I think we’re all familiar with the work of one Dr. Mark P. Witton.
If you follow Mesozoic paleontology at all, you’ve probably read some of his papers (this one among many others) and you probably own his wonderful Pterosaurs book. Perhaps you even visited his inspiring 2010 pterosaur show in London. I have to imagine you read his excellent paleo-blog, too.
Heck, maybe you’ve met him at SVP, perhaps back in 2009, when mutual friend Julia Heathcote introduced you but you were too intimidated and tongue-tied to say anything intelligent. I can tell you, from that brief encounter, that Dr. Mark P. Witton is the only person I’ve ever known who can successfully pull of an ascot.

Sometimes you read a paper about a new fossil animal and just shake your head in disbelief. That was the posture I adopted back in 2014, when Atopodentatus unicus was unveiled to the world in the pages of Naturissenchaften. It’s a pretty good-sized marine reptile with a long tail and body, stout limbs, and a very small skull. From the neck down, this is a pretty nondescript critter that, according to its description, seems to have a close relationship with the Sauropterygia.

You may not remember, but I've briefly mentioned Saurosphargids before. In my hupehsuchian primer (that old chestnut), I tossed their name into the list of Triassic reptiles that were trying to make a name for themselves in a marine environment--perhaps to avoid becoming dinner for such the vicious rauisuchian pseudosuchians that were prowling the terrestrial environments. After doing some research, it turns out they are obscure to a fault--nobody's heard of them and there appear to be only four technical papers devoted to them. This should be an easy one, folks! Strap in and enjoy the ride. And stick around 'til the end for some fantastic art from Ethan freakin' Kocak of "The Black Mudpuppy" fame.

Another exciting entry in the "Primer" series (which started with hupehsuchians)! Again, we're tackling a Triassic oddity. There are lots to choose from. Indeed, I sense a theme!
The Late Triassic was an exciting time in the history of life on Earth. Ecosystems were finally in full recovery after the brutal Permio-Triassic Extinction in which life nearly died, and the ancestors of modern groups were becoming established—this is where you find the great-great granddaddies of birds, mammals, and crocodilians. However, even though the world’s food webs and the roles within it were similar to today, the actual composition of those roles was much different. Mother Nature was going through a period of divine inspiration: the predator guild was ruled by large, vicious (distant) relatives of crocodiles—Postosuchus, Carnufex, and Teratosaurus—preyed on their own herbivorous relatives, the armored aetosaurs. These critters looked like a cross between an armadillo and a crocodile, but grubbed around on the ground for plants. The other big role in the herbivore guild went to the dicynodonts, therapsid holdovers from the Permian with tusked, toothless, beaked jaws, some of which grew to be the size of cows.

|Yes, even these Ninja Turtles.|
What are turtles?
Everybody knows what turtles are. They're those reptiles that have enormous shells. Most turtles live in freshwater lakes and streams, but others are entirely terrestrial (tortoises) and a few are specialized for a marine life. The upper half of the shell is called the carapace and the "belly" shell is called the plastron. They lay a ton of eggs so that a few of the babies will survive to adulthood. Snapping turtles are really bad-ass and can bite your finger off.

Sorry I'm a bit late to this party. You've probably already read Darren Naish's and Jaime Headden's excellent takes on Yi qi, but I'm going to try something a little different. It's a FAQ. Let me know if you like this format or not for covering news.
So I heard there’s a new dinosaur in town!
That's no sauropodomorph...
Indeed there is! It’s a basal tetanurine from Chile named…Chilesaurus. It’s weird because it’s a theropod that has reverse-engineered some sauropodomorph and ornithischian features.
Wait, what? Did it have bat wings?
Oh, you’re talking about Yi qi, from China, also announced in two weeks ago.

How many modern marine reptiles can you name? I count two, broadly speaking: sea turtles and marine iguanas. Back in the Cretaceous, there were a few others. Many of the world’s oceans hosted the deadly mosasaurs, which were essentially marine-adapted monitor lizards. You also had the familiar but puzzling plesiosaurs; with their long necks, tiny heads, and wide rounded bodies, it’s still difficult to determine exactly how they made their living. Also still going strong were the ichthyosaurs—dolphin-shaped marine lizards with huge eyes and a taste for cephalopods. Marine iguanas weren’t a thing yet, but sea turtles were actually more diverse (and bigger) than they are today.
