Type specimens. Poulsen (1927) unnumbered, cranidia; USNM 62707 About USNM , hypotype (Morgan, 2021), thoracics and pygidium .

Occurrence. Cape Wood Formation and Henson Gletscher Formation, Greenland; Stephen Formation, British Columbia; Carrara Formation, California and Nevada; Emigrant Formation, Split Mountain, Nevada; La Laja Formation, San Juan, Argentina; possibly Bright Angel Formation, Grand Canyon, Arizona; all Glossopleura Assemblage Biozone , Glossopleura walcotti Interval Biozone (Morgan, 2021) , (Wuliuan, Miaolingian).

Material examined. USNM 62707 (see Morgan, 2021); USNM 208256, USNM 208258; unnumbered specimens in Poulsen, 1927, pl. 16.

Remarks. Glossopleura walcotti is identified mainly by deep S1 glabellar and occipital furrows, although these can of course vary due to taphonomic factors quite independently from actual morphology. The presence of G. walcotti in the Cadiz Formation was proposed by Fuller (1980), but this could not be confirmed by the present study and most specimens are likely G. mohavensis .
