The popularity of dinosaurs - for better, for worse

This article is being cross-posted at the website of the London-based 2016 Popularizing Palaeontology workshop as part of a series of blog posts focusing on the discussions and themes of that event. Over the course of this two day workshop curators, artists, historians and palaeontologists presented talks and led round-table discussions about the history and current state of palaeontological outreach. I presented a talk at this workshop - entitled 'The importance and impact of palaeoart in [...]

nationalgeographic.com Over eight decades ago, while pondering the heavily-armored dinosaur Scolosaurus, the eccentric paleontologist Franz Nopcsa proposed what is probably one of the oddest ideas in the annals of paleobiological speculation. Scolosaurus was a low-slung quadruped that shuffled around what were then thought to be parched sand dunes. Even though its close ankylosaurian relatives had

Last week we took a look at some new art of animals from the Wealden Supergroup, the intensively studied, historically important Lower Cretaceous rocks of Southern Britain. We all know the Wealden for celebrity dinosaurs like Iguanodon and Baryonyx, but there's a heap of other interesting animals in there which get relatively little publicity. It's mostly these we're focusing on here, in the second (and final) part of these 'picture of the day'-style posts. As before, if you like anything [...]

Two Therizinosaurus cheliformis hanging out in Late Cretaceous Mongolia. The guy on the left thinks he's all that: she doesn't. Prints are available from my online store. Time for more new takes on old pictures. First up, above, is a reworking of my 2013 image of two Therizinosaurus cheloniformis, giant therizinosaurids from Maastrichtian deposits of Mongolia. Before we knew just how bizarre Deinocheirus was, these pot-bellied, small-headed and scythe-clawed animals held the title of least [...]

The authors provide what I believe is the first phylogenetic definition of the Polacanthinae (clade containing Polacanthus but not Ankylosaurus or Panoplosaurus) and their phylogenetic analysis places Taohelong as the sister to Polacanthus. Unfortunately, the article is in Chinese, so other details [...]

Vintage Dinosaur Art: Archosauria - Part 3

We've established by now that John McLoughlin's Archosauria was a beautifully bold, often highly prescient book, dedicated to overturning notions of dinosaurs as 'great fossil lizards' that were nature's way of killing time before those 'superior' mammals took over the place. McLoughlin illustrated feathered theropods and supercharged sauropods at a time when the number of people doing so could be counted on one hand. Given its boldness, it's surprising that Archosauria so infrequently [...]

For the first time since it was revived back in 2005, Doctor Who featured some tasty nonavian dinosaur action last night. Not only that, but they were dinosaurs in space (one has the distinct feeling that the title of Dinosaurs on a Spaceship came before the script). It was an absolutely brilliant episode that moved at a scorching pace, bringing together not only the Ponds but also Rory's dad alongside Queen Nefertiti and an Edwardian big game hunter. Of course.Now, don't get me wrong; while I [...]

As some readers may already be aware, I am known to draw dinosaurs occasionally. I'm certainly no artist - it's just something I do for a bit of therapeutic fun in my spare time. I've never considered my doodlings to be worthy of being presented to the world on LITC, but I have put them on Facebook for friends to see. After I posted a Giganotosaurus portrait recently some people - mostly named David and Niroot, not to mention Sharon - said that I should put it up here. So, slightly embarassed [...]

An armored dinosaur gets a second opinion—and the crazy-straw nasal passage survives!

In 2008, Ryan Ridgely and I published an article on dinosaur sinuses and nasal cavities in the Anatomical Record. One of our findings was unexpected to the point of seeming almost dubious. We found that, despite what had been stated in the literature, including my own published statements, armored dinosaurs (the plant-eating, tank-like ankylosaurs) didn’t

My brief forays into ornithischians is usually relegated to those heterodont taxa that are basal ornithopods and their ancestors (but not descendant thyreophorans, ceratopsians or pachycephalosaurs) because of the wonderful arrangement and oddity of their teeth. Once you get past them and into ankylosaurs, stegosaurs, ceratopsids, and iguanodontoids, things get a little more boring when

But they can still fly! Quite a view! See the entire set from the move on Flickr. If you’ve never seen a dinosaur fly, then you weren’t in the vicinity of the museum around 11 am last Friday – at which time it was almost impossible to miss our airborne ankylosaur. Pretty cool! The ankylosaur

A Closer Look at Ankylosaur Armor

Many dinosaurs were adorned with spikes, horns and plates, but it was the ankylosaurs that took armor to the extreme. These dinosaurs were covered in bony armor from snout to tail-tip, yet, as a new study suggests, there may have been more to some of these structures than just attack and defense. As reviewed by paleontologists

Sauropelta Solved!

A nagging problem in our dataset has been the issue of the Sauropelta edwardsi specimen AMNH 3032. Its tibia seems way, way too short (even for ankylosaurs), and it’s thus a bizarro outlier. So, I finally got my behind into gear to check out the problem. Was the measurement a typo? Was the tibia incompletely preserved?

Doing the Hadrosaur Hop 

Dinosaur Tracking [2009-12-15 16:51:12]  recommend  recommend this post  (46 visits) info
I always feel a bit sorry for hadrosaurs. They are sometimes referred to as the “cows of the Cretaceous,” herbivorous dinosaurs that lacked the impressive armor, spikes, and horns of their relatives the ankylosaurs and ceratopsians. This does not mean that hadrosaurs were entirely defenseless against the tyrannosaurs that so often preyed upon them, though.
