Fukuisaurus, Cartorhynchus, Nanuqsaurus and Stethacanthus

I quite like all of these, though the Fukuisaurus needed some touch-ups afterwards. Stethacanthus is a little goober :3

Bonus trans Stethacanthus:

My 25 years of palaeoart chronology...

In 2010 I painted the Early Carboniferous shark, Akmonistion zangerli hunting Acanthodes fish. This was for Matt Dale and the famous Mr Wood's Fossils, in Edinburgh, Scotland: https://www.mrwoodsfossils.co.uk/

Akmonistion/A. zangerli (Formerly Stethacanthus)

Name meaning: “akmon” = “anvil” & "istion” “sail” (both Ancient Greek) Lived from: 330-323 million years ago Stage/Age: Serpukhovian Epoch: Mississippian Period: Carboniferous Location: Bearsden Scotland Discovered by: Stan Wood Discovery date: 1982 Family: Stethacanthidae Genus: Stethacanthus Domain: Eukaryota Class: Chondrichthyes Order: Symmoriiformes Diet: Small fish and arthropods Akmonistion was a 60cm long shark with an anvil like specialized first dorsal fin called the "spine-brush complex" which is similar to the thoracic shield in placoderms and postparietals in catfish. This dorsal fin would've made it that the Akmonistion most likely couldn't swim fast. It is not confirmed what exactly the function of the spine-brush was but was most likely used to either used to scare away predators, attach to other large animals like a sharksucker, to mate or attract a mate. Its other dorsal fin is made of parallel rods with roots that have sharp ventral tips buried deep into it's skin. The Akmonistion was most likely a bottom feeder because of its small fins and teeth. The Akmonistion also had relatively large and had a pair of whip-like pectoral fin extensions possibly used during mating, with the male pelvic fin having a pair of pelvic claspers.
