Abstract
Echinoids offer a unique opportunity to investigate the evolution. Our efforts of exploring extensively the fauna of Zirabad (Lat. 22024’30” : Long. 75004’30”) has yielded some of the new irregular Echinoid fossils not cited before from this area. The present paper documents detailed morphology of one such well preserved sample of Nucleopygus sp from the nodular lime stone formation exposed at Zirabad near Manawar, Dhar district of Madhya Pradesh, India. The investigation enhances our knowledge on irregular Echinoids from bagh group.
