The Last Placental
55 million years ago, Wyoming. A small mammal scurries along the tree branches. It is dusk, and it has just left its shelter in the deeper canopy to forage for food. It is an omnivore: it can do a little bit of everything, which is likely how it...
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
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 reccord as they are, with...
Spectember: Ichthyornithid Parrots
In one timeline crown birds didn't make it past the KT event, but ichthyornithids did. Like our birds they quickly radiated into a massive array of species; most of the initial niches were raptorial and insectivorous, but gradually aquatic plant eaters...
