One complexity distinct pattern is that of the taxon Osteichthyes, whose diversity in the Early Permian is at a minimum, only increasing sharply from the beginning of the Triassic.
Identificamos especimenes atribuibles a taxones pequenos: Dasypodidae (0,9%), Ranidae (0,4%), Rodentia (2,8%), Aves (9%) y Osteichthyes (16,7%).
Aumentan significativamente los especimenes relacionados con Osteichthyes (39,4%); baja el porcentaje de Aves (5,4%) y continua siendo importante la categoria, menos inclusiva, 'pequenos' (P) (29,3%); el resto se distribuye entre Dasypodidae y Ranidae, Rodentia confirmando el predominio de taxones pertenecientes a fauna de tamano pequeno.
El 56,8% corresponde a Osteichthyes, disminuyendo el porcentaje de los especimenes oseos identificados como 'pequenos' (P) (19,8%).
En cuanto a la identificacion, los porcentajes mas altos se distribuyen entre las aves (5,9%), Osteichthyes (22,1%), mamiferos pequenos (23,5%) y pequenos (21,3%); los no identificados alcanzan el (22,8%).

For trophic group B, larval juvenile Osteichthyes and adult euphausiids together accounted for over 80% of the total percent similarity in diets among the three nekton, and larval-juvenile Osteichthyes accounted for 60% of the overlap.
Most of the similarity in diet within this trophic group was due to larval-juvenile Osteichthyes (70% of total similarity).
For adult coho salmon, adult and larval-juvenile Osteichthyes contributed >95% of the diet in 2000, and brachyuran larvae contributed approximately 50% of the diet in 2002 (Fig.
Diet analysis of 26 nekton species of the northern California Current ecosystem revealed general trophic groups that primarily consumed adult Osteichthyes, larval-juvenile Osteichthyes, euphausiids, mixed zooplankton, and copepods; however, in each trophic group omnivory was expressed and actually predominated in some nekton trophic groups.
