Well, next best thing is to engineer a similar critter from scratch.

You sure there would be enough of demand for effort to be put into recreating these?

[JustaDumbThriver (He who has the IQ of a half-eaten Wendy's Baconator(tm))]

No, unfortunately… Electronic recreations are the best bet for now, you know, a fake Sidneyia to decorate your fish tank or something? With like, motor legs. It won’t be AI, but will just have to have the legs vibrate or something to swim.

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

It’d need to have a battery case so that it’s energy can be replenished.

[JustaDumbThriver (He who has the IQ of a half-eaten Wendy's Baconator(tm))]

Yeah, that too, of course.

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

And how did you find out about this critter?

Would plushies be better? For example, Paleozoic Pals.

I can assume that’d work for pretty much any animal one can imagine from that period…

[JustaDumbThriver (He who has the IQ of a half-eaten Wendy's Baconator(tm))]

Why can’t we make a change.org petition to make a sidneyia plush?

[AnthropocenianAge (𝒜𝓇𝓉𝒽𝓇𝑜𝓅𝓁𝑒𝓊𝓇𝒶 𝓌𝒶𝓃𝓉𝓈 𝓉𝑜 𝑔𝒾𝓋𝑒 𝓎𝑜𝓊 𝒶 𝒽𝓊𝑔!)]

Apparently, someone made a piece of music named after Sidneyia.

By the way, what do you people in here think Spriggina was?

[JustaDumbThriver (He who has the IQ of a half-eaten Wendy's Baconator(tm))]

Probably just some worm not related to any living phylum.

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

And related to the extinct group of Ediacaran critters I presume?

[JustaDumbThriver (He who has the IQ of a half-eaten Wendy's Baconator(tm))]

Yeah, might be just an extinct Ediacaran group. The most specific group we can put Spriggina in is either Deuterostomes or Protostomes, but beyond that is no real basis. All we know for sure is that it was Bilaterian. Who knows, maybe it was a stem bilaterian?

[AnthropocenianAge (𝒜𝓇𝓉𝒽𝓇𝑜𝓅𝓁𝑒𝓊𝓇𝒶 𝓌𝒶𝓃𝓉𝓈 𝓉𝑜 𝑔𝒾𝓋𝑒 𝓎𝑜𝓊 𝒶 𝒽𝓊𝑔!)]

I thought it had glide symmetry and was not a true bilaterian?

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

Yeah, was about to ask about that.

[JustaDumbThriver (He who has the IQ of a half-eaten Wendy's Baconator(tm))]

Maybe it was an intermediate between asymmetry and bisymmetry?

[aah31415 (The maker of SitF, Radiostrocity, The Lifenote and TGBing; The Second Ascended...; And just maybe a security warning come alive...?)]

Aren’t these thought to be step-animals? Though I suppose this could have been a rival symmetry to bilateral at that time.

[AnthropocenianAge (𝒜𝓇𝓉𝒽𝓇𝑜𝓅𝓁𝑒𝓊𝓇𝒶 𝓌𝒶𝓃𝓉𝓈 𝓉𝑜 𝑔𝒾𝓋𝑒 𝓎𝑜𝓊 𝒶 𝒽𝓊𝑔!)]

So glide symmetry?

Also, I found a link that lists Precambrian “Arthropods”.

Tbh most claims on arthropods before cambrian are rather dubious.
