Another World's Lijialaowu
In a world where the KT event didn't happen, all bets truly are off. Even in the placid climate of the Paleocene - just before the Eocene Thermal Maximum and its ensuing turnover, long before the drastic changes of the Cenozoic - entire biotas were...
Electromagnetic Flyers
In the Late Cretaceous a lineage of deltatheroidean metatherians developed specialised, tightly packed hairs with branching filaments, superficially similar to plumes. This permitted an unique development in vertebrate history: by extending these hairs...
Speculative Evolution: Herbivorous Eutriconodont
In some other timeline, a lineage of eutriconodonts (specifically, within Triconodontidae) survive the KT event in Asia. Though succeeding as carnivores in the absence of carnivorans, one genus, Cynoailurus, begins specializing as bamboo specialists....

Seahorse Placoderms
A speculative evolution exercise in an alternate timeline two lineages of placoderms convergent with syngnathid fish evolved: - longmaiformes were a clade of arthrodires of uncertain affinities as they more or less appear in the mid-devonian fossil

Milk Egg
Another speculative evolution musing non-placental mammals are faced with an unique predicament. possessing epipubic bones, they cannot expand their torsos, and thus cannot give birth to complex, well developed young you take for granted.
HATSSSSS Chapter Twenty-nine
It wasn’t the proper time to think about speculative evolution. it was snack time. he was about to pocket his phone when he received a call. leo looked at the screen. wait, that was him.
