Europe's Shield: The most complete European ankylosaur

Europe's Shield: The most complete European ankylosaur

Late last year Europe got a brand-spankin' new ankylosaur, Europelta carbonensis. It's the most complete ankylosaur yet known from Europe (unless you consider Scelidosaurus to be a basal ankylosaur rather than a basal armored dinosaur). Let's take a look at the anatomy of Europelta, with an emphasis on what we know (and aren't so sure of) when it comes to reconstructing its armor.

Sauropod Gallery Overhauled!

Sauropod Gallery Overhauled!

Let's start out 2014 right, with a bunch of new and overhauled sauropod skeletal reconstructions. All of the reconstructions of your favorite four-legged dinosaur behemoths (and some of their smallish ancestors) have been brought up to date. For more on this and a look at some of the anatomical changes that have been incorporated into this overhaul click beyond the fold to check it out.

New and improved galleries!

New and improved galleries!

For those of you wondering why the pace of content has slowed down, it's because I entered a PhD program in paleontology at the University of Wisconsin-Madison this fall, and I lost what was left of my free time. But that's not to say that there hasn't been substantial work going on behind the scenes of SkeletalDrawing.com!

First and foremost, there is a new skeletal gallery featuring some of my non-dinosaur reconstructions.  "Non-dinosaurs" is admittedly a pretty broad category, and indeed it features everything from the proto-dinosaur Silesaurus to crocodylomorphsturtlesmammals, and even the basal tetrapod Ichthyostega.

Mass estimates: North vs South redux

Mass estimates: North vs South redux

I have good news and bad news - the bad news is today is not the day you get a general estimate of the mass of Spinosaurus. I know, I know, and I'm sorry. Here's the good news - in preparation for a deeper look at the challenges of estimating the mass of Spinosaurus, I've produced far more rigorous mass estimates of Tyrannosaurus and Giganotosaurus from GDI, and I got some surprising results.  Jump below the fold to see who is bigger (and why I think this is so).

Scaling issues - a minor irritation?

Scaling issues - a minor irritation?

The Super Spinosaurus? post produced some interesting conversation; in particular Marco asked a good question about whether using the skull of the South American spinosaurid Irritator would have a material impact on the size of the animal. Let's take a quick look at Irritator's skull, and then a broader look at how these sorts of questions do (or don't) impact mass estimates.
