Unfortunately, identifying the specific taxa that produced them is not possible, but their association with various fossils from acanthodian, actinopterygian, sarcopterygian, and rhipidistian (crossopterygian) fish suggests that any of these are potential sources of the coprolites and nonspiraled cololites.
Schultze also supported Gross's position that Andreolepis is the most primitive actinopterygian and considered (Schultze 1996, p.

Genomic information is now available for the actinopterygian holostean spotted gar, which has 13 paralogs (copies of Aqp0, -1, -3, -4, -8, -9, -12, -14, and -15, with two copies each of Aqp 10 and 11; Finn et al.

As stressed by authors such as Hilton & Bemis (1999), there are documented cases, within actinopterygian fishes, of remarkable morphological variation within a single genus, a single species, and even within a single population of the same species.
The functional design represented by basal loricarioids is therefore relatively unmodified from the basic biomechanical design shared with outgroup actinopterygian (ray-finned fish) taxa (Lauder 1985).
Although Mauthner cells have been identified in a large number of taxa broadly representing the phylogenetic diversity of actinopterygian fishes, a few species appear to lack these neurons [8].
