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...
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...
The Parahuman Baseline
While the first generation were bioprinted with titanium-reinforced bones, the complete lack of biological interaction exhibited by the metal made it impossible to code the trait into the genome.
Candy Forests
Candy Forests are an unique type of subtropical environment found over most of Mediterranean and Iberian Europe, Central and Western Australia, Western Madagascar and most of northern Mesoamerica, with "False Candy Forests" in South America, South...

Milk Egg
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. Marsupials eject joeys, monotremes eject eggs that...

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...
An Alternate History For Placodonts
Placodonts were some of the most resilient groups of Triassic marine reptiles, consistently surviving minor extinction events with minimal diversity loss until the mass extinction. In one timeline, this did not happen. Instead, their diversity...
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...
