Here's a good point my dad brought up today at the doctor's, that arose from a picture in a magazine. That picture featured Albertosaurus being attacked by Deinosuchus (the artist's name slips my mind but it is an excellent piece). And that's what brought about the good point, well two of 'em. See if you notice anything particular in the picture below.
Well, there's one thing. It's going for the face usually (or the leg). Whenever you watch nature documentaries, that's usually what you see. But most pieces have it going for the midsection or tail. Another point is: its an herbivore! Nile crocodiles today usually don't go after lions or hyenas, they generally attack zebras and wildebeest. But most paleoart pieces show it (Deinosuchus) attacking an albertosaur or a T. rex. I've seen some pieces showing it attacking Parasaurolophus, but that seems to be the only herbivore it attacks. What happened to the other creatures it lived with? What about Kritosaurus or a ceratopsian? Now, I'm not trying to being all high and mighty, standing on my soapbox and such, but it is an interesting observation.
