A submission awaiting review, the Copperspike, is a microbe that uses heat for energy. The basis for this novel metabolism is a piece of information in the page for the Protohydroia Octherma, the ancestor of its ancestor: "It gets its energy from these as well as the geothermic heat given off from the vents and hot springs."
However, a quick check suggests this kind of metabolism would be difficult for an individual microbe to have. The source suggests it would be easier for a colony to accomplish, but there are still plausibility issues.
One option is retconning the Protohydroia Octherma to make using heat for energy more biologically plausible, while another option is eliminating that part entirely. None of its canon descendants use heat for energy, so eliminating that part entirely may be the easiest solution.

Volcansheet is an organism that is listed as a thermotroph (& lithotroph)
Volcanic Voltflora are also listed as Thermovore.
"These organs convert the heat from the volcano into energy"
The Southern Rustcell is also described as "It is most often underground, and so has lost its ancestor's "thermosynthesis" Ancestor: Thermomold
We have three different names for the same basic process. Which messes with things a lot.

This is more of an elaboration and clarification than a retcon concern, but, nonetheless, this is an issue for the Warf Gossalizard and its descendants.
As pointed out here it's unclear to what degree descendants of the Warf Gossalizard are endothermic, and how this endothermy is maintained.
The Hairy Gossalizard, while not noted as endothermic, has "proto-fur", which is mentioned as a cold adaptation, and stores fat in times of famine. The use of fat might be a clue on its metabolism.
The Warf Gossalizard is "slightly warm-blooded", has a fur-like integument, and lives in a tundra environment. It's not impossible for an ectotherm to live in the tundra, particularly if the planet's overall climate is warm, but in cold conditions it would require special adaptations, such as antifreeze compounds.
One of the descendants of the Warf Gossalizard, the Desert Gossalizard, retains its status of being "slightly warm-blooded", although it lives in a warmer climate and has less fur-like integument. That it didn't revert to ecothermy when it theoretically could have in just one step might suggest endothermy had been fairly well-developed.
(This might be a useful source.)
By the submission under review, the Turquoise-Helmed Lizalope (if not earlier) it seems likely strong endothermy had been developed. Turquoise-Helmed Lizalopes are specialized for "running faster and longer" (relative to their ancestors) and are always on the move, and seem to eat constantly. Sustained activity like this in colder environments suggests endothermy.

I've been working with the assumption that ovi's gossalizards are endotherms. It makes sense for them to be at this stage.
Hello, apologies if I do this wrong, but given the issues with early iron fauna, I was tasked with making a descendant of the Ferrumworm that was a shared ancestor between the Ferrumvac, Snyron, and Irondigger (the latter a retcon) in either Gen 91 or Gen 92. Here is my wip, let me know what needs tweaking, and my apologies if I explained this poorly.
Ferrumfeeder (Orispedis dragma)
Creator: Changeling
Ancestor: Ferrumworm
Habitat: Ittiz-Ovi Desert, Ittiz River, Ittiz Swamp
Size: 5 cm long
Diet: Lithivore, Detritivore, Planktivore (Crocusium, Ciliognathus, Luminuseven, Saganchaos, Chlorocytus, Megaorthoceros segnoneustes)
Respiration: Semi-Active (Siphons)
Thermoregulation: Ectothermic
Support: Exoskeleton (Hematite)
Reproduction: Spawning, Hermaphrodites
Some of the Ferrumworms in the Ittiz watershed have adapted further to this terrain, as their specialized cells that were used to magnetize metal that been repurposed. Over generations they began to grow into twelve hollow muscular tubes, partly made of hematite as well as cells. These tubes can be used to drag the Ferrumfeeder across the seabed, but also are each effectively a mouth as well as a breathing apparatus. While they continued to eat iron, they have begun to filter feed on the microscopic life of the river and swamp, as well as loose detritus and mineral deposits.
As the Ittiz River flows within a desert, they have adapted to aestivate in a burrow when the dry season comes. When the water rises their nostrils will detect the reemergence of plankton blooms, and will crawl back out to resume feeding.
If they are cut in half, it’s possible for both halves to regrow and survive. They will not be able to fully form an adult Ferrumfeeder, and the half with nostrils has a better chance of survival, but they can occasionally last long enough to spawn. Spawning is its main method of reproduction: its ability to regrow from roughly half its body is more useful in ensuring it has time to pass on its genes than a true form of reproduction.

The "Description" at the beginning of the description should be omitted, and there should be a paragraph space between the template an the start of the description.
"spawning is their main method of reproduction," The comma should be a colon. I recommend using "its" for this sentence, rather than "their", as "their body" is confusing.
Otherwise, I lack sufficient knowledge on the lineage and this time period to say anything.

| So uh, any updates on this? |
Well?....
Moderators have a lot of tasks to attend to: this might not be considered especially urgent.
Alright, so I think the ferrum feeders looks good. Anyone else got any comments on it?...

@Disgustedorite and @MNIDJM thoughts on this one Ironfauna? It helps resolve the phylogenies of several Ironfauna groups while also settling why several of those groups feed with their limbs rather than through mouths.
