... Twelve species of fossil echinoid have been recognized from the Jamaican Cretaceous. Only two taxa, the cidaroid Phyllacanthus leoni (Lambert and Sánchez Roig) and the arbacioid Goniopygus supremus Hawkins, are known from the Cretaceous of both Jamaica and Cuba. They are also the two most...

... a locus for colonization by rocky substrate-preferring organisms such as terebratulid brachiopods, cidaroid echinoids and articulate crinoids. The Liard reef mounds accumulated during periods of comparably low siliciclastic input to the shoreface, likely during the later stages of a highstand systems...

... The Jamaican Cenozoic echinoid fauna is large and diverse, comprising about 95 nominal species (with further taxa presently classified under open nomenclature) divided between 43 genera. The Eocene fauna is particularly large and includes about 85% of the Jamaican Cenozoic species. In contrast...

Kier Abstract Triassic echinoids are rare, particularly in North America where only two species have been described [from California], both of which are based on [cidaroid] fragments which cannot be generically identified. These fragments are herein reillustrated and redescribed. More...

... °C at Shangsi. A species of cidaroid echinoid likely migrated to cooler deep waters to optimize development, suggesting that the success of this shallow-water clade is attributable to such refugia, when survival was most precarious after the EPME. The ecosystem was short lived, depending on low...

... of stem group taxa from the Permian as well. Crenulate tubercles are reported from two taxa, and putative cidaroid style U-shaped teeth are present in the fauna. The presence of crenulate tubercles in the archaeocidarid indicates that crenulate tubercles were present in stem group echinoids, and thus...
