A swampy shore with a wide shore, rudely occupied by a group of croaking Tiktaalik. A couple of placoderms shift through the muck like carp. looks incredibly humid inside.

Warm-up doodle, prompt Plausible Pokemon. Steelix is evolved from slithering Placoderms that eat enough iron-rich prey for their bone armor to become enameled with shimmering steel. Said armor has fused the fins, which are sharpened against stones.

So in a new update of old paleo recons I bring one of the most unusual giant placoderms, Heterosteus, which is known by varied fossil fragments and considerable material, exposing a large sized animal for its time.

Found this figure in a paper about the first evidence of claspers in placoderms
The Devonian must have been a wild time

Bianchengichthys micros, a new maxillate placoderm from southern China described by . It, along with a few other placoderms, suggests that the origin of all eugnathostomes might be from Vietnam and southern China.

Stensioella

Possibly one of the most basal placoderms, its strange elongated body makes it hard to determine its relations, some think it might be related to chimaeras instead

ALT: similar to gemuendina its armor is like a mosaic made by small scale like tubercles

Bothriolepis

A placoderm found all over the world, its size ranges from 30 cm to 1.7 meters depending on the species

ALT: Some specimens have retained soft tissue, one had organs that could be homologous to lungs, however there's no proof of actual lungs in placoderms

06. Describe Your Character Creation Process
I'll have a list of character traits / reference images that I'll try to make sure are reflected. E.g Gummie was sarcastic and abrasive so I tried to get that across meanwhile for Perfect I had a bunch of ref images of placoderms.

Antarctaspis

A placoderm found in the Lashly mountains, not much is known about it since the type specimen is known only by a partial head shield

ALT: similar placoderms have been discovered in Australia but its unknown if they represent the same genus or distinct genera

I’ve missed the last couple of challenges. I was still short on time really didn’t want to miss a 3rd; especially when the brief was

you could give some love to ostracoderms, only earth archives has given them any love and eons had them in the same video as placoderms so of course they got overshadowed by dunkle, idk if it could give you enough content tho u.u

Speculative parasitism in prehistory:
- Parasitic radiodontids
- Parasitic trilobites
- Cleaning symbiosis in placoderms
- Condonts infected with tapeworm larvae

PLACODERMS ARE BETTER THAN YOU
here is why..

In humans if our spine fuses its hella pathological, and can be completely debilitating

In their back bones fuse as part of their physiology.

Its just a part of growing up dunk.

Yeah the gnathal plates in placoderms are derived from teeth that grow outwards in in a ring instead of in rows
They also have the same structure as their scales proving that teeth evolved from scales
