frontalids

Frontalids is a term that appears in a small subset of scholarly writings as a proposed designation for a group of organisms or features linked to the frontal region. There is no single, widely accepted definition, and the term has not achieved formal recognition in major taxonomic or anatomical references.

In paleontological and anatomical discussions, frontalids has been used to describe a hypothetical clade or morphological category defined by distinctive frontal-region traits, such as patterns of cranial ornamentation or developmental features of the frontal bone. Because these uses are speculative and not standardized, the term is often treated as provisional and may lack clear diagnostic criteria or a confirmed phylogenetic basis.

Etymology derives from Latin frons "forehead, front," with the suffix -id indicating likeness or membership. The plural frontalids is used when referring to multiple instances of the proposed category.

As a caution, frontalids remains a fringe or provisional term rather than a settled concept; readers should consult the original sources for how the term is defined in a given context, as definitions can vary.
