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...

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...

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...

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...

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...
