| 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!

Mm well it sounds rather stupid but I'm getting rather confused by it all and I would really like some clarification on a few simple things. Firstly, the most obvious and stupid one: What groups of mammals were around at the end of the Mesozoic - basically, before the K-Pg event? |

supposing that a group of basal fish with 6 fins evolved separately from the basal tetrapods and became 6-member vertebrates ... could they achieve propelled flight? like a dragon (4 legs on the ground and a pair of wings) or something like a biped animal with 2 pairs of wings? I do not know if these bodily plans support flight |

Apparently the most recent known docodonts were in the Early Cretaceous, so unless some even more recent fossils get found we can't include them as examples of mammals from the end of the Mesozoic (also, whether one can even count the docodonts as "mammals" is another issue, as they are outside the crown group mammals). Apart from that, your list seems fairly good. I think the earliest know marsupial and placental fossils are from the Palaeocene, but its likely their origins go all the way back to the latest part of the Cretaceous so that's OK. To your list I would also add eutriconodonts, gondwanatheres, dryolestoids, non-marsupial metatherians such as the stagodonts, and non-placental eutherians such as the cimolestans. If we're using "mammal" to refer to more than just crown-group mammals, then we could also include the haramiyidans, a group of mammaliforms that survived up until the end of the Cretaceous. |

Did dicynodonts (and other advanced non-mammalian therapsids) produce milk? (Like platypuses?) Would it be safe to assume that they did? |

milk or something close enough to milk, that only a specialist would quibble over if it is or not. |

Is there any reason why poisonous reptiles (specifically lizards) haven't evolved; using the toxin as a defence tactic? And for clarification I mean as in the animal has toxins in its skin or body that would make it dangerous to eat and not venom it uses to inject into prey. |

This is coming really late, but there are reports of parthenogenesis in birds. This source (pdf) mentions it in chicken, turkey, pigeon and zebra finch. It's extremely rare and "almost always abortive", but it happens. |

How relatively easy is it for amphibians to evolve resistances against chytridiomycosis caused by Batrachochytrium dendrobatidis or related/similar disease causing fungi? |

Is there any way I could get copepods to fully terrestrialize? They lack a heart, gills and any kind of circulatory system. Oxygen just passes through them because they are so small. But this wont work for a fully terrestrial animal.
