Cribrilinidae Hincks, 1879

Colony encrusting or erect. Frontal wall with extensive area of frontal membrane, almost entirely concealed by a shield of calcified hollow flattened spines, merging as a costal area, with openings between the spines for the passage of water from the epistegal space beneath the shield. Pseudopores may be present on the costal spines. Gymnocyst extensive to absent. The primary orifice is uncalcified; the opening in the frontal shield is a secondary calcified orifice, its appearance variable, depending on the development of the distal pair of costal spines. Oral spines present in some forms. Avicularia adventitious, or interzooidal to vicarious, or absent. Ovicells hyperstomial, prominent; with smooth calcification or with varying types of windows in the ectooecium, or with pseudopores.

The great variety of Cretaceous cribrimorphs have been subdivided, by Lang (1916, 1922), into at least 11 other families, with several subfamilies. Until a modern revision is attempted, these are all included here into the family Cribrilinidae. These families are:

Andrioporidae
Calpidoporidae
Ctenoporidae
Disheloporidae
Lagynoporidae
Myagroporidae
Otoporidae
Pelmatoporidae
Rhacheoporidae
Taractoporidae
Thoracoporidae
