@maniaUFO All dinosaurs, including aquatic ones like the Pliseosaur and the icthyosaur, were Air Breathing. So you would see any such Lake Monster surfacing regularly and could easily film it. So Lake monsters are made very differently to dinosaurs.
@BrianRoemmele No...The transporter works like this: It scans the body, turns each atom back to its pure energy form, transmits that energy wirelessly (like radio waves , then turns the energy back into the Original atoms. Much more complex than you made it sound.
