Whitephippus: a 3D Eocene moonfish
Davesene et al 2024a, b reported on
a new 3D set of fish skulls assigned to Whitephippus tamensis from the London Clay Formation, early Eocene (50mya, Figs 1, 2).
Davesne et al wrote,
“Whitephippus, known by several specimens has been attributed to the extant family Ephippidae (spadefishes) by Woodward (1901) and Casier (1966). However, some authors (Bonde, 1995; Carnevale, 2004; Friedman et al., 2016) have proposed that †Whitephippus should be classified with Lampriformes instead.”
The Lampriformes is a traditional bony clade
(Fig 3) consisting of Lampris and Regalecus (opahs and oarfish, Fig 2) and other dissimilar taxa. That clade is not recovered by the LRT where Lampris nests with flying flish and Regalecus nests with Mene the moonfish (Fig 2), a taxon not mentioned in the text. Mene compares well in size and morphology with Whitephippus.
Add taxa
to test this hypothesis of interrelationships for yourself.
