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.

I'd recommend against that. Projects based on preexisting works of fiction tend to go poorly, since it's basically impossible to balance realism with faithfulness to the original work.

Since that show is very peculiar in designs and settings,i can gladly say that a short spec could go well.

IDK but somehow i seen around few spec revolving around fictive settings.

Birds are Theropods, but Ornithischians are named after having bird-like hips, so are bird hips different to other Theropods? or do Ornithischians have hips that are similar to all theropods?

Ornithischians got the name "bird hips" because one of the three bones in their hips, the pubis, points backwards and sits against the ischium, like in modern birds, while theropods and sauropods had the standard condition of the pubis pointing forwards instead, like this:

This dichotomy for trying to classify dinosaurs completely breaks down though because a number of theropods, especially the maniraptorans, evolved backards-pointing pubises independently of ornithischians, and modern birds inherited this trait which is why they have the "bird hip" configuration in the first place.

The whole Ornithischia/Saurischia name mess is a great lesson in why it's best not to get hung up on what names mean in taxonomy. It helps sometimes if the names are accurately descriptive of whatever they're for, but then you get situations like this where birds aren't "bird-hipped dinosaurs" but they kind of are because they have the "bird hip" configuration and have bird hips either way because they are birds with hips.

Where dissophorid amphibians fully terrestrial, at least as adults? Do we know if they laid eggs in the water or not?

Those hip bones look like warped dino heads.

I would imagine they'd be ecothermic like all other true crocodilians.

Can all marsupials have a few young at one time (one in the pouch, one developing in the womb and another as a fertilised egg that is suspended) or is that just exclusive to kangaroos?

Well, many marsupials can have more than three young at a time, but I know that's not what you are talking about. Most macropodids are capable of embryonic diapause (although a few don't), but it is little studied in other marsupials. The Honey Possum has been found to be capable of diapause, and it is probably present in several other marsupials as well. Several other mammals are also capable of embryonic diapause, but it is most famous in macropods because of the cycle of one joey at foot, one in the pouch and one in the womb that no other mammals are capable of.

Do tadpoles have bones? I feel like they would, being baby frogs and all, but wikipedia said that they have no hard parts that easily fossilize, and I couldn't find a clear answer elsewhere.

Just to be clear, I am only referring to the larval stage of frogs and toads. I am well aware that the adults have bones.

Technically, most lack true bones. They instead have skeletons of cartilage. This is true even of some adult frogs, especially small South American species.
