Two new echinoid genera and species, Salvaster roberti gen. et sp. nov. and Pygolampas edita gen. et sp. nov. are described. They were collected in the Calcaires à Spatangues Formation (CSF) that consists of limestone and clay sediments deposited in the southeast of the Paris Basin (France) during the Early Hauterivian (Early Cretaceous). The CSF is dated from the Acanthodiscus radiatus chronozone, a time-interval of overall high sea level in Western Europe, but it yields a rich shallow-water fossil fauna mostly represented by benthic invertebrates. Of the 54 echinoid species ever described in the CSF, 26 species are recognized here. They are distributed into 16 different families, among which regular (13 species) and irregular (13 species) echinoids are represented in equal proportion. This work confirms the high level of echinoid diversity in the CSF for that time-period.
