Greetings. : )
@Gec: I've heard of Sagan 4, but I haven't worked in it...
@Yuu: Some of them are. What I'm working on is somewhat based on part of an incomplete
fanfic I wrote. The yet unnamed planet is supposed to be similar to earth, but with a bit cooler climate and more trees (mostly resembling Alaska, Canada, the Northern United States, and parts of Russia, but warmer around the equator).
So most of the animals will be adapted for colder climates. The penguin thing's appearance and behavior were inspired by elements of penguins, killer whales, elephant seals, and Liopleurodon (as seen in walking with dinosaurs). There's a couple others I'll post this weekend; they show a couple elements of triassic era synapsids and large mesozoic amphibians. One fills an ecological niche comparable to those of wolves; not that you'd be able to tell by looking at it. ; )
