Hi Bodine! I’ve repaired similar paint scuffs on my own Triceratops using Folk Art brand metallic acrylic paints. I know they make a color (I believe it’s ‘champagne’ or something of the like) similar to the light beige/dark cream part of the dino. You’ll likely have to get a handful of colors that are close to those on your dino, then mix them to reach just the right shade. Windstone has used a brown-tinted clear glaze to get the antiqued effect, which you may be able to replicate by mixing just a little brown paint into some clear gloss glaze, or you may be able to find one already colored brown. They make transparent paints for use on glass that might be useful for this, but I’ve never tried using them for this purpose myself.
There are better quality brands of paint out there, but the Folk Art brand is sold at most craft stores, so it might be easier to get a hold of.
Good luck! I love Melody’s dinosaur sculpts, so it’s good to see one being given some TLC 🙂
