Fukuivenator
Fukuivenator paradoxus (Fukuivenator · フクイヴェナートル・パラドクサス)
Known only from fossils. The IUCN Red List assesses only species extant since 1500 CE, so fossil taxa are not assigned a category.

📖 1. Overview
Fukuivenator paradoxus (genus Fukuivenator) is a small theropod found in Early Cretaceous strata of Fukui Prefecture, Japan, and its name means "hunter of Fukui." The species name paradoxus refers to its unexpected mix of features from several dinosaur groups.
🦴 2. Anatomy & Morphology
It had 11 or more neck vertebrae—more than other theropods—and its teeth were varied in shape and lacked serrations. Its front teeth were small and spatulate, while the anterior upper jaw teeth were long and curved backward. Its forelimbs were about 75% as long as its hindlimbs, and it is estimated to have had about 35 tail vertebrae.
🔍 3. Fossil Record & Paleoecology
Although there is no direct evidence such as stomach contents, the paper considers it to have been at least omnivorous. The holotype specimen (FPDM-V8461) is housed at the Fukui Prefectural Dinosaur Museum.
🇰🇷 4. Connection to Korea
No direct record connecting this species to Korea has been found.
