Homo georgicus would be assigned to Homo erectus using the Fossilized.org alpha taxonomy
Original diagnosis:"mandible D2600, almost complete, right and left P2 and the left M1 are absent. D2600 differs from the complex H. habilis, rudolfensis, ergaster and erectus by its large dimensions, particularly: length and height, the breadth of the body of mandible (at M3 = 92.4 mm) which is superior to those of habilis and ergaster and is close to the lower values obtained for Asian H. erectus; the length of the alveolar arcade, which is superior to those of habilis and ergaster and all of the erectus (the dental alveolus masticatory portion is significant); the strong lower and posterior expansion of the symphyseal region, which differentiates it from rudolfensis and ergaster and Asian erectus and likens it to habilis; the relief of the anterior symphyseal region (sagittal keep, inferior tubercles, parasagittal canine prominences), which distinguishes 2600 from all the hominids considered, except for the small mandible D211 and rudolfensis (ER 1802).; the pronounced protrusion o fparalacteal internal torus mandibularis, which seperates it from habilis, ergaster and all of erectus and equates it with rudolfensis; the marked relief of the internal face of the ascending ramus (crista endocoronoidea, triangular buttress, crista pharyngea and deep triangular fossa for the attachment of temporalis) which differentiates it from erectus and likens it to rudolfensis; the large-sized canines, the P1 crown morphology with a disto-lingual bulge (talonide) and the oblique orientation of the principal axis, the presence of two clearly individualized roots from the neck (mesial and distal root), each of which bears a vertical line, which distinguish D2600 fromthe C and P1 of habilis and ergaster and from most of erectus (the attributes of the P1 in particular are comparable to rudolfensis teeth: ER180 and Malawi UR 501)." |

| Notes: Science mag published an article in Vol 300, 9 May 2003 where most examiners of the Dmansi skulls rejected the new species, citing it was too similar to H. erectus. G. Philip Rightmire (2005) also finds flaws in the strata dates, suggesting tubes had formed and collapsed in the volcanic tuffs, contaminating the older context with the younger Dmansi fossils, arguing that not only is the age younger than previously suspected, but that these specimens are also H. erectus. |
