Gigonotsaurus is a specsis of theropod dinosaur
When an anomaly opened up in an hanger at a fairground a girl investigated but she was killed by a Gigonotsaurus.When the A.R.C team arrive they sees the Gigonotsauurs attack and kill a young Argentinosaurus and they eat it.
Later when Emily Merchant realises that a young boy is heading straight for the Gigonotosaurus it nearly kills him but fails when Matt Anderson, Jenny Miller and Jack Maitland arrive and they stop it with their EMDs to keep it a bay. Later the Gigonotsaurus pair cause more chaos when they try to kill some more Argentinosaurus but are stopped by the team agine.
Later Darren Lake uses his EMD on the smaller Gigonotsaurus and it goes back through the anomaly. As the Argentinosaurus go back through the anomaly one lags behind and the bigger Argentinosaurus kills it and drags it back through the anomaly and it is joined by the other Gigonotsaurus and they eat it.
