Liaoningosaurus by Hyrotrioskjan Liaoningosaurus by Hyrotrioskjan
Sooo, this happened.
Rumors about such a specimen were online for quite some time but now it is published and I think many have heard of it already.
I'm speaking about a paper describing a new specimen of the Liaoningosaurus, a basal ankylosaur from China.

The authors of the paper make three extraordinary claims:

1. This species was a predator and ate fish (and maybe other stuff).
2. liaoningosaurus was a semiaquatic animal.
3. The animals found so far are all adults, which would make Liaoningosaurs, with 27 cm, the smallest orinthischian.

This is pretty darn awesome, but unfortunately require extraordinary claims extraordinary evidences.
The paper did in this case not the best job. Many more methods could have been used on the specimen.
Stuff like microwear analysis of the teeth, UV photography, X-ray etc.

I think that all the stuff proposed by the authors here is possible,  and I hope they are right, but the hypothesis stands on weak paws
in the moment.

Because of this I present here Liaoningosaurus not in the most crazy way. We have evidence for juvenile dinosaurs sometimes living away from the adults we also know that they must have been able to swim, just how good remains to be shown. I have some idea how it could have hunted fish but I think it's safer to show it in an more neutral behavior in the moment.
While being more conservative in my approach here the  burrow from which a specimen comes is my little bit of speculation here ;)

More work this animal needs to be done and I'm sure some pretty interesting stuff will await us in the future.

In other news:

The large Theropod paper I spoke about recently was just released, have a look on the "Monster von Minden"!

I think ankylosaurians may have occasionally behaved like hippos.
They have a similar anatomy, and I think Duane Nash pointed out their jaws weren't as derived and good at chewing through tough plants as ceratopsians and hadrosaurs, so I suggest it maybe ate soft water plants ( while Nash proposes dung and eggs...)
Ankylosaurus and Lianoningosaurus both lived in areas with enough water.
So even if this paper turns out be completely wrong, I think Liaoningosaurus still may have been at least slightly semi-aquatic.
Liaoningosaurus also lived alongside Yutyrannus, maybe it was avoiding it by swimming?

Any thoughts and constructive criticism is appreciated.

Ahh die Rekonstruktion gefällt mir ziemlich gut :D
Es wäre wirklich erstaunlich, wenn sich die Theorie als wahr entpuppt, auch wenn es vielleicht unwahrscheinlich ist.

So, without having read the article... I can believe claims 2 & 3, but it will take quite a bit to convince me of 1 because, frankly,

Now, I guess I could see them feeling on shell fish and aquatic arthropods, but I'd be more inclined to believe they would be doing so opportunistically and otherwise foraging off of aquatic plants.

Being adept at swimming or even living near water is not that unusual if one thinks of armadillos, which are actually fantastic swimmers and can even run along riverbeds. This ability comes from their fossorial adaptations (spatulated claws are good for digging and swimming, they can hold their breath which is good both underwater and when digging to prevent dirt from getting in their noses, etc.) Star nosed moles and also forage underwater.

Then there are turtles that both dig and swim... but all these analogues fall short because these are all terrestrial animals with squat bodies, many of whom are armored who only took to the water later (turtles possibly being an exception) where as here sounds like the opposite?

Of all of the things I was expecting to see in the latter of 2016, I never thought that something along the lines of a carnivorous (at the least piscivorous), semiaquatic Thyreophoran (Ankylosaur) would show up. And a very small one at that.

2016 has brought us very remarkable discoveries in the field of Paleontology, yet the year is far from ending.

This is just as amazing and plausible as allosauroids sawing through bones with their super-serrated tongues!

A little, though in terms of locomotion and maybe even feeding style it was more like a alligator turtle.
