oi vile shrubo you dont have giant dinosaurs, a stegadon is probably the same size as a stegosaurus and a carnosaur is based on a very primitive reptile (postosucus, i think) probably pre- to early triassic. Terradons are based on a type of Pterosaur, some of which often had wingspans over 7 metres (20 feet)
so hah lizardmen dont hav giant dinosaurs!!
P.S: bet you didn't know but i have paleantologist to fall back on if a fail at being a scientist
