Aegirocassis by Hyrotrioskjan Aegirocassis by Hyrotrioskjan
Another quick piece of Paleoart, this time a new gigantic anomalocaridid from the Ordovician of Morocco. With maybe 2m in length it's among the largest members of its group, only Anomalocaris itself reached maybe a similar size. In addition it's the second known filter feeding anomalocarid.

The paper is available here:

Anomalocaridid trunk limb homology revealed by a giant filter-feeder with paired flaps

:) (Smile) Cool. It looks like a fusion of a squid, a whale, and a shrimp.

This is a great depiction of this animal. How would it have swam in life?

Very similar to Anomalocaris probably

Hi! I am wondering whether I can use your Aegirocassis reconstruction for a few blog entries here viventibusesse.blogspot.sk/ and here www.wildprehistory.org/. No commerce is involved and your work will be properly credited. Thanks for consideration! Matus

Awesome reconstruction.  I like yours better than the one from the paper.

It seems that the anomalocaridid were more ecological diverse that we had previously expected, I wonder what other anomalocaridid ecomorphs might be found in the future! 

(I did speculated about parasitic anomalocaridid a while back: the-episiarch.deviantart.com/a… but I don't expect them to be found any time soon - if ever)

Maybe we found already a parasitic anomalocaridid 
but lack the information to recognize it as such. ;)

Speaking of potential anomalocaridid ecomorphs, I spent the weekend reading that Aegirocassis paper and other papers about various anomalocaridids, and I ended up drawing this: the-episiarch.deviantart.com/a…

your welcome. i have a question though, as anomolocarids are not my special anotomical forte, when looking at their digitally drawn reconstruction, these specialize flaps seem to converge at the end, forming an octave, air intake like structure. was it really like this, or am i just fooled by the perspective.

Would be interesting to find out though. I think many planktonic arthropods create a current to pull food in and probably just pick it off their legs. Maybe this one has a closer mouth or more mobile feeding apparatus.

Then again, these creatures surprise science all the time. I still remember when they found one in Devonian strata long after their disappearance from the fossil record in the Cambrian.

I'm still confused that it apparently doesn't group with Tamisiocaris.

:iconhyrotrioskjan:
Hyrotrioskjan Featured By Owner Mar 13, 2015  Professional General Artist
Well, Aegirocassis is obviously more related to Hurdia while Tamisiocaris forms a own group (maybe together with A. briggsi)

Geez, I glanced at this, went to go to the next deviation, and then realized that was a silhouette of a man next to it. I'm not used to seeing arthropods that large haha. What an interesting creature.

Haha, that's how I reacted to the whole story, first thought: "oh do they have more Tamisiocaris stuff" and went on, than I read it somewhere on Facebook again and just saw "2 meters". That's the moment where my pencils become to be involved ;)
