status

 

Genus Tectulipora Hall, 1888

TYPE SPECIES. — Fenestella (Tectulipora) loculata Hall, 1888 , by original designation. Lower Helderberg Group , Early Devonian (Lochkovian) ; New York, USA .

OCCURRENCE. — Lower to Upper Devonian of North America and Eurasia.

DIAGNOSIS. — Reticulate colonies, conical or fanshaped, planar or longitudinally pleated, frontal surface exterior if conical. Branches wide, moderately sinuous, closely or intermediately spaced, dichotomously divided. Two rows of autozooecia per branch. Straight to sinuous, high club-shaped median keel on obverse side of branch, composed of core of granular skeleton and sheath of laminar skeleton. Axial wall between autozooecial rows straight in tangential sections, continuing unbroken in superstructure; superstructure corresponding with underlying branches and dissepiments or with autozooecial apertures, consisting of laterally expanded laths borne on continuous skeletal sheets from branches and dissepiments. Autozooecia not strongly inflated laterally, commonly rectangular in deep tangential section; transverse walls at intermediate or high angle to reverse wall; hemisepta absent. Intermediate- to large-diameter short distal tube, opening frontally or slightly inclined laterally; apertural peristome present or absent; terminal diaphragms planar where present, with central boss in some species. Laminar extrazooecial skeleton traversed by small to moderate microstyles.

COMPARISON

Tectulipora Hall, 1888 differs from Loculipora Hall, 1885 in having less sinuous branches which are joined by dissepiments instead of anastomoses in Loculipora . Transverse connections in the superstructure of Tectulipora do not contact with dissepiments, whereas the superstructure in Loculipora is produced by extensions of both median keels and dissepiments.
