Fossil genus of fishes
Oniichthys is an extinct genus of gar in the family Lepisosteidae . It contains a single species , O. falipoui , known from the Late Cretaceous (Cenomanian ) of Morocco .[ 1]
It is known from a few very well-preserved, near-complete specimens from the Kem Kem Formation , where it coexisted with the famous Spinosaurus .[ 2] It closely resembles the modern genus Atractosteus , and is generally placed as its sister genus , a sister to Atractosteus and Lepisosteus , or even as a species within Atractosteus as per Grande (2010),[ 3] although this latter view has been disputed based on differences in skull morphology.[ 4] [ 5]
The genus name references the Ooni , divine Yoruba kings, while the specific epithet honors Christian Falipou, who loaned one of the type specimens .[ 1]
