Or You may use bryce for this. From top view in render option, select altitude mask and You'll have a height_map. For textures one (don't touch camera) but deselect altitude mask and You'll get the skin_map. Both of them save as bmp.
Next open wed, chose open file (bmp) and open your height map. Nest open skin and attach the skin map. That's all

To create dinosaur stuff...
It's many options. F.e.
define hungry, skill1;

function go_eat
{
function to find and go to some herbs, with trigger.
like if(event_type == event_trigger) && (you == herbs)
{
animate_eating();
my.hungy += 10 * time_step;
}
}

function dinosaur
{
my.hungry = 100;
while(1)
{
my.hungry -= 0.1 * time_step;
if(my.hungry <= 50){go_eat();}
wait(1);
}
}

wtf?

Dinosaurs?
