It's been a while since we covered any of these nifty little premiums from Post Cereals, mostly because I thought I had them all - silly me! We last visited these little guys in March of 2013 but apparently there's still a couple out there I missed. Although not necessarily Flintstones tie-ins, their fun, cartoony appearance is a definite natural for pairing with Flintstones figures. Although Post offered other dino's, the ones issued in 1990, '91, and '92 were the most fanciful and colorful. They were all made of a hard PVC plastic in a wide variety of colors by H-B Productions for Post Fruity Pebbles or Cocoa Pebbles cereals. Our latest visitor is a bright yellow Stegosaurus and measures about 3" (7.6cm) long. Enjoy!
