I’m in the midst of drafting (for the third time) an upcoming post about Drepanosaurus and Avicranium but I doubt they’ll be done by the end of the month. However, I wanted to get something up on this darn blog because I'd like to maintain the illusion of being loyal to my seven or eight readers. So I’m going to briefly discuss something strange about ceratopsians that nobody ever seems to comment on: the weird peg teeth of basal neoceratopsians.

|Azendohsaurus madagaskarensis by Matt Celeskey.|
The term "strange reptiles" could apply to just about every animal I've ever written about on this blog, so you'll forgive me for not loving the name Allokotosauria, an up-and-coming group that was formalized in 2015. The name really says nothing about its members, the similarly newly-minted Azendohsauridae and the longstanding Trilophosauridae. These are archosauromorphs that sit well outside of the Ornithodira-Crurotarsi divide, and are instead related to such eclectic animals as rhynchosaurs and protorosaurs. As I suspect my readers have at least heard of Trilophosaurus, I'll start this essay by discussing Azendohsaurus.

Hopeful Dinosaurs. In that essay, I introduced you all to a group of near-dinosaur dinosauriforms called silesaurids. These small, quadrupedal, herbivorous critters all hail from the Late Triassic, but were impressively cosmopolitan, being found in the United States, South America, Africa, and Poland.

|The holotype of Thalattosaurus|
Thursday, March 30, 2017
Last week, the world was stunned by a new paper by Baron, Norman & Barrett (2017) that challenged Seeley's 130-year-old dichotomy of the Dinosauria. No longer were Saurischia and Ornithischia neatly separated. Instead, ornithischians were the sister group of theropods in a united Ornithoscelida, and sauropodomorpha (which now included Herrerasauridae as its most basal member) were spun off on their own in a weirdly lonesome Saurischia.
I spent several days writing a very lengthy post about this subject, as I considered it interesting and important. I also haven't really found the thesis statement for my WIP article on thalattosaurs.
