The Taung Skull Fossil Site, part of the extension to the site inscribed in , is the place where in the celebrated Taung Skull — a specimen of the species Australopithecus africanus — was found. Makapan Valley, also in the site, features in its many archaeological caves traces of human occupation and evolution dating back some 3. The area contains essential elements that define the origin and evolution of humanity. Fossils found there have enabled the identification of several specimens of early hominids, more particularly of Paranthropus, dating back between 4. In het fossielgebied Taung Skull werd in de beroemde Taung Skull gevonden; een exemplaar van het fossiel Australopithecus africanus. In hetzelfde gebied ligt de Makapan vallei, waar — in de vele archeologische grotten — sporen gevonden zijn van menselijke bewoning en evolutie daterend van zo’n 3,3 miljoen jaar geleden.

Early Modern Homo sapiens. A ll people today are classified as Homo sapiens. Our species of humans first began to evolve nearly , years ago in association with technologies not unlike those of the early Neandertals. It is now clear that early Homo sapiens , or modern humans , did not come after the Neandertals but were their contemporaries.
However, it is likely that both modern humans and Neandertals descended from Homo heidelbergensis. Compared to the Neandertals and other late archaic humans , modern humans generally have more delicate skeletons.

Griffith University scientists have led an international team to date the skull of an early human found in Africa, potentially upending human evolution knowledge with their discovery. The Broken Hill Kabwe 1 skull is one of the best-preserved fossils of the early human species Homo heidelbergensis and was estimated to be about , years old. Discovered in by miners in Zambia, the Broken Hill remains have been difficult to date due to their haphazard recovery and the site being completely destroyed by quarrying.
The research also suggests that human evolution in Africa around , years ago was a much more complex process, with the co-existence of different human lineages. Professor Stringer said: “Previously, the Broken Hill skull was viewed as part of a gradual and widespread evolutionary sequence in Africa from archaic humans to modern humans. But now it looks like the primitive species Homo naledi survived in southern Africa, H.

Thousands of years ago, people were performing a form of surgery called “trepanation” that involves boring holes through a person’s skull. For a large part of human prehistory, people around the world practised trepanation: a crude surgical procedure that involves forming a hole in the skull of a living person by either drilling, cutting or scraping away layers of bone with a sharp implement. To date, thousands of skulls bearing signs of trepanation have been unearthed at archaeological sites across the world.
But despite its apparent importance, scientists are still not completely agreed on why our ancestors performed trepanation.

The Comparative Anatomy Collection and a subset of specimens from the Atkinson Collection are available to University of the Pacific faculty for teaching and class demonstrations located away from CDHCS but within the dental school building. Use of specimens from the skull collections must take place within designated teaching areas, such as laboratories and classrooms.
In order to minimize potential damage to the specimens, Instructors are expected to provide supervision for student handling of specimens or to read the handling guidelines to the class. Before and after the class, the specimens must be kept behind locked doors, usually in the Instructor’s office, before being returned to CDHCS. As indicated in the loan form, Instructors are responsible for the safekeeping of specimens borrowed from the skull collections.
By signing the Loan Form, the Instructor agrees that it shall be conclusively presumed that the borrowed specimens are in the condition specified in the Loan Condition Report. Using specimens from the skull collections for teaching and class demonstrations within CDHCS is possible. Space for display and viewing is limited by the size of the research table 5’x10′ and the room.

To support our nonprofit science journalism, please make a tax-deductible gift today. Investigators scanned a fragment from the back of an ancient hominin’s skull right and digitally reconstructed it left and center , revealing the rounded skull of Homo sapiens , rather than an elongated Neanderthal skull. In the late s, anthropologists exploring a cave on the rugged coast of southern Greece found two mysterious hominin skull fossils. Time had left them fragmented and distorted, and the jumbled stratigraphy of the cave made them hard to date.
For decades, the fossils sat on a shelf, their identity unknown. Now, a state-of-the-art analysis of their shape together with new dates suggest one skull might represent our own species, living in Greece more than , years ago.

The Hofmeyr Skull is a specimen of a 36, year old human skull that was found in near Hofmeyr , South Africa. It is one of a very few anatomically modern human skulls that have been discovered on the continent which have been dated to over 20, years old. The skull was found in the s on the surface of an erosion gully ,  a dry channel bed of the Vlekpoort River, near Hofmeyr ,   a small town in Eastern Cape , South Africa. No other bones or archaeological artifacts were found in the vicinity at the time of the skull’s discovery.
Others are much more recent, dated to around 20, years ago. He later showed it to Frederick E. Grine then led a detailed study of the skull. It was not possible to date the skull using traditional radiocarbon dating , as the carbon had leached out of the bone. Instead, a new method involving a combination of optically stimulated luminescence and uranium-series dating methods was used.
The method was developed by Richard Bailey of Oxford University. The earth material from the skull “filling the endocranial cavity” central portion of the endocranial cavity was dated using a combination of optically stimulated luminescence and uranium-series dating methods, coupled through a radiation-field model. The dating also assumed that the skull “had neither been uncovered long before nor transported any substantial distance before its discovery”.
Dating the Broken Hill skull: Homo heidelbergensis was younger than we thought
“Do women mind dating with a bald man?” The vast preponderance of women answering this question mentioned being bald is not an obstacle to date. However.
Assuming that they were genuine finds, the hominoid remains were not older than Upper Pleistocene, but it was noted that drill-holes into the teeth revealed that they were “apparently no more altered than the dentine of recent teeth from the soil. Weiner, reviewing this evidence in the light of anatomical considerations, suggested that the mandible was that of a recent ape which had been broken and stained to resemble a fossil, and the teeth artificially abraded to suggest wear through the human type of mastication.
According to his hypothesis, the fraudulent jaw-bone had been placed in the Piltdown gravel pit so as to appear associated with fragments of a thick human cranium of presumed antiquity. Determination of the organic content and re-determination of the fluorine content of these specimens, together with evidence obtained from a detailed anatomical analysis of the teeth, confirmed this hypothesis 3 Table 1. The mandible had the composition of modern bone, whereas the cranial fragments were very slightly ‘fossilized’.
In , the possibility of dating the Piltdown bones absolutely by the radiocarbon method was not seriously considered because it would have involved total destruction of the specimens to provide the minimum quanity of carbon 2 gm. During the past four years, improvement of technique has made it possible to attempt radiocarbon dating on the basis of much smaller quantities.
With the agreement of Dr. White, keeper of palaeontology, powder samples of the Piltdown mandible and right parietal bone were submitted to Prof. Their nitrogen content represents the bone protein collagen.

