 Homo floresiensis


Synonyms:
 Homo erectus floresiensis

Homo floresiensis would be assigned to Homo erectus floresiensis using the Fossilized.org alpha taxonomy

Original diagnosis:"Small-bodied bipedal hominin with endocranial volume and stature similar to, or smaller than, Australopithecus afarensis.   Lacks masticatory adaptations present in Australopithecus  and Paranthropus, with substantially reduced facial height and prognathism, smaller postcanine teeth, and posteriorly orientated infraorbital region.  Cranial base flexed.  Prominent maxilllary canine juga form prominent pillars laterally separated from nasal aperture.  Petrous pyramid smooth, tubular and with low relief, styloid process absent, and without vaginal crest.  Superior cranial vault bone thicker than Australopithecus and similar to H. erectus and H. sapiens.  Supraorbital torus arches over each orbit and does not form a flat bar as in Javan H. erectus.  Mandibular lower P3 with relatively large occlusal surface area, with prominent protoconid and broad talonid, and either bifurcated roots or mesiodistally compressed Tomes root.  Mandibular lower P4 also with Tomes root.  First and second molar teeth of similar size.  Mandibular coronoid process higher than condyle , and the ramus has a posterior orientation.  mandibular symphysis without chin and with a posterior inclination of the symphysial axis.  Posteriorly inclined alveolar planum with superior and inferior transverse tori.  Ilium with marked lateral flare.  Femur neck long relative to head diameter, the shaft circular and without pilaster, and there is a high bicondylar angle.  Long axis of tibia curved and the midshaft has an oval cross-section"  (Brown et al: 1055). Stands approximately 1 meter tall, with cranial capacity approximating 380 cc (1055).

Notes: Having `thin' enamel. However, enamel thickness is a complex character and intraspecifically variable, and its within-tooth three- dimensional patterning is characteristically expressed both serially ALA-VP-2/10 (Fig. 1) is a right mandibular corpus with M3, left I2, C, P4, M2 and M3 root fragment. Holotype and referred material are housed at the National Museum of Ethiopia, Addis Ababa. Holotype from Alayla Vertebrate Paleontology Locality Two (ALA-VP 2); differentially corrected GPS coordinates 108 16.4839 N and 408 15.3139 E; elevation 690 m. Recovered in Sept. 2003 within an area roughly 5 meter squared area.  Portions of the skeleton were still articulated.  Skeleton is not fossilized, thus very fragile.  Arms may still be contained in wall of excavation unit, thus may be recovered in the future.  Dentition indicates specimen is an adult; pelvis indicates specimen is female.  AMS calibrated dating yields approximate dates of "18 kyr and bracketed by luminescence dates of 35 +/- 4 kyr and 14 +|- kyr" (1055).   Discovered east of the Wallace line.  Small size of this population may be due to "thermoregulatory advantages for life in a hot and humid forest, either through evaporative cooling or reduced rates of internal heat production....stature and brain size inconsistent with insulin-like growth factor 1 (IGF-1)-related post-natal growth retardation...pituitary dwarfish and primordial microcephalic dwarfism (PMD) in modern humans replicates skeletal features present in LB1" (1059-1060).

Fossilized.org presents precise geographic locations and current best date estimates for late Miocene, Pliocene, and Pleistocene sites with human ancestor (hominin) fossils and archaeology. Several interactive visual interfaces allow users to generate maps and tables that relate localities, fossils, tools, and evolutioanry events with geography and time. The data content is dynamic and is updated daily, as are new interface features. This site started as a course syllabus for Anthropology 3101: Human Evolution 2 at California State University, East Bay, and grew with each quarter it was used. Now fossilized.org has over 200 sites and hundreds of bibliographic citations.
