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.

Haematothermia !
Posted Image

So I managed to see the Tetrapod Zoology topic on Haematothermia. The idea was published by a man by the name of Søren Løvtrup, he proposed that "birds and mammals are sister-taxa, united by their endothermy, fully divided heart, respiratory turbinates, and by nerve and vascular characters, as well as others." A major proponent of this is Brian Gardiner, who, with Søren Løvtrup, discussed old observations by John Ray and Richard Owen , which both supported the idea of a bird-mammal group that did not include other tetrapods.
Obviously this is known to be completely false, as we have a wealth of proof pointing otherwise, but I was wondering, what if something like this were true. What if synapsids ended up dominating and producing 'pseudo-bird/pseudo-dinosaur' forms, and that these 'birds' aren't archosaurs, but mammals ! What would this world look like, and how would evolution affect these odd animals ?!

I think both Birds and Mammals would be quite different if that was their ancestor it would also be very awsome.

One of the links I posted was about this same scenario inspired by a post on a blog. Plus I posted some simular concepts.

Hey, what was the last discovered link between synapsids and mainstream diapsids?
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.

I have no idea though I think it was in the Carboniferous.

And why does it seem that when ever I post links they are ignored?
