? Family CONOCARYOMMIDAE Lipman, 1969

Conocaryomminae Lipman, 1969: 481.

Conocaryommidae – Empson-Morin 1981: 260. — Amon 2000: 29. — De Wever et al. 2001: 126-127 ( sensu emend. ). — Afanasieva et al. 2005: S277-278. — Afanasieva & Amon 2006: 116.

TYPE GENUS. — Conocaryomma Lipman, 1969: 184 [type species by original designation: Conocaryomma aralensis Lipman, 1969: 186].

INCLUDED GENUS. — Conocaryomma Lipman, 1969:184 (=? Conocromyomma n. syn.).

DIAGNOSIS. — Conocaryommidae are characterized by a spherical cortical latticed shell with many tubercles and a central spherical part. The central part consists of three to five tight spherical concentric shells. A large space is present between the cortical shell and the innermost spherical part.

STRATIGRAPHIC OCCURRENCE. — Early Eocene-Late Eocene.

REMARKS

According to one of us (PD), Conocaryomma differs from Praeconocaryomma Pessagno 1976 due to the presence of a phorticiid-type-type central structure. However, no support photos have been published. Conocaryomma tuberculata ( Lipman, 1949) illustrated in text-fig. 7 of Lipman (1949) is different from Praeconocaryomma (Schmidt-Effing 1980: fig. 5). The latter possesses a central spherical part with a double medullary shell and a relatively larger third spherical shell. The exact same structure to Praeconocaryomma was drawn in the type series of the type species for Conocaryomma by Lipman (1969: pl. 1, fig. 4; pl. 2, fig. 1) but this drawing is imprecise according to the personal observation (PD).

VALIDITY OF GENERA

Conocaryomma

The internal structure is characteristics in Conocromyomma but is unable to be really evaluated due to the lack of illustrations of real specimens except the type specimen. We simply synonymize Conocromyomma with Conocaryomma in a future study.
