Polydenttejas

Polydenttejas is a fictional genus created for speculative biology and world-building. The name combines elements suggesting many teeth with a phonetic ending chosen for aesthetic purposes. It is presented in imagined scientific contexts as part of a coastal-marine fauna from a Cretaceous-like era on the fictional continent of Marelia.

Description and morphology: Polydenttejas is described as a carnivorous archosauromorph with a long, narrow snout and a dentition arranged in multiple series. The upper jaw is said to host up to three functional tooth rows, while the lower jaw has two, a configuration described as poly-dentate. The skeleton is depicted with robust forelimbs and a strong pectoral girdle, and a tail adapted for maneuvering in shallow, coastal waters.

Habitat and ecology: In the fictional world, Polydenttejas inhabits nearshore and estuarine environments, feeding on fish, cephalopods, and other small marine organisms. Its dentition is presented as an adaptation for gripping slippery prey, with a hypothesized feeding strategy that combines grasping with short bursts of rapid jaw closure.

Discovery and taxonomic status: The genus was first proposed in a speculative field guide published in 2089 by paleontologist L. Kestrel. No fossil material exists outside the fictional setting, and Polydenttejas is not recognized by real-world scientific authorities. In-universe sources use Polydenttejas to illustrate concepts in convergent evolution and functional morphology.

Significance: Polydenttejas serves as a rogues’ gallery example in world-building of how dentition can evolve in diverse lineages to exploit similar ecological niches. See also speculative evolution and fictitious taxa. References are limited to in-universe publications.
