“…The supra-acetabular sulcus is a fossa (fossa supra-acetabularis) between the iliac buttress and the acetabular rim in a similar way to SK50, SK3155, to the first representatives of the genus Homo (KNM ER 3228, KNM WT 15000) to African fossil samples from the lower and middle Pleistocene (OH 28 and Broken Hill E 719) and finally to the European Neandertals 96,72 . Most Pleistocene hominins are thought to have a supra-acetabular sulcus/fossa, including Arago XLIV, OH 28, Skhul IV, and most Neandertal hip bones, including Krapina, Amud 1, La Chapelle-aux Saints, La Ferrassie I, Hortus XLV, Neandertal 1 and Sima Pelvis 1 96 . Rarely, some Australopithecus (e.g., Sts 14, TM-1605, SK 50) and some modern humans show a supra-acetabular fossa 96,72 .…”

“…Finally, there is a thickening of the bone above the acetabulum which corresponds to the very base of the Anterior Inferior Iliac Spine (AIIS) in both C16b and Omo1. The iliosciatic buttress, consisting of the surface that extends from the arcuate line to the deepest portion of the greater ischial notch, shows in C16a and b a robust pillar-like morphology as in Krapina 207 96 . Among fossils, iliosciatic morphology is variable: narrow and pillar-shaped (SK 3155, SK 50, Arago 44, AT-Pelvis 1, AT-800), broad and flat (AL 288-1), and intermediate (Sts 14, KNMER 3228, OH 28, AT3807-3809, AT3300 and AT1004) 96 .…”

The characters detected on C16a and b, which in summary consist of a probable oblique auricular surface (C16b), a laterally flared iliac blade (C16b) and robust acetabulocrystal, acetabulosacral and iliosciatic buttresses, could also be among the traits characterizing H. erectus 97 .…”

“…C16a has a height of the iliac buttress (79.0mm) lower than Krapina 207 (90.9mm) while the thickness is greater (19.5mm in C16a and 12.4mm in Krapina 207). C16 a and b differ in thickness and the presence of an analogy between C16b, and Omo 1 emerges 96 . The iliac thickness measured at the greater sciatic notch is: 23.3mm in C16b, 22.7mm in Omo 1 and 20.7mm in C16a; the ilium, at the base of the auricular surface, has a thickness of 27.3mm in C16b, 26.4mm in Omo1 and 25.7mm in C16a.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.
