the Creature dies not long after.
