Significance
''Pholidorhynchodon'' belongs to a group of fish that are right at the very base of the
teleosts. Teleost fish include almost all living fish species, and have their origins in the Triassic. This makes ''Pholidorhynchodon'' important because it provides information about the early evolution and development of this important group.
