Glyptorthis insculpta

Rhynchonellata - Orthida - Glyptorthidae

Orthis insculpta was named by Hall (1847). Its type specimen is AMNH 30260, a shell, and it is a 3D body fossil. It is the type species of Glyptorthis.

It was recombined as Hebertella insculpta by Hall and Clarke (1882); it was recombined as Hebertella (Glyptorthis) insculpta by Ladd (1929); it was recombined as Glyptorthis insculpta by Foerste (1914), Foerste (1924), Howe (1966), Li and Copper (2006), Zuykov and Butts (2008), Rubel (2011), Wright and Stigall (2014) and Liljeroth et al. (2017).

If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

D. F. Wright and A. L. Stigall 2014Large (character 1, width 20.24–25.69 mm) species of Glyptorthis with a subquadrate outline and fine concentric ornamentation weakly to strongly lamellose. Costal density low to moderate (see Online Supplementary Material Tables 2 and 4, character 11); ventral muscle scars large with lateral and anterior deflections; narrowing near the teeth. Ventral diductor scars separated by a medial septum; adductor scars of variable width, widening towards the anterior. Dorsal cardinal area high (character 31, Online Supplementary Material Table 2), extending over the hinge line; umbonal angle less than 150˚.
