DIAGNOSIS. — “Test consists of a single round-triangular cortical shell, without medullary shell and internal spicule. The shell is composed of two spongy layers.

Numerous beams connect the two layers.” (Feng in Feng et al. 2004: 137).

International audience; The purpose of this paper is to present a revised classification of Paleozoic radiolarians at the genus level in the form of a series of plates displaying the images of the type species of each genus. These photos are supplemented by an indication of the status of the genus decided by an international teamof specialists in this fossil group (Chapter “The catalogue”). The catalogue itself is presented by orders and families. It is also possible to find a genus using the alphabetical list or the list according to the classification (Appendices 1 and 2). After some remarks that illustrate the complex task undertaken to reach a consensus, a “guide for users” is proposed.; Le but du présent document est de présenter une classification révisée des radiolaires du Paléozoïque à l’échelle des genres, sous la forme d’une série de planches présentant les images des espèces types. Ces images sont complétées par l’indication du statut du genre décidé par une équipe internationalede spécialistes de ce groupe fossile (chapitre « The catalogue »). Le catalogue est organisé par ordres et par familles, mais il est également possible de trouver un genre en utilisant la liste alphabétique ou celle suivant la classification (Annexes 1 et 2). Après quelques remarques montrant le travail complexeeffectué pour aboutir à un consensus, un « guide pour les utilisateurs » est proposé.
