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.

Very crude attempt at figuring gorgonicthys. A placoderm similar in size to dunkleosteus with even larger shearing blades

Dunkleosteus terelli, an Orca Sized Placoderm that roam devonian sea.

Dunkleosteus doesn't have any teeth. Instead, it's an extended of it's lower and upper jaw that acts like a teeth.

an old reconstruction of the Early Devonian placoderm fish Lunaspis. Named for how its spines resemble a crescent moon 🌙

The preserved heart of a ~380 million year old placoderm!

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.

from 2017 for the giant placoderm Titanichthys filters through Devonian seas. This image is featured in my old school "tour-through-time" 2020 book Life Through the Ages II. I had a blast putting LTTAII together, I hope to something like it again someday.

For the end, I mix a Placodermi and Amou Haji to make a new character

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

Bungartius

An odd placoderm, its related to dunkleosteus but not as closely as it was once believed, its easily recognized by the odd shape of its jaw

ALT: besides its spear like chin its mouth has been compared to a staple remover, with two pairs of sharp blade like teeth

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

Dunkleosteus terrelli

(Based on the edited skeletal made by Tyler Greenfield)

Brindabellaspis

A basal placoderm that seems to be closely related to modern jawed bony fish, and even shares some similarities with basal ostracoderms

ALT: A notable thing about this creature is its elongated snout, which some have compared to that of a platypus

3 24

Lunaspis

A flat ray like nektonic placoderm with wing like long pectoral spines , it also had small scales around it eyes nose and trunk

ALT: its named after its long pectoral spines, that make it look like a crescent moon, and also make it look relatively similar to a skate

2 23

Gemuendina

A mid sized placoderm with a size ranging from 30 to 100 cm, it was similar to modern rays but with its face on top of its body instead of under

ALT: its armor was relatively frail being made of a mix of plates and scales, which made fossilization difficult
