The Holostei group occupies a critical phylogenetic position as the sister group of the Teleostei. However, little is known about holostean pituitary anatomy or brain distribution of important reproductive neuropeptides, such as the gonadotropin-inhibitory hormone (GnIH).

The lower jaw of Lepisosteus osseus has been described as containing a U-shaped cartilaginous structure identified as a detached portion of Meckel's cartilage. We investigated this structure through study of a growth series of L. osseus, including cleared-and-stained specimens and histological preparations.

Historical Biology, 2019
Ginglymodian fishes formed one of the most dominant actinopterygian lineages during the Mesozoic, occurring in fully marine to freshwater depositional environments. However, although commonly preserved in Mesozoic strata around the world, there is little information on the feeding ecology of these fishes, which is mainly due to the scarcity of direct ...

Abstract Here we report the first †obaichthyid gar from the Lower Cretaceous (Aptian) Codo Formation of the Parnaiba Basin, Northeastern Brazil. It shows the following obaichthyid characters: numerous odontods firmly attached to the outer surface of the dermal bones, free and mobile maxilla, presence of interopercle, lack of contact between the ...

Journal of Vertebrate Paleontology, 2016
A new ginglymodian fish, Khoratichthys gibbus, gen. et sp. nov., is described based on the impression of a single articulated fish preserved on a sandstone slab from the Late Jurassic–Early Cretaceous Phu Kradung Formation, northeastern Thailand. Khoratichthys gibbus is characterized by a distinct humpbacked body with elongate posterior spines on the ...

Copeia, 2015
This is the first in a planned series of studies in which we examine the cranial muscle ontogeny of exemplar taxa of actinopterygian clades to obtain a better understanding of the evolution of the cranial musculoskeletal system within the Actinopterygii. The Longnose Gar, Lepisosteus osseus, is a member of the basal actinopterygian family Lepisosteidae.
