Abstract:
Irregular echinoids (Order Spatangoida) from the Cretaceous of Mexico. Echinoids are a very important part of the Mesozoic and Cenozoic fossil fauna of Mexico. Among them, spatangoids are widely represented in several Cretaceous fossiliferous outcrops, and have stratigraphical and paleoecological value due to their good preservation of the Cretaceous. The review of order Spatangoida L. Agassiz, 1840 from the Cretaceous in Mexico allowed un update the taxonomy of species and contributed to the study of paleogeographic and stratigraphic distribution. The order Spatangoida is the most diverse in

Abstract:
Abstract Members of the echinoid order Spatangoida, a highly diverse and abundant marine invertebrate clade, were important denizens of the Cretaceous Western Interior Seaway (WIS), an epicontinental seaway that divided North America in two during an interval of greenhouse conditions between roughly 100 and 65 million years ago. A phylogenetic analysis of spatangoids was conducted using a character matrix of 32 characters from 21 species. Species that occur in the WIS were considered comprehensively, and species from other regions such as South America, Europe, and North Africa were also incor
