I don’t know the exact time for them, but I do know that a Giga will be held for exactly 10s and the time will go up from there because the smaller the dino, the more time in the trap.

Causally traps Giga dodo walks over

How long does this work on a brontosaurus

This could work on a giga except it only works for 10 seconds. But I'm trying to use this for an allosaurus

Does anyone know how long this keeps a Dino trapped and if it makes a difference if with larger and smaller dinos?
