Summary: | This paper continues our revision of Yu.L. Pelman’s collection of the superfamily Acrotheloidea (phosphatic brachiopods) and of our own material from the Early–Middle Cambrian of the Siberian Platform. The following representatives of the superfamily Acrotheloidea (order Lingulida, class Linguliformea) are restudied and revised based on new techniques: the genus
Botsfordia
(family Botsfordiidae Schindewolf, 1955) and the genera
Acrothele
,
Eothele
, and
Orbithele
(family Acrothelidae), which are widespread on the Siberian Platform. Only one out of the three
Acrothele
species described by Pelman is recognized as a valid species, and one new species of this genus that comprises some part of the brachiopods that Pelman figured and placed in another taxon is described. All these species are described using data on shell microsculpture and microstructure. In addition, the genera
Eothele
and
Orbithele
are described for the first time from the Siberian Platform. |
