Each exoccipital articulates with the caudolateral edge of the supraoccipital and laterally with the caudomedial edge of the opisthotic, as well as ventrally and medially with the basioccipital (Figure 1D).
However, most gonorynchiforms examined by us exhibit a well-developed, paired ossification that is usually named 'cephalic rib' but that is strikingly similar to the ossified Baudelot's ligament of teleosts such as catfishes, connecting the cleithrum and/or supracleithrum to the posteromesial surface of the neurocranium (usually exoccipital and/or basioccipital) (e.

El exoccipital se ubica posterior, del cual salen los condilos occipitales, uno a cada lado para articular el craneo con la primera vertebra.

The second corresponds to the cranioquadrate passage and begins at the otic aperture and runs posteromedially, with the exoccipital forming its dorsomedial margin.
Son animales pequenos, de color gris plomizo en el dorso y ligeramente mas palidas en el vientre, con una cola relativamente corta, se distingue porque presenta un borde craneal postorbital prominente, generado por la extension de la fosa glenoidea, con un pequeno proceso paraoccipital que sobresale del exoccipital y un proceso coronoide estrecho en relacion con la altura.

La parte ventral del supraoccipital se une al arco exoccipital por una banda de cartilago, tambien en el extremo superior del complejo neural y entre el margen ventral del complejo neural y la superficie dorsal de la tercera vertebra.
In the cases of atkinsi, auriculatoides, coqui, dimidiatus, jugans, pinarensis, ricordii, teretistes, and ventrilineatus, he could see a suture between the frontoparietal and exoccipital in each of these taxa and concluded that there was no frontoparietal-prootic fusion.
