Here is a shortlist of some of my favourite dinosaurs in my collection. They're roughly 1:1 scale at 75dpi, scanned at night on a flatbed scanner. The dust gives it a good texture.
I prefer dinosaurs which can fit in the palm, are roughly painted, mass produced, and cheaply cast. I collect dinosaurs that repeat moulds which depict the decay of the sculpt over time. Try to keep an eye out for repetitions, that's the fun.
Also some aren't dinosaurs, but they get a rule of cool pass.
That's it for the scans, but by no means all of the dinosaurs I have.
