A hominid tooth from Bulgaria: the last pre-human hominid of continental Europe.
A hominid upper premolar was discovered in the Azmaka quarry, near Chirpan (Bulgaria). The associated fauna, especially the co-occurrence of Choerolophodon and Anancus among the proboscideans, and Cremohipparion matthewi and Hippotherium brachypus among the hipparions, constrains the age of the locality to the second half of the middle Turolian (ca. 7 Ma), making it the latest pre-human hominid...
متن کاملNew estimates of early hominid body size.
Body weights for 12 early hominid specimens are estimated based on an analysis of four variables shown to have high correlation with body size in living Old World primates. Average size estimates of around 36 kg are suggested for gracile early hominids and around 59 kg for robust early hominids. Size variation is considerably more pronounced in the robust group than in the gracile group, sugges...
متن کاملHypoglossal canal size and hominid speech.
The mammalian hypoglossal canal transmits the nerve that supplies the motor innervation to the tongue. Hypoglossal canal size has previously been used to date the origin of human-like speech capabilities to at least 400,000 years ago and to assign modern human vocal abilities to Neandertals. These conclusions are based on the hypothesis that the size of the hypoglossal canal is indicative of sp...
متن کاملEarly pliocene hominid tooth from Galili, Somali Region, Ethiopia.
A fossil hominid tooth was discovered during survey at Galili, Somali region, Ethiopia. The geological and faunal context indicate an Early Pliocene age. The specimen (GLL 33) consists of an almost complete lower right third molar likely representing a male individual of advanced age-at-death. Its comparative metrical, morphological and (micro)structural analysis (supported by a microtomographi...
متن کاملTooth size discrepancies in an orthodontic population.
OBJECTIVE To explore how many millimeters of tooth size discrepancy (TSD) are clinically significant, to determine what percentage of a representative orthodontic population has such a tooth size discrepancy, and to determine the ability of simple visual inspection to detect such a discrepancy. MATERIALS AND METHODS The sample comprised 150 pretreatment study casts with fully erupted and comp...
