Plateosaurus engelhardti being chased by predators.
The big dinosaurian predator/prey relationships of the late Triassic are still not fully understood. We know of big dinosaurian predators from the late Triassic with twenty foot long Gojirasaurus and seventeen foot long Liliensternus from the southwestern United States and Germany respectively, yet we don't know how common they were in the big predator guilds of the time, or how widespread such large (by today's standards) predators were in their world. Only time, and more discoveries, will tell.
Also, as a ranting aside to paleoart purveyors, I have to say that I am sick to death of the trend among paleoartists painting animals and then putting them in real-life photographic images; I find it a crass method at putting some sort of reality into the image when in the end it doesn't look anymore real than if you'd painted the entire image from scratch; it just shows you exactly what it is: a real life image with a synthetic dinosaur plopped in--bad taste and form in my opinion. I haven't seen one image done in that fashion that I thought was genuinely worth while and I will never create a piece in such a way no matter how strapped for time I am.
Oh, by the way, those out of focus things in the background are early pterosaurs--thought you should know...
