"Prorichthofenia": brachiopod horn corals

April Fools' Day not only falls on a weekend this year, but Easter, so I wouldn't be surprised if the typical crop of spoof news articles and blog entries is thinner due to other time commitments. Not that I mind too much; the whole thing gets old, year after year. Still, with April 1 in mind, here are some fossils that aren't what they seem: brachiopods from the Permian of Texas that put a lot of effort into being horn corals.

Three weeks of ankylosaurs and pterosaurs

March has been busy over at The Compact Thescelosaurus, with ten new entries adding three ankylosaurs, four pterosaurs, and three theropods. There's still a week to go, too. Sometimes people talk about following taxonomy as another kind of stamp collecting. I have a more artistic point of view, with each specimen as more along the lines of tiles in an incomplete mosaic or notes in an unfinished song, each contributing to a greater whole. It just so happens that the currency of the realm is in species and genera. (I also keep track because you can't tell the players without a program!) As usual, I'll leave the theropods to others, except to say that it's nice to see Arkansaurus finally graduate from informal name to the big leagues, thanks to Hunt and Quinn (2018) (the name has figured in print since 1983, after all). A few comments on the ankylosaurs and pterosaurs:

Marshalls Creek Mastodon

This is something of an apology. I gave a paleontological presentation for the folks at Delaware Water Gap National Recreation Area last September, and after I finished someone brought up the Marshalls Creek Mastodon. I'd been focusing on other topics, so the mastodon hadn't made the cut (for shame on my account!). I am now remedying that omission. For the rest of you who haven't been introduced to the fossil in question, you can also find accounts in Hoff (1969, 2001), which are my primary sources. The Monroe County Historical Association also has a brief online account.

Ankylosaurs have had a good few weeks, publicity-wise. First we get some actual science done on the long-held belief that they were prone to "bloat and float" (if you don't like to contemplate recently deceased animals, I will simply say yes, it looks pretty good; if you'd like a less-technical summary, go here). We've also now got the oldest record of a true tail club, wielded by the newly minted Jinyunpelta sinensis.
