| 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. Join our community today! |

This might have been superceded - I refer back to "Kadimakara". a book about Austrailian paleo-fauna (Kadimakara - Extinct Vertebrates of Australia - by P V Rich, G F Van Test and F Knight - copyright 1985 ISBN 0 909674 26 4) Page 259 : Rhabdosteidae Class: Mammalia Infraclass : Placentalia Order : Cetacea Suborder : Odondoceti Family : Rhabdosteidae Genus and Species : Indeterminate (at present - copyright 1985) Age : Middle Miocene Fossil found Lake Frome South Australia, 1971. Only known from fossils of ear bones - perhaps in the interim they've been re-classified? Australia also had populations of large robust flamingoes. |

Well, ceteacean ear bones are unique, so I suppose it IS a cetacean. |

Porpoises aren't the smallest cetacea. The shoulders would pop out if a dolphin/porpoise tried to drag itself; that's why a whale too small to die under its own weight can't save itself. |
