Prefrontal with a spiny anterior tip. Vomer bearing small rounded molariform teeth irregularly ranged. Frontal short, narrow and with a weakly developed median protuberance. Dermosupraoccipital, parietal and dermopterotic longer than deep and articulated with a large supratemporal. Long nuchal horn with a broad basis, a very spiny posterior border and resting on the dermosupraoccipital, the supratemporal and the posttemporal. Orbitosphenoid articulated with the mesethmoid. Well developed triangular dermosphenotic. Premaxilla long, broad, toothless and sutured by its dorsal margin to the prefrontal. Large, toothless and triangular shaped maxilla. Small lower jaw. Hypertrophied trapezoid preopercle covering a great part of the cheek. Small opercle with a rounded dorsal border and an acuminate ventral tip. Exposed part of the hyomandibula-dermohyomandibula considerably smaller than the preopercle. Very large pectoral girdle closely associated to the skull and forming a sort of cephalothorax. Posttemporal articulated with the supratemporal. Hypertrophied hypercleithrum. Strongly hypertrophied cleithrum with a long and broad ventral branch and a large posterior ventral process. Long pectoral spine articulated on the cleithrum. 17 neural spines, all fused to their neural arches, before the epichordal series. Neural and haemal spines short and broad. Postcoelomic bone obliquely oriented. Short dorsal fin located in the middle of the back, with 13 pterygiophores, 1 small spiny ray and 12 segmented rays. Very short anal fin. Caudal fin with a convex posterior margin and with 17 principal rays, 6 dorsal and 7 ventral procurrent rays. Body entirely covered with very small flake-like scales. No dorsal ridge scutes. One large postcloacal scute below the postcoelomic bone.</paragraph>

The snout is elongated in a short rostrum formed by the long and broad prefrontal and by the long toothless premaxilla. The anterior tip of the prefrontal is spiny. The rostrum outpaces only slightly the lower jaw level. The anterior region of the long mesethmoid and the vomer are hidden by the prefrontal and the premaxilla. However, the most anterior part of the premaxilla is broken on face CLC S-413b and a part of the vomer is visible. The bone bears very small, rounded molariform teeth, irregularly ranged.</paragraph>

It extends anteriorly beyond the orbit level and exhibits a weakly developed median protuberance located just before the orbit, but there is no frontal horn. The posterior region of the skull roof is formed by the dermosupraoccipital, and the paired parietals and dermopterotics. These bones are rather small and longer than deep. There is no temporal fenestra. A large supratemporal is sutured with the posterior margin of the dermosupraoccipital, the parietal and the dermopterotic. The autosphenotic is located below the dermopterotic. A long and strong pointed nuchal horn with a series of large spines on its posterior border is resting on the dermosupraoccipital, the supratemporal and also the posttemporal. The very broad basis of that horn extends on the beginning of the back.</paragraph>

The lower jaw is triangular in shape and rather small. The dentary is reduced to its ventral branch. Its ventral margin is spiny. The teeth are not preserved. Other gladiopycnodontid genera have two teeth on the dentary. There is a large angular and a small articular. It is not possible to determine whether the prearticular was toothed or not or whether a marked coronoid process was present. The prearticular bears molariform teeth on its inner face in some other gladiopycnodontid fishes.</paragraph>

The pectoral bones are ornamented with small tubercles. The posttemporal is a deep bone, narrow in its upper part but ventrally broader, that is sutured anteriorly to the supratemporal and dorsally to the nuchal horn. The hypercleithrum (= supracleithrum) is hypertrophied in a large, more or less ovoid plate. The cleithrum is gigantic, with a well developed dorsal branch, a long and broad ventral branch and a very large posterior ventral process. The pectoral fin is replaced by a long strong spine. There is no soft ray.</paragraph>

The abdominal part of the axial skeleton progressively elevates and anteriorly reaches the orbit level. The vertebrae are constituted by the dorsal and ventral arcocentra only. The notochord is not completely surrounded by the arches. There are 17 neural spines before the epichordal series of the caudal skeleton. They are short, but rather broad. All those neural spines are fused to their neural arches. Non of them are autogenous. The first neural spine corresponds to the first ossified neural arch. The fourth neural spine is fused to two neural arches. That is probably an individual variation and not a specific character. A few badly preserved traces of the basiventrals from the abdominal region are visible, but the basiventrals of the caudal region and the haemal spines are lost, except the last ones near the tail. Four long and strong ribs are seen just behind the hypercleithrum on face CLC S-413b. The few preserved haemal spines are short and broad, as the neural spines.</paragraph>

A caudal peduncle is present. The caudal skeleton is not very well preserved, but the two faces CLC S-413a and b complete each other and allow to entirely reconstruct the whole structure. The caudal fin is dorsally supported by 5 epichordals and ventrally by 12 hypochordals. The tenth and eleventh hypochordals are moderately broadened, but there is no real hypertrophy. The hypochordal series begins one vertebral segment before the epichordal series. No urodermal is visible, but this is probably a taphonomic artefact. Indeed, a well developed urodermal does exist in some gladiopycnodontid fishes more specialized than
