Hermit Anomalocarid by NocturnalSea Hermit Anomalocarid by NocturnalSea
A hypothetical anomalocarid and its equally hypothetical commensals. First in a series.
Here I've postulated a group of anomalocarids that have developed a hermit crab-like habit of using discarded shells (in this case a Hercoceras nautiloid) as protective homes. This specimen is the Blue Squid-crab (Repticaris caerulea), a benthic animal that drags itself along using its first two sets of highly-modified lateral fins. Like Atlantic lobsters, the squid-crab is an opportunistic feeder, typically scavenging carcasses-- although it will occasionally catch live prey such as this Weinbergina opitzi (a real prehistoric animal and a relative of the horseshoe crab).
The squid-crab's shell also provides shelter for several other animals. Coin trilobites (Harpes denarius) live just inside the mouth of the shell, emerging occasionally to scavenge scraps from their host's meal. A boring sponge (Archaeocliona xanthos) often colonizes the upper parts of the shell. It's acidic burrowing frequently breaks all the way through to the interior camerae, providing shelters for the poisonous, brightly-colored trunk-squid (Cryptomonstrum nothopabinia), a relative of Tullimonstrum gregarium.
In addition to the speculative animals, I've also depicted here a couple of real-life prehistoric critters. The squid-crab is currently trudging through a forest of crinoids, composed primarily of Hapalocrinus and Bactrocrinites. Edging the open areas of the forest are several conularids and an abundance of edrioasters and seastars. Finally, in the upper right corner is the crinoid-eating pycnogonid Palaeoisopus.

hi, nocturnalsea, nice anomalocarid.im so curious, what's species of that flying slug thingy with light blue, orange (or red), and black?

Well, it's actually a hyothetical animal. The body is based off of Tullimonstrum gregarium, an unusual prehistoric mollusk found in fossil beds from Illinois. The color pattern is based off a sea slug, Thuridilla lineolata.

...mollusk?

well, Tullimonstrum's affinities aren't exactly known, but it most closely resembles a mollusk-- specifically the sea elephant, Pterotrachea coronata. Here, have a look: [link]

That is such a cool idea, and the way you've integrated it into its environment makes it seem so *likely*. When something like this is actually discovered, those of us in the know need to proclaim "Nocturnal Sea called it!". You make the crinoid forests look like a badass place to go time-diving....

Wow, thanks for all the kind words! I think I might have mentioned it somewhere else, but the original idea for all these hypothetical anomalocarids was sparked by the discovery of Schinderhannes bartelsi. I mean, anomalocarids were supposed to have died off in the Cambrian, but all of a sudden here's this one lone fossil in the middle of the Devonian. That means there were hundreds of other anomalocarid species preceding it (and possibly appearing later as well) that we just haven't found yet.

Devonian. The real animals are from the Hunsruck Slate laggerstatten.

What a freakin' AWESOME idea...I've considered many possible variants on the (alternate and/or prehistoric) "hermit x" theme, but never a "Cambrian hermit." :omg: Fantastic concept, and a sublime drawing!

What about a vertebrate hermit? Some kind of highly-modified shark, maybe?

thomastapir Featured By Owner Mar 19, 2011
I think the farthest I ever got with the vertebrate end of it was ([link]). Shark is a cool possibility! An idea I've had in mind since '09 is a sort of "hermit eurypterid," then evolving into terrestrial and eventually shell-less arboreal forms paralleling the coconut crabs.
