Spumellaria gen. et sp. indet.

( Fig. 5L )

FIGURED SPECIMEN. — ULVG-7341.

MATERIAL. — Four specimens (recovered with the hydrogen peroxide method); two specimens (recovered with the acetic acid method).

DESCRIPTION

Test ellipsoidal, possibly composed of a spongy meshwork and without radial spines. Pores are of sub-circular outline and the skeleton surface is smooth.

REMARKS

The absence of diagnostic features does not enable a precise identification.
