Lamna gave me an interesting idea for the fauna in Britain and presumably in the Atlantic island ridge and mainland Europe as well: the presence of marsupials. Britain already has introduced wallabies, and if they survive they could diversify in the isolation of the British Islands. Because large herbivorous niches are already held by deer and boar descendents I think several other interesting paths of macropid evolution will take place in Britain; maybe tree climbers will evolve, taking monkey like niches in the forests of the warmer Britain of the future, and resembling tree kangaroos and cuscus via convergent evolution. Additonally, some forms could take the marshes and swamps, becoming swimmers akin to herbivorous yapoks. Besides kangaroos I invisioned some american marsupials reaching Britain after their diversification in the Caribbean and crossing the Atlantic thanks to the Atlantic Island Ridge. The ancestors of these would probably be otter like forms that colonised Ireland; if they manage to co-exist with freshwater otters than maybe they could manage to expand, and maybe some return to land as oppossum analogues living in the trees |

i dont believe that marsupials could survive in europe-they are from small number of specimens(inbreeding) and due to inbreeding there are common some genetical problems,like albinism...now they numbers alre too small to they can be succesful - maybe only 70 specimens in small colonies |

In war, victory. In peace, vigilance. In death, sacrifice.

Well there will always be a slow trickle of new blood from escaped captives. Plus they are becoming more popular as pets |

they propably go extinct in next ice age if they arent extinct now http://en.wikipedia.org/wiki/List_of_mammals_of_Europe Edited by Bexi, Apr 10 2010, 04:09 PM.

I wonder how they'd be affected by some of the British animals I created. |

I like the idea of British wallabies. That's why I have walking wallabies in Europe in the Postozoic. |

Moguar, Wyrmfish, Greenback Baronander. I attempted to put in the Great British Water Slider. Couple of other ideas, mostly shot down. |

Well, if the wallabie ideas get shot down at least I have the more recent immigrants from the Atlantic islands |

how the marsupials get to atlantic islands? |

Jumping first into the Caribbean, then as the atlantic island chain forms they reach them, first perhaps under aquatic forms akin to the yapok. |

i think that aquatic forms of marusupials dont get succesfull,placentals is better adapted,there is only one form and species of aquatic marsupial and big number of placentals..maybe there can go forms like opossum |

Well, I consider the yapok the first step. Fully aquatic marsupials are quite possible, I just don't consider them specialising to a fully aquatic lifestyle, though freshwater amphibious predators might diversify. But yes, opposum like critters are enough, provided they end up in natural rafts like lemurs and the ancestors of the new world monkeys did |

wow ( off topic here) johnfaa is more open minded now. last time this topic came up johnfaa prettymuch just shot me down in flames when i pointed out the exact same thing as bexi. and about the otter marsupials. i think they could colonise the rivers seeng as otters in europe are endangered now and might g extinct although they could have repopulated by the time marsupials get over there, though they might not have |

i think that otter,seal niches will be taken by carnivores (mustelids,civets..) european metatherians will be propably same as today north american-unspecialized,opossum like |
