create implication titanoboa (99) -> prehistoric_species (72892)
create implication lestodon (1) -> ground_sloth (47)

Reason: Some tags I noticed were missing the implication chain to get prehistoric_species

It seems megatherium doesn't imply it, either, but that's a weird situation. I think giant_ground_sloth tries to be the tag for Megatherium? But it also seems that this tag is often used in place of ground_sloth instead (but it also implies ground_sloth, so both get added at the same time, not sure what's going on there)

create implication palaeoloxodon (1) -> prehistoric_species (72892)
create implication ichthyosaur (50) -> prehistoric_species (72892)

Reason: Cladoselache is a genus of Paleozoic cartilaginous fish. Implying just fish, because even though it's often regarded as a shark it seems to be dubious. Some sources just list it as a chordate, some (like the Wikipedia page linked) list it under Holocephali, which would mean it's closest to extant chimeras. I think tagging it as just fish is safest until/unless that fish BUR goes through.

Cretoxyrhina is a genus of lamniforms from the Mesozoic. I kept the species-specific tag since there are 3 separate species of Cretoxyrhina, but it honestly seems kind of redundant.

Ambient trilobite should be pretty self-explanatory, I hope

Perucetus is a recently described genus of basilosaurid whales from Eocene Peru

Glossotherium is an extinct species of ground sloths

Palaeoloxodon is a species of elephantid with the most recent species believed to have gone extinct 130k years ago, so I believe it qualifies as prehistoric

And Ichthyosaurs are all extinct as well. Honestly surprised they eluded the implication this long, given other marine reptiles have had it for a while it seems

I think I probably wouldn’t do this one. We try to keep 'ambient' species tags from implying any full-fledged species tags since they’re treated more like scenery than characters.

I’ve even considered moving ambient species tags to the general category to drive that point home, but that’s a discussion for another thread…

That's fair, I can remove that specific one. I wasn't too sold on it either.

Reason: Even more that I came across while looking at what implicates reptile

Choristoderes went extinct in the Miocene

Mesosaurs went out in the Permian, so gone for even longer. There also seems to be only a single family, so having the tag be to family and break the naming convention seems unfitting, but I guess that can be done later through an alias request under this forum post.

Claudiosaurus also in Permian

Teleosaurids went out in the Jurassic

Dinosauriforms are a real taxon, and if we want to use it explicitly for the non-bird variation then they'd all be extinct as well. Interestingly enough, whether we have representation of any on the site, though, is a separate thing. According to J. W. Martz and B. J. Small 2019 Pisanosaurus is actually an Ornithischian (this happened 2 years after it was switched to a Silesaurid). So it looks like it should be switched to imply ornithischian instead

Arthropleura is a genus of Paleozoic millipedes from family Arthropleuridae, so Arthropleurids. There currently is an arthropleuridean tag in use, which references subclass Arthropleuroidea but the thing is - Arthropleuridae is the only family in that subclass, so we might as well follow the naming convention and not lose anything

Meganeura is a genus of Paleozoic griffinflies. We don't tag griffinflies, and I highly doubt there'll ever be a post with one that isn't Meganeura, so I think going straight to insect is fine here

Edestus, Helicoprion, and Sarcoprion all belong to the order Eugeneodontiformes, so I think it's fair to group them together. This order went extinct in the early Triassic, so also very prehistoric

Stethacanthus went extinct in the Paleozoic. And to address the common name - it doesn't have one. The term "ironing board shark" is extremely niche. And when I say 'extremely niche' I mean it's used exclusively by a single Fandom wiki and nowhere else as far as I can see. I have never heard of that term before I saw a post tagged as it

Reason: Since the previous BUR in this forum got overlooked I figured I'd just get the next one going instead of waiting

Shenshou belongs to a weird order of mammaliforms that might be mammals or might be cynodonts, but it's definitely prehistoric since it's from the Jurassic

Pelagornis and Osteodontornis both belong to Odontopterygiformes which is a group also called the Pseudotooth Birds alongside a few other names. Since there's more than one species on the site it feels fitting to make a group tag

Eutriconodonts are a group of Mesozoic mammals

And as for the changes to Physeteroidea, I think the tag is indeed useful when other members of the superfamily are counted in (including the extant Pygmy Sperm Whale. I added it here because of convenience, even though it doesn't really fit the BUR). Livyatan and Zygophyseter are both extinct genera of Physeteroid sperm whales. Aliasing the species-specific tag for Livyatan because there's only a single species, so it's completely redundant.

Pikaia is a weirdo aquatic primitive chordate that doesn't really fit any other tags but it's long extinct

Sharovipteryx is a genus of reptiles from the Triassic

Also aliasing away prehistoric reptile since it's pretty redundant and prehistoric mammal has been aliased away already
