Beyrichitine ammonoids of NV Nevada reveal a high taxonomic diversity of Anisian (Middle Triassic). This diversity is, however, in contrast to their relatively low morphologic disparity. Depending on the exact definition, morphologic disparity of a d

Ammonoids reached their greatest diversity during the Triassic period. In the early Middle Triassic (Anisian) stage, ammonoid diversity was dominated by representatives of the family Ceratitidae. High taxonomic diversity can, however, be decoupled fr

The Late Cretaceous echinoid genus Micraster (irregular echinoids, Spatangoida) is one of the most famous examples of a continuous evolutionary lineage in invertebrate palaeontology. The influence of the environment on the phenotype, however, was not

On the basis of the type material of a new species of micrasterid, Micraster woodi sp. nov., from the upper Turonian of Lower Saxony (Germany), intraspecific patterns in variability of 18 size- and shape-related indices were analysed. The results wer

A detailed re-description of the lectotype of “Spatangus cortestudinarium Goldfuss, 1829” [currently used as Micraster cortestudinarium (Goldfuss, 1829)], (designated by Stokes 1975), was undertaken and compared to previous taxonomic interpretati

Seven species of atelostomate (irregular) echinoids are described from Upper Cretaceous marl-limestone alternations in the vicinity of the village of Kalafatli (province of Zonguldak, Black Sea region, northern Turkey), namely Stenonaster tuberculatu

Based on representatives of the Late Cretaceous genus Gauthieria (Gauthieria radiata - Gauthieria spatulifera - Gauthieria princeps), ontogenetic trajectories within the family Phymosomatidae are described for the first time. Due to shared similariti

Spines of irregular echinoids occur in very high abundance in each specimen, and display distinct architecture as a result of the specialized functions of the spines; however, studies on spine microstructure in atelostomate echinoids have rarely been
