Artober 2026 but it's the Permian period - 06: Xenacanthus

A freshwater shark. What was the spine for? We're not entirely sure - maybe it was venomous?

Yeah, the xenacanthus with a sword on it's head.

did a retake of a shot i took ~6 months ago now that im starting to get a hang of lighting, i thought this spot would be great practice! here's the original vs new:

ultimately this comes down to taste, but im happy with the improvements i made! i hope xenacanthus approves 🐟

i also made this shot into a video (my sneaky ultimate goal - i needed a cozy fall wallpaper for my pc), so feel free to take a break by the water for a bit; xenacanthus won't mind some company 🍂🍃

Xenacanthus ✏️

I saw a model of this prehistoric shark in a museum a few months ago and wanted to draw it- finally got around to it recently.

ive gotten quite a few bites on lopoceras too but its about as slippery as xenacanthus so its def going to take quite a few windows.

yeah this was the first one i really felt like the lures made a HUGE difference i'm interested to see what else will feel like that (xenacanthus also feels significantly easier to get chances at tbh)

It was the top predator in its ecosystem preying on various tetrapods, amphibians, and the freshwater shark Xenacanthus (which may also have preyed on smaller Dimetrodon.

Some skin impressions of the tiny D.teutonis shows the underside at least had scaly skin similar to reptiles.

I may owe Megalodon: The Monster Shark Lives an apology, at least that one taught something

Nah for real, this is certainly a new low for genAI in documentary media. Here, have some REAL sharks (including some prehistorics!) I drew for 2023's Shark Week.

Do better.

how much do I love the Permian?

I wrote an entire TTRPG setting with 2 adventures in it about magical, talking Permian critters: ulemosaurs, dimetrodons, nautiloids, and xenacanthus sharks o my!

I was asleep for half of it so I just went and caught Furcacauda and Xenacanthus again for funsies. 10/10 fishing day.
So we heard there was some legendary fishing over the weekend 👑🐟

How many did you catch?

Xenacanthus? Long green legendary with horns...
October 22, 2025 at 5:29 PM
I have this one. Love it. :) It confidently tells us that Stegosaurus flattened its plates down as a defense mechanism, and that it probably then curled up like a hedgehog. Glorious aquatic Brachiosaurus too! Check out Xenacanthus in the back, though. I adore that painting.

I love fishers 😭 she walked up to me and cheered and I cheered back
March 14, 2026 at 5:42 PM
A lot 😭 knock some down only to continue to get flipped off by Xenacanthus
I feel like that fish exists just to torture me

The model for that other one is on the way, but for now, here's another random fusion. Xenacanthus (yes, another prehistoric fish), fennec fox, and monarch butterfly.
