Etude comparative de quelques Ischyrosponges

Abstract

The study of several collections gathered in mediterranean countries, North Africa, Greece, Italy, Yougoslavia, South of France, and some other areas allows to precise the con¬ nection of a number of incertae sedis, supposed Algae or Stromatoporoids, to the Ischyrospongia (hypercalcified Sponges). The study concerns some palaeozoic forms either well known (. Amphipora , Stachyodes) ox less frequent (Aoujgaliida Termier, Termier et Vachard 1975), and mesozoic forms (Cladocoropsis, Sarmentofascis n. gen and Consobrinomia n. gen.). The relations of Idiostromidae with Permosphincta Sponges are considered. A sarmentoid texture common to several genera is defined for the first time. A number of taxa are created : Cladocoropsidae n. fam. , Consobrinomiidae n. fam., Sarmentofascis nov. gen., S. benesti n. gen. n. sp., S. chabrieri n. gen. n. sp. , Sinustacheoides n. gen. , Aoujgalia regularis n. sp. , Valuzieria n. gen. , V. sescenti n. gen. n. sp. , Chantonia n. gen. , Epistacheoides ( ?) richi n. sp. , Roquesselsia n. gen. , R. radians n. sp. , Consobrinomia n. gen. , C. elegans n.gen. n.sp. of France, and some other areas allows to precise the con¬ nection of a number of incertae sedis, supposed Algae or Stromatoporoids, to the Ischyrospongia (hypercalcified Sponges).

Late Viséan-early Serpukhovian cyanobacteria and algae from the Montagne Noire (France); taxonomy and biostratigraphy

“…• L -Valuzieria sescenti Termier et al, 1977 emend. herein, thin section MA-RM1, Roc de Murviel, latest Viséan.…”

“…Nevertheless, as the true E. elongata more resemble species of Donezella, we assign herein the misinterpreted taxon of Bogush et al (1990) Remarks. -Created as a distinct genus by Termier et al (1977), Valuzieria was synonymized with Aoujgalia by Vachard & Cózar (2010). However, our new material proved that Valuzieria is transitional between Aoujgalia and Asteroaougalia, and not really synonymous of one or each other of both genera.…”

“…• S -Roquesselsia radians Termier et al, 1977, thin section MA-10-7, Castelsec, early Serpukhovian. However, this latter species, which is a true Issinella as recently redescribed by Okuyucu et al (2013) (i.e., a tube with any irregularities, and randomly arranged laterals), entirely differs from Luteotubulus (the exact spelling of this taxon) and Zidella (see remarks in Vachard 1993).…”

“…), and 'Windsoporella'; Figure 7), as well as the problematic dasyclad Chlorophyta Koninckopora (Figure 7). Diagnosis of the previous genera can be found in the works of Mamet and Roux (1975a, 1975b, Perret and Vachard (1977), Termier et al (1977), Vachard and Montenat (1981), Mamet (1991), Vachard and Beckary (1991), Cózar and Vachard (2003), and Vachard and Cózar (in press). Only the Rhodophyta and Chlorophyta are algal groups with clear modern equivalents, whereas the rest of the taxa can be considered as problematic algae or incertae sedis.…”
