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.

What if some sort of disease wiped out early dinosaurs such as Coelophysis during the late Triassic, what kind of creatures would have evolved in their absence?

Dinosaurs eat man, woman inherits the Earth.

Pterosaurs might've.

Some marine reptiles could have taken to land again.

But most likely, mammals would have started their reign early.

It would have been very interesting to have a Pterosaur dominated Mesozoic, with mammals tagging alongside them !

Crocodillians will have a field day at 1st and perhaps form an unheard of diversity of Herbivores, Omnivores, Carnivores and certain aquatic niches. Of course after this initial dominance I see Mammals and Pterosaurs growing in dominance until Pterosaurs are the top predators and Mammals have niches within the niches of Dog to Rodent sized niches. The Crocodillians will still keep a bunch more niches than they have on our world though.

I see many of the larger animals going extinct in the K-T but I don't think it will be as bad since most of the animals will be smaller and require less resources during the extinction allowing more to survive on the low resources.

A consiquence I see happening is the extinction of Placentals and possibly Marsupials since they seem to diversify into larger niches quickly which might cause them to die during the extinction by expanding into large niches in the Mesozoic. What this means is that there might be Multituberculates and Monotremes ruling the Earth presently, unless they stay in niches close to their Earth counter parts in which case the world is ruled by Pterosaurs and Crocodillians making this the Age of the Archosaurs.

How come when I made a topic like this almost no-one was interested, oh well.
Protosuchians and Sphenosuchians would go alright I think.

Why does a sapient azhdarchid need to be flightless? Why not a sapient flying azhdarchid?
My speculative dinosaur project. With lots of fluff, parental care and mammalian-level intelligence, and the odd sophont.

It would be like:

Crocodilians and Kannemeyerids rule this world. Coelophysis dies/never evolved, and Crocodilians took their positions. Kannemeyerids and other mammal-like reptiles still became extinct because of the lack of food and water. Crocodilians terribly decline due to the lack of prey. Most food chains colapse, and mammals and pterosaurs take over.

True, I've always imagined my sapient pterosaurs as flighted

Taking off, flying and landing use up a lot of brainpower. That siad, humans became so sapient as they freed up parts of thyeir brain tied up in sensory stuff and co-ordination.

If you want reptile sapients, they would have to be very erect (like a maniraptoran style erect) and have really big heads. They would need much bulkier bodies and limbs, and their tails would have to thicken.
Time flows like a river. Which is to say, downhill. We can tell this because everything is going downhill rapidly. It would seem prudent to be somewhere else when we reach the sea.
