Emuella is a genus of Cambrian trilobites of the family Emuellidae.
Dalgarno, who discovered Balcoracania dailyi in the Flinders Ranges, near Blinman, South Australia.
[2] It can be recognised by touching glabella and frontal border, and the sub-pentagonal head, as compared to, a short field between the front of the axis in the head or glabella and the border ridge, and a semi-circular headsheald in the sister-genus Balcoracania.
Both emuellid genera share eye ridges that are positioned parallel to the frontal and lateral border of the head, prominent genal spines that are a smooth continuation of the lateral margin of the head, a prothorax of 6 segments, with the 5th and 6th merged and carrying large trailing spines.
Both genera have in adulthood a highly variable but large number of segments of the opistothorax, although the largest number found in B. dailyi with 97 is much larger than in Emuella (52).
