Remember my post from last year about azendohsaurs and trilophosaurs? Well just the other day, paleoartist extraordinaire Gabriel Ugueto posted a sketch of something called Teraterpeton. I had no idea what this zany-looking reptile was, so I looked it up and was flabbergasted to find that it's a trilophosaur that is quite unlike Trilophosaurus. You'll notice that I did mention Teraterpeton in passing in that post, which must mean I didn't think it was a trilophosaur or at least was not unambiguously a trilophosaur. Turns out I'm incorrect--Teraterpeton is a perfectly good trilophosaur, and therefore an allokotosaur!

This is a small group—only three (but possibly four or five) genera have been named. They are atypical dromaeosaurs for a number of reasons, foremost among them the elongate, narrow snout packed with minute teeth which lack serrations. While most appear to have been small, one of them was one of the largest dromaeosaurs, approaching Achillobater and Utahraptor in terms of overall size.

All this has happened in the last twenty years. Heck, nobody knew about Halszkaraptor until a few weeks ago.

|Chilesaurus diegosuarezi by the impeccable Jaime Headden|
Ever since the publication of supreme oddball Chilesaurus (eat your heart out, Halszkaraptor), I’ve been dying for somebody out there to do a full description of the critter’s unusual skeleton. As Chilesaurus may hold the key to our understanding of early ornithischians (or not), this is an animal in dire need of detailed study. This past Sunday, a paper was published in a journal that I can’t pronounce—Ameghiniana—and it is not that description. However, it is very interesting, and since I imagine many of you don’t have access to, uh, Ameg-HEE-ana (?), I thought I might summarize the juicy parts here.

|Aelurodon ferox chasing Neohipparion, by Mauricio Anton|
You know, I never blogged about my SVP 2017 experience, more out of sloth than anything else. I can wrap up my thoughts with this sentence: it was fun but very lonely. For me, perhaps the most enjoyable part of the conference was the silent auction. I should have stayed for the following “real” auction because photos posted to social media afterward made it look insane, but I had a bunch of meds to do and an early start the next morning. I bid on several items in the silent auction, most of them 3D prints of interesting fossils, but I was quickly outbid past my own point of comfort for most of them. However, I was able to secure this nifty specimen:

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.
