An old bull Apatosaurus ajax, still trucking alone despite the fact that he's been practically crippled by the loss of most of his tail (and some issues with nutrition and arthritis, from the looks of it. :( ). He's found a good watering hole, though. Green stuff be near!
Cameo by an Ornitholestes--who seems to be going "Daaaaaaamn..!"
Try at some digital dinosaur stuffs. :D
