Biology:Eaglesomia
Eaglesomia is an extinct genus of freshwater catfish, most likely of the family Claroteidae, that inhabited western Africa during the Eocene.[1] It contains a single species, E. eaglesomei, known from the presumably Lutetian-aged marine Oshosun and Ameki Formations of Nigeria.[2]
Initially placed in the modern genus Chrysichthys, a 1934 reanalysis found it to be more similar to the Egyptian fossil catfish Socnopaea, and it was thus reclassified into its own genus within the Claroteidae.[3] However, a 2010 study found it to lack several characteristics of the Claroteidae, and thus not be a claroteid.[4] In contrast, a 2021 study retained it in the Claroteidae based on its distinctive skull ornamentation, which more closely resembled that of claroteids than any other catfish family.[3]
