Spongillida View in CoL gen. et sp. indet. sensu Schindler et al. 2008
Fig. 10 View Fig .
Horizon: Stefanian–Autunian, Permo-Carboniferous.
Locality: Donnersberg, Friedelhausen, Lemberg, Saar-Nahe Basin, Germany.
References: Schindler et al. 2008.
Description (emended from Schindler et al. 2008).—Megascleres. In Lemberg, oxeas (379–1250 μm in length) smooth, slightly curved, sharp at both tips and with traces of the central axial canal. The oxeas length/diameter ratio is between 8.4 and 12.5. In Donnersberg, oxeas (300–900 μm in length) smooth, some slightly curved. Traces of a threadlike and thin central axial canal only occasionally visible. The length/diameter ratio is between 10.4 and 26.7. In Friedelhausen, the only proven megasclere is a translucent smooth oxea just under 1 mm in length. Microscleres, gemmuloscleres and gemmules not detected.
Remarks. —The material is reported simply as freshwater siliceous sponges from three localities. The spicules from Donnersberg and Lemberg seem to be identical. In comparison to extant Spongillida species the dimensional range of spicules is unusually wide, indicating the possibility that more than a single species might have been involved. There are no doubts about sponge nature of the spicules, and its freshwater occurrence is based on geological context.
Spongillidae spp. sensu de Laubenfels 1955
Horizon: Jurassic.
Locality: Unknown.
References: De Laubenfels 1955, Schindler et al. 2008.
Description. —No description and figures available.
Remarks. —The material is reported simply as freshwater siliceous sponges. Schindler et al. (2008: 1) in their introductive chapter, refer that “the oldest freshwater siliceous sponges are known from Mesozoic deposits (Jurassic, no details of location and taxon)”, indicating de Laubenfels 1955) as reference. This latter paper ( de Laubenfels 1955: E34) refers to freshwater sponges indicating that 3 genera of fossil freshwater sponges are known from the Jurassic to Recent. More details are supplied at page E37: “ Spongilla Jurassic to Recent); Meyenia (Pleistocene to Recent), and
Heteromeyenia (Pleistocene to Recent)”. Jurassic occurrence refers most probably to Hinde (1883).
