#placoderm

[knuppitalism-with-ue]

On yesterdays #paleostream we covered the Gogo formation, a diverse assemblage from the Devonian of Australia. It is an extremely productive formation with high levels of preservation, giving us stull like the oldest preserved heart and placoderms mid birth.

Gogo is one of these places though where "formation doesn't equal ecosystem" holds true a lot. In this case not because the animals were preserved over a very long time span but because the formation doesn't at all reflect where these animals lived.

The Gogo formation is a bunch of little hypoxic (low oxygen) basins in which the carcasses accumulated and were preserved in hard concretions. They lived however in and around the reefs that surround these basins.

These reefs formed massive limestone platforms that can still be seen to this day. They were build largely by stromatoporid sponges of the genus Actinostroma. However on the edges of the reef we also have colonies of corals and that's where I wanted to set this piece.

As a reef community, most stuff from here isn't that large. As you can see in these size charts by Discord member JW, the largest diversity can be found in the placoderms but funnily enough some of the largest animals are actually phyllocarid crustaceans.

Deep in the ancient oceans, lurks the mighty Dunkleosteus. A bit of Blockbench paleo art from a little while back i never posted.

Based on the recent, more rotund, reconstruction of D. terrelli, still quite the fearsome beast!

Been some time since i did any paleoart so it was great to finally get back to it again!

Let me know what you think!

piece i submitted for a public art exhibit last month but it wasnt accepted

AUGHHHHHHHH WHY DID PLACODERMS GO EXTINCT WHYYYYYYYYYYYYYY!!!!!!!!!!!!!!!! WE COULD’VE HAD AN ALL UNIQUE GROUP OF FISH AS WONDERFUL AS CARTILAGINOUS FISH AND RAY-FINS AND LOBE-FINS!!!!!!!!!!!!!!!! BONE TEETH APEX PREDATORS COULD’VE BEEN OURS TO SEE!!!!!!! WE SHOULD’VE BEEN ABLE TO SEE HER AND PET HER!!!!! I SHOULD’VE BEEN ABLE TO!!!!! IT’S NOT FAIIRRRRRRRRRRRR

What is the best fish, and why is it Dunkleosteus?

Because everything about it is perfect.

Results from the last #paleostream of the year!

Acheronauta, Diatryma, Hadrosteus and Imperobator (wing mobility is rather speculative).

Hello Paleo Tumblr artist or something

I love the dunkleosteus!! One of my favorite placoderms😁

Made a hairionette one lol!!

Bothriolepis

Oh my god I love and hate this thing why does it have so many species

Anyways my opinions aside, this guy is a male and he’s migrating upstream for a reason

I don't only draw dinosaurs

It’s been quite a year since Dunkleosteus terreli, the 4.5-meter-long King of the Placoderms that had the most powerful bite force of any fish living or extinct, made news with to this groundbreaking study:
