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.

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.

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.

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

Incidentally, cleaner wrasse was my inspiration for this speculative zoology piece on "Cleaner Placoderms" https://t.co/OcIS9SYZJV about how some ecological interactions we see today might have also existed in the ancient past
