Edmontonia rugosidens’s most distinguishing characteristic may be its back, which served as armor for the dinosaur. Bony plates called osteoderms covered this animal from the Late Cretaceous (about 100 to 66 million years ago). The osteoderms weren’t bound together, which allowed a certain flexibility and helped prevent puncture wounds from predators. Spikes along the dinosaurs’ sides added protection. Edmontonia is classified as a nodosaurid ankylosaur, and lacks the weapon-like club tail that relatives such as Ankylosaurus had. Instead, Edmontonia’s tails featured a row of triangular spikes that were perhaps used to slash aggressors. A keen sense of smell also aided these herbivores, helping them both avoid predators and find food. Edmontonia roamed Canada as well as other parts of North America and is in fact named for Edmonton, the capital of Alberta, where it was first discovered.

anonymous asked:

I can't stop giving my quadraped dinosaurs the 'elephant foot/leg' sundrome. Do you have any good references on how quadraped dinosaur foot/legs actually look?

Well, that depends on what kind of dinosaur! Sauropod hands looked like this:

While their feet looked like this:

(it’s not missing a head, that’s the angle)

Ceratopsian hands and feet can be seen very well in Saurian’s model:

While their Ankylosaur shows its hands and feet:

Stegosaurs’ were more like sauropods’.

And styracosternans’ hands were like mittens, while their feet were like chunky theropod feet.

Did Plant-Eating Dinosaurs Really Only Eat Plants?
An ankylosaur fossil with fish in its belly provides ancient evidence that herbivore diets are more flexible than they’re assumed to be.
By Asher Elbein

Ask a non-biologist about the differences between an herbivore and a carnivore, and they’ll tell you that it’s written like destiny in an animal’s bones. Carnivores have sharp fangs and claws; herbivores blunt teeth and hooves or pads. There are some animals that dabble on both sides of the line, of course, but the categories of “predator” and “prey” are usually seen as inviolate.

But according to an August announcement by the paleontologist Ji Qiang and his colleagues, at least one species of Chinese ankylosaur, Liaoningosaurus, might have bucked the trend. Discovered in 2001, Liaoningosaurus is already odd as far as ankylosaurs go. The largest known specimens are about a foot long, far smaller than the species’ more famous club-and-spike-tailed kin. The first Liaoningosaurus fossil found preserved a swatch of petrified tissue that Ji claims represents a plastron, a bony structure on the stomach common in aquatic reptiles like turtles.

The new specimen described has no plastron. Instead, it has a belly full of fish fossils, in addition to what appears to be the tail of some unfortunate reptile. Ji’s team also noted other odd anatomical markers: a loosely fused pelvis, relatively sharp claws, odd teeth, and a head similar to that of a turtle…

The excellently-named Animantarx – meaning “living fortress” – a nodosaurid ankylosaur from the mid-Cretaceous of Utah, about 100 million years ago. It was fairly small compared to other ankylosaurs, estimated to have been about 3m long (~10ft).

Fossils in the area are naturally slightly radioactive, and the only known specimen of Animantarx was actually discovered entirely remotely using a scintillation counter. It was the first dinosaur to be detected via technology rather than human observation.

(Big ol’ dewlap is speculative, obviously.)

Sorry if this sounds dumb, But is there an easy way to tell Ankylosaurus and Euoplocephalus apart?

It’s not dumb at all! If you’re just looking at those two, the most obvious things are that Euoplocephalus has a more pancake-shaped body and its tail club had two big lobes -

Whereas Ankylosaurus had a more rounded body and its tail was one big lobe -

(note that most ankylosaurs looked more like Euoplocephalus)

Day 29: Ankylosaurus magniventris, “fused lizard”


The original tank from Cretaceous North America! The last seven vertebrae in its tail supported its enormous club and some of its tendons were ossfied (bony) which could create a ridiculous amount of force upon impact. BREAKIN’ BONES, TAKIN’ NAMES.

Happy Easter everyone! And also happy Achillobator day! Achillobator is (in my opinion) one of the more underrated raptors, a giant dromaeosaurid from Mongolia that could have looked a person in the eye. And then eaten them. 

I’ve drawn an Achillobator in the middle of a tense battle with a Talarurus, a large ankylosaur. The Achillobator is making excellent use of RPR (Raptor Prey Restraint) by digging its claws in and flapping its wings madly to keep its balance. Not that it’ll do much good in this case, as the pair of them are about to topple off a small rocky ledge.

This piece has two titles. The first, Tipping Point, is all fancy and artistic and stuff. The other title is Giant Sharp Bird vs. Tankbird, which is … less so.

Meet Zuul, Destroyer of Shins—a Dinosaur Named After Ghostbusters
In 2014, a commercial fossil company was digging for tyrannosaur skeletons in a giant Montana quarry when one of its pit-loaders accidentally bumped into the tail of a very different dinosaur. It was an ankylosaur—a low-slung plant-eater with armored plates on its back, and a huge defensive club at the end of its tail. The company was looking for a tyrannosaur, but it ended up finding the thing that smacks tyrannosaurs in the shins. Read more

((From the same 1992 Godzilla, King of the Monsters manga, here’s Godzilla as a Godzillasaurus! After Doctor Oniyama set in motion his plan to create an Anguirus from a revived Ankylosaurus, he forcibly devolved Godzilla into an unmutated Godzillasaurus for a short time, using KIDS, the time machine from Godzilla vs. King Ghidorah!

After Oniyama further mutated the Ankylosaur into the hulking Anguirus, he used the newly-created kaiju to try and crush Godzilla. However, the devolution wore off and Godzilla rose back out of the ground to begin his fight with Anguirus. As you can probably tell by now, this manga is pretty odd, but in a very fun way!))

((I have recently purchased a copy of the manga’s first volume; the hunt for the second and final volume is on! Expect more scans and posts related to the manga in the near future.))

Geof Darrow’s cover illustration for IDW’s GODZILLA: GANGSTERS AND GOLIATHS #1 written by John Layman with art by Alberto Ponticelli.

Darrow has drawn Godzilla battling the ankylosaur-inspired kaiju Anguirus on Monster Island, which he has further populated with crocodiles and pterosaurs while littering the ground with dinosaur bones.

A huge fan of kaiju movies, I once had the opportunity to ask Darrow if he would ever considering doing a Godzilla comic. He said yes, but only if Toho would grant him complete artistic freedom which he didn’t feel was a policy they were inclined towards since in this particular instance he actually had his work returned to him with a note saying that Toho ask that he redraw Godzilla’s nose since it was not accurate (whatever that means).
