Remarks
The otoliths of A. fornicatus are characterized by a salient angle in the middle of both their dorsal and ventral rims. This provides them with a very recognizable overall lozenge shape (rhombus- or diamond-shaped). This feature is not seen in otoliths of any of the extant congrid genera, but a somewhat similar looking shape is seen in the Maastrichtian Alaconger triquetrus Schwarzhans, 2010 from the Gerhartsreiter Beds in Bavaria, Germany ( Schwarzhans 2010). This Maastrichtian species, however, has a higher dorsal expansion and does not show the very salient anterior and posterior ends seen in A. fornicatus .
