Summary:A Middle Cambrian faunule from different sections of the San Isidro region, Precordillera of Mendoza Province, western Argentina, include previously unrecorded and new material. Specimens in the collections are simple reticulosan hexactinelliid determined as Diagoniella cf. cyathiformis, Diagoniella sp., (?) Diagoniella sp., indeterminate protospongioid spicule assemblages and several root tuft types. In addition a possible scleritome of Chancelloria cruceana Rusconi, 1954 is redescribed and figured and scleritos assigned to Allonia and Archiasterella are here described for the first time.
