Nicely done
It is interesting when people submit flashes that are simply what life used to be. I think this is a pretty realistic interpretation of the cretaceous period. Of course, it's been forever since I read about that stuff so I do not know if this is accurate. What is cool is that you manage to put such good designs on the creatures. As for the subtext, maybe it was something about Isreali-Palestinian relationships? That's been going on for so long it could be applied to really anything, you know.
The animation was fairly good, but it does seem a bit old by modern standards. The best part was how you tried to get rid of any bullcrap and just went for the nitty-gritty dinosaur story. No talking dinosaurs, no crazy effects, just authentic stuff. I was disappointed it did not go on longer. When I was a kid, I was just the biggest fan of dinosaurs there ever was.
