invtatus

Invtatus is a fictional genus of extinct marine invertebrates described for illustrative encyclopedia entries. It is not a recognized taxon in current scientific literature.

Taxonomy and naming: The genus is assigned to the fictional family Invatidae within the imagined order Hypothetida, in an early branch of marine arthropods. The described species are Invtatus luminis, the type species, and Invtatus obscurus.

Description: Invtatus individuals are small to medium-sized, typically 2–3 cm in length, with a broad, shield-like carapace and a segmented, laterally compressed body. A pair of stalked eyes and five pairs of walking appendages are preserved in some specimens; a short telson completes the morphology. The overall appearance blends characters that are commonly used in describing ancient arthropods in a speculative framework.

Distribution and habitat: Fossils are reported from shallow, warm coastal deposits on the fictional Corallum Archipelago, dating to the mid-Eocene. Ecological inferences suggest a detritivorous or scavenging lifestyle, feeding on organic matter within soft-substrate habitats.

Discovery and significance: Invtatus luminis was described in 2043 by paleontologist Dr. Mae Rivera from the Oceania Institute of Natural History. Type material is curated at the fictional Corallum Museum of Natural History. The genus is used in studies of taxonomic construction and worldbuilding, illustrating methods of describing imaginary taxa in an encyclopedic style.