A partial human skull unearthed in in northern Israel may hold some clues as to when and where humans and Neanderthals might have interbred. The key to addressing this, as well as other important issues, is precisely determining the age of the skull. A combination of dating methods, one of them performed by Dr.

In , in a cave called Apidima at the southern end of Greece, a group of anthropologists found a pair of human-like skulls. One had a face, but was badly distorted; the other was just the left half of a braincase. Researchers guessed that they might be Neanderthals, or perhaps another ancient hominin. By thoroughly analyzing both skulls using modern techniques, Harvati and her colleagues have shown that they are very different, in both age and identity.
The one with the face, known as Apidima 2, is a ,year-old Neanderthal—no surprises there. But the other, Apidima 1, was one of us—a ,year-old modern human. Until now, most researchers have focused on the more complete but less interesting of the two skulls. But its antiquity matters for three reasons. First, it pushes back the known presence of modern humans outside Africa by some 30, years. Collectively, these traits mess up the standard story of Neanderthal and modern-human evolution.
According to that narrative , Neanderthals slowly evolved in Europe, largely isolated from other kinds of hominins. When modern humans expanded out of Africa, their movements into Europe might have been stalled by the presence of the already successful Neanderthals. That explains why Homo sapiens stuck to a more southerly route into Asia, and why they left no European fossils until about 40, years ago.

Kabwe 1 also called the Broken Hill skull , Rhodesian Man is a Middle Paleolithic fossil assigned by Arthur Smith Woodward in as the type specimen for Homo rhodesiensis , now mostly considered a synonym of Homo heidelbergensis. The cranium was discovered in the lead and zinc mine of Broken Hill, Northern Rhodesia now Kabwe , Zambia on 17 June  by Tom Zwiglaar, a Swiss miner , and an African miner whose name was not recorded. The skull was dubbed “Rhodesian Man” at the time of the find, but is now commonly referred to as the Broken Hill skull or the Kabwe cranium.
The skull is kept in the Natural History Museum, London.

Bilateral skull fractures in infancy may result from accidental or abusive injury. Consultation with a child abuse pediatrician may assist with determining the likelihood of accident or abuse. Diagnostic considerations for the infant with bilateral skull fractures are reviewed, including single impact, double impact, and compression mechanisms of injury, as well as the possibility of accessory sutures as skull fracture mimics. Illustrative cases exemplify the evaluative process, including obtaining a detailed history, assessing for the presence or absence of additional physical or radiographic signs of injury, screening for psychosoical risk, and obtaining three-dimensional reconstruction of CT bone images.
An understanding of plausible mechanisms of injury that can result in bilateral skull fractures in infancy can assist with making an accurate determination of likelihood of accident or abuse. Skull fractures in infancy are common in both accidental trauma and inflicted injury. When the mechanism of injury provided on history does not seem to be a plausible explanation of the injurious findings, concern for inflicted injury may lead to child pro-tection agency involvement and an investigation.
Although often suspicious for abuse, some studies support that complex skull fractures, including bilateral fractures, can occur accidentally, 8 , 9 even from a single impact event. This article reviews the diagnostic considerations when evaluating an infant with the finding of bilateral skull fractures. Mechanisms of injury will be discussed, with case examples highlighting the importance of a detailed history and physical exam, the presence or absence of any additional findings or risk factors con-cerning for abuse, as well as a thorough review of radiographic imaging.
Consultation with a child abuse pediatrician may assist in determining if bilateral skull fractures in an infant are consistent with the injury as re-ported on history, or suspicious for abuse. In addition, anatomic variants that mimic fracture will be discussed and should always be considered. Bilateral skull fractures can occur from two direct impact sites, such as two separate blows to the head in inflicted injury.
Revealing the new face of a 3.8-million-year-old early human ancestor
A skull fragment found in the roof of a cave in southern Greece is the oldest fossil of Homo sapiens ever discovered in Europe, scientists reported on Wednesday. Until now, the earliest remains of modern humans found on the Continent were less than 45, years old. The skull bone is more than four times as old , dating back over , years, researchers reported in the journal Nature. The finding is likely to reshape the story of how humans spread into Europe, and may revise theories about the history of our species.
