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.

Interesting, do we have any proof that Ammonites were little squid things? I remember when I was much younger a book saying we've never found any fossils of their soft parts.

From what I can gather there are soft tissue impressions that show that they were not only squid things, but more closely related to modern day squids and octopuses/pi/R'hylleh than to the other shelled cephalopods.

Now THIS is weird! I have trouble imagining a cephalopod making perals. I wonder if all ammonites do this or only a couple?
