摘要

本文报道了Sergipe-Alagoas盆地Albian时代Riachuelo组棘皮动物Phyllobrissus humilis（Gauthier，1875）的新发现。在Maruim 1露头中获得的唯一标本表达了主要物种特征。提出了古生态学注释和二分法关键字，以便于识别Sergipe-Alagoas盆地白垩纪的决明子类物种。

A new Cassiduloid (Echinodermata, Echinoidea) in the Albian of the Sergipe-Alagoas basin, Brazil

This paper presents a new discovery of the echinoid species Phyllobrissus humilis (Gauthier, 1875) from the Albian age Riachuelo Formation of the Sergipe-Alagoas Basin. The only specimen obtained in the Maruim 1 outcrop expresses the main species characteristics. Paleoecological notes and a dichotomous key are presented to facilitate the identification of the cassiduloid species from the Cretaceous of Sergipe-Alagoas Basin.
