Species for my Fictional planet, Aurora

Hyparitrix·6/21/2025 in General

I want y'all to come up with some new species for my planet aurora, and why did I come here to do it, yup its filled with dinosaurs and animals that lived with them (Don't ask me how I don't wanna do a yap session)

The species you make can be from the Air, water or land and it does not have to be just dinosaurs, also make it based off of animals from specifically 201 MYA to 66 MYA, and you don't have to draw them. just tell me the name, what family they are apart of, and the range (Optional) (Example: Spinosauridae) welp that's it.

Edit: in making this I already came up with a Megaraptoran that lives in Pseudarctica called "Cryoraptor"

I guess the random chain of land on the left will work.

I might do a different species based off of the animals that get disqualified but for compensation giving them unique traits or locations just so you guys know

Is this a seed world or are they convergent

Hyparitrix·6/22/2025

Can you explain what a seed world and convergent worlds mean?

Harpy Eagle Enthusiast·6/23/2025

Seed world is when you take existing species on earth and place them on a different planet and see them evolve

Convergent evolution is simply this planets species not being from earth but they resemble earth species through convergent evolution

Somewhat unrelated but I am working on a speculative evolution project of my own (species from Earth taken to another planet from 635-2.58 million years ago)

List of extant genera also present on EarthProject Dato Wiki

Granted many pages are unfinished (the wiki is meant to be a placeholder site because I can't really use Google Sites until I get a new laptop since I am aware that many people do not like Fandom)

Dang this planet only has animals from the Jurassic and cretaceous and carth has animals from the Cenozoic (And Triassic of you count Kalemala) so your planet has to be insanely biodiverse

Ornithomimus65·6/25/2025

I’ve suggested two species already, but if I could suggest one more, it would be this guy;

Ornithocursor ornithoi

Ornithocursor ornithomimidae (meaning Ornithomimus65’s Bird Runner) is a medium-sized Ornithomimid, around four or five metres in length. While on the mainland this omnivore is a key prey item for larger theropods, on some of the small islands to the north, Ornithocursor is the top predator, hunting smaller and juvenile species. The only predators they have to fear on these islands are the large Azhdarchids that hop from island to island searching for prey.

They are one of the fastest dinosaurs, running at between 50 and 65km/h, meaning that if you are a small Rhabdodont (like Zalmoxes), it would be hard to escape. Due to their high speed, they require powerful muscles in their legs, which also serve as their primary weapon. When they catch up with their prey, they kick it, which depending on the size of the animal can either stun or straight-up kill it.

They are also extremely aggressive, both on the islands and mainland, to similarly-sized theropods, like Troodontids. They are known to actively seek out and destroy nests of other theropods to both eliminate competition and remove any threats.

Nice

Nice little northern island chain I can work with that

What do you think?
