- I’m very late in getting a post up about Miragaia, and there are several good posts out there already about this unexpected fossil and its unusual anatomy. So I’ll just say, “Lookit that long-necked critter!” and encourage interested readers to download the paper and check out the posts listed in the “Further Reading” list for analysis and commentary on this impressively cervical stegosaur.
