Echinocardium fenauxi Pequignat 1963
Family: Echinocardiidae	Order: Spatangoida-Micrasterina
Locality: Croatia, Losinj	Dimensions: 53 x 50 x 30 mm
I erroniously regarded this specimen for a longer time as Echinocardium cordatum. But as in the frontal ambulacrum two rows of regularly arranged single pores are present it is rather Echinocardium fenauxi. Echinocardium cordatum has also two series of pores, but irregularly arranged and more crowded.
