Current identification/main database link: Buryella clinata Foreman 1973
(Based on 15 specimens) Length overall 140-195µm, length of cephalis and thorax 40-45µm, of third segment 50-75µm; greatest width 65-85µm.
PHYLOGENY Distinguishing characters (rw): The species described and illustrated here agrees will with the brief descriptions and illustrations of Nigrini [528:pl.2, fig.M] and of Riedel and Sanfilippo [2406:533]. It differs only in its greater size. This species is related to and distinguished from B. tetradica as described under that species. It differs from Theocorys trisulca Kozlova [1518:111, pl.17, fig.9] in the nature of the third (second?) segment which is described as having a tuberculate surface and round, scalloped, double contoured pores, unequal in size and irregularly spaced.[845:433]
The short, well developed apical horn has pronounced blades sufficiently wide to enclose the cephalis, and extending to the collar stricture. The third segment is the largest, with pores characteristically aligned transversely and diagonally. [2550:668]
Distinguished from its ancestor, Pterocodon ? anteclinata, by having a bladed rather than a conical apical horn.
Although the pores of the third segment typically are strictly aligned transversely and diagonally, very rare specimens have the pores of that segment irregularly arranged. The development of the fourth segment, and the degree of concavity of its outline, vary greatly. [2550:668] Phylogeny (rw): The limit between B. clinata and its ancestor Pterocodon (?) anteclinata Foreman [847:621] is drawn where the base of the horn becomes as wide as the cephalis. Co-occurring forms with which Buryella clinata might be confused are B. tetradica, in which the abdominal pores are aligned both longitudinally and transversely, commonly with longitudinal ridges separating the rows; and an undescribed form with less prominent horn, conical thorax with rough surface, distinct lumbar stricture, and thick-walled, inflated abdomen with regularly arranged pores.
