DESCRIPTION / ABSTRACT A desiccated bipedal specimen of unknown identity is on public display at the Nemo oceanarium in Anapa, Russia, labelled "Found at the bottom of the Black Sea — Unknown." This paper does not claim that authenticity is established. It argues that the specimen has traits of potential authenticity, and that those traits warrant formal physical examination. The case rests on four lines of evidence. First, the fossil record documents a bipedal trajectory within the crocodile line, from facultative Triassic forms to large, habitually bipedal Cretaceous trackmakers (Batrachopus grandis; Kim et al., 2020). An upright, plantigrade, tailless form with free forelimbs is the predicted endpoint of that trajectory, and it is the form the specimen presents. Second, the specimen was on display by September 2018, about two years before that peer-reviewed description, as documented by a server-dated public review. Third, apparent marine encrustation, including possible bay barnacles (Amphibalanus improvisus), makes its stated seabed recovery physically testable. Fourth, several features would carry internal biological structure if genuine: callus across an apparently healed rib, replacement teeth beneath the functional tooth row, claw bones inside discoloured claw tips, and the crocodile-normal ankle joint. Non-destructive CT can see these. The paper sets out a feature-by-feature comparison with crocodylian anatomy, the cultural memory of upright crocodilian forms in artifacts and mythology, a staged examination protocol with defined outcomes for each test, and an interpretive life reconstruction built from the evidence.
