Ajaperioodis
Ajaperioodis is a fictional taxon used in world-building and speculative biology to illustrate patterns of amphibian evolution. In the imagined biota of a hypothetical continent, ajaperioodis refers to a small to medium-sized semi-aquatic amphibian that lived during the Late Cretaceous.
Taxonomy and morphology: In the constructed framework, Ajaperioodis is placed in a notional family Ajaperiidae within
Habitat and ecology: Fossil-like deposits for this fictional taxon are attributed to river-delta and floodplain environments
Discovery and naming: The genus is described in a hypothetical 21st-century field guide by a fictional paleontologist,
Significance: The ajaperioodis construct is used to explore concepts of convergent morphology, paleogeography, and functional anatomy
