Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike. With a member base comprising users from across the world, our community is the largest and longest-running place of gathering for speculative biologists on the web.

While unregistered users are able to browse the forum on a basic level, registering an account provides additional forum access not visible to guests as well as the ability to join in discussions and contribute yourself! Registration is free and instantaneous.

Mostly issues involving a the conundrum of a hard shell.
I don't recall if it actually applies to all archosaurs, but for one example, I'll use birds.

All extant birds, regardless of size, diet, or lifestyle, all lay eggs with hard, calcium-rich shells. The issues of getting around the egg mostly comes from said shell: the baby bird needs the calcium in it. Other issues crop up as well, particularly the transitional stages from egg-laying to live-birth: case in point, ovovivparity. The egg stays inside the mother until after the egg has hatched, like in certain frogs and sharks. Birds can't currently do that, since the proportions of their eggs would prevent whole clutches from staying inside and the sharp fragments of shell would prove dangerous.

Apart from Shringasaurus (very similar to the horned iguana from the 1960 version of The Lost World) and filter-feeding anomalocardidids, are there any other extinct fossil animals uncannily similar to fictional/speculative species made up before them?

Scansoriopterygids using their elongated 3rd fingers to support a patagium was thought of before Yi had been discovered, if that counts.

Several of the animals from “The new dinosaurs” like the Zwim.

In addition, I would like to know exactly what fictional species the filter-feeding anomalocardids are similar too, as I don't remember.

John Meszaros drew a filter-feeding anomalocaridid for All Your Yesterdays a year before Tamisiocaris was announced.

Would it be too implausible for a chemosynthetic cyanobacteria to produce oxygen as a by product?

Cyanobacteria are photosynthetic you mean other types of bacteria?

Let me rephrase.

Are there any chemosynthetic, non-photosynthetic, extremeophile Bacteria or Archea that produce oxygen as a by product?

Could animals that have lost parts of their body (Snake limbs, Bird and Ape tails ,ect) 're-evolve' them?

Could a moon orbiting a warm tropical planet be mostly cold and icy? Assuming the main reason for the planets temperature is atmospheric gasses, not just being very close to its sun.

Yeah if the cause for the planet's temperature was largely due to the atmosphere, then the moon can be cold and icy. Moons are pretty much far enough away that the atmosphere or temperature of the planet has p-much 0 impact.

Yes!
A lot of the time when an organism loses a body part through evolution, the genes coding for that body part are still there. The genes just aren't turned on. While it isn't as simple as hitting a switch and having a whale grow legs, this means that if the selective pressure is there and there isn't a simpler evolutionary solution an organism could potentially regain a body part that it's ancestors had.

Yes, it's certainly possible; it's not exactly a simple genetic change though, the likelyhood of it happening it probably quite low.
totally not British, b-baka!
