This is a drawing from Seba, 1734. The caiman depicted is what Schneider based his Caiman trigonatus on. Many authors now consider this drawing to represent what we now call Paleosuchus palpebrosus. This causes some possible nomenclatural problems. Certainly, the shape of the head, and the rows of scales bear a resemblence to palpebrosus. The large keels to the scale rows, though, is very much a trigonatus aspect. Of course, the picture is hardly realistic, but it does fuel a bit of discussion!
