So we got these on Saturday from Petco. They're going to be cohabed until this evening as we get the other tank set up. I saw a post on tumblr about the differences between inland and rankins/lawson dragons, and they seem like both? We were prepared to return them, but when we went to a different pet store to check out other beardies, the hatchlings looked much like ours with the less prominent spikes, beards, head shapes, and most importantly you can't tell the size differences and Petco was unable to tell us how old they are. No matter what they are, they're very small due to their age. I only see "beard action" from presumably our male, and it never turns black, but rankins/lawsons do the same thing from what I understand, so that's not the best indicator. Here are my best pictures:
