nomina dubia is a scientific name that is of unknown or doubtful application. In the case of pinnipeds (in particular phocid seals) a lot of fossils are fragmentary, yet given names to known or new taxa based on ecomorphotype groupings. Rule, Burin & Park (2024) find that such categorization is not reliably useful for assigning isolated fossils names and consider the majority of extinct phocid seal species to be nomina dubia.
