The museum I work for used to sell the hatching Protoceratops and Maiasaura years before I came on board. I wish they were still in production, they were apparently hot items in the gift shop!
The Protoceratops and Maiasaur are on ebay really frequently, if you don’t have those. 🙂 They are the easier dinos to find too, so you won’t have to shell out a pretty penny. I am working on the dinos for my sister, and I was able to get a Pro and a Mai on ebay for a reasonable price.
