Diversity of Mesozoic semionotiform fishes and the origin of gars (Lepisosteidae)
Naturwissenschaften, 2010Gars (Lepisosteidae) are ray-finned fishes with controversial relationships to other actinopterygian lineages. When fossil taxa are considered, gars are grouped with Mesozoic macrosemiids and 'semionotids' in the Semionotiformes, but the intra-relationships within this order are still elusive.

Family Lepisosteida (Gars) as Living Fossils
1984Gars (Fig. 1). are primitive neopterygian fishes with elongate snout, plicidentine teeth, opisthocoelous vertebrae, heavy dermal bone retaining ganoid ornamentation, ganoid scales, a semiheterocercal tail, and fulcral scales on the median fins. The elongate snout is an ontogenetic product of ethmoid elongation and is correlated with many of the ...

Copeia, 2014
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.

A propos du genre Paralepidosteus (Ginglymodi, Lepisosteidae) du Crétacé gondwanien
2001Les auteurs justifient le maintien du genre †Paralepidosteus pour l’espèce †P. africanus du Santonien du Damergou au Niger. Ils proposent de rapporter à ce genre, mais cependant avec quelque doute (?†Paralepidosteus sp.) et en justifiant leur position, des spécimens du Maastrichtien de Bolivie, du Brésil et d’Inde ainsi que l’espèce †P. praecursor de l’

The Southwestern Naturalist, 2004
Abstract The spotted gar, Lepisosteus oculatus, population in the Lake Pontchartrain estuary in southeastern Louisiana was sampled monthly to characterize its reproduction, age, and growth from November 1998 through October 1999. Males ranged from 285 to 568 mm standard length (SL) and 0 to 8 years; females ranged from 395 to 606 mm SL and 0 to 10 ...
