Mega Miniatures will soon be releasing three new animals to join your 25/28mm prehistoric models. Miniature painter Roger O'Dell paints Mega Miniature's new releases for their catalog. Once they have the photos he sells them, which is how I saw these three pics. It will probably be a month or two before they are available for purchase—I can't wait! The saber tooth cat looks great. I quite like its gaping mouth / swiping-paw pose. I'm wondering how it will compare to the saber tooth cats sold by Pulp Figures.
Next up is a giant ground sloth. I'm wondering just how giant this sloth model will be. The image file name was labeled as megalonychidae, so that should mean this sloth will be a bit smaller than my painted Marx megatherium. Check out the Wikipedia article about prehistoric ground sloths.
Lastly, we have an Andrewsarchus. These snarling beasts pre-dated man by millions of years, but that shouldn't stop anyone from using this model in a lost lands pulp scenario.
