Balcoracania dailyi is a small (typically about 1.5 centimetres (0.59 in))[1] trilobite of the family Emuellidae.
[2] The genus name is derived from Balcoracana Creek in the Flinders Ranges, one of the sites where fossils of Balcoracania were collected.
[1] It can be recognised by a short field between the front of the axis in the head (or glabella) and the border ridge, and a semi-circular headshield, as compared to touching glabella and border, and the sub-pentagonal head, in the sister-genus Emuella.
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.
[3] Balcoracania dailyi was an inhabitant of protected, shallow, marginal, marine environments.
