Renewed survey at fossil #hominin sites sometimes turns up additional fragments of earlier discoveries. The LH 5 fragmentary maxilla and dentition of Australopithecus afarensis has parts that were discovered in 1974 and 1979, up to 49 meters apart. #paleoanthropology

Zhoukoudian was not the first discovery place of Homo erectus, but thanks to the work of Franz Weidenreich in the 1930s and 1940s, it became the prototype for the way later scientists understood this #hominin. One reason was his reconstruction of the L2 skull. #paleoanthropology

Krapina 4 is a fragmented skull of a Neandertal from around 120,000 years ago. This #hominin individual suffered a blunt force trauma to the left forehead, resulting in soft tissue infection of the area. Some healing happened prior to the individual's death. #paleaonthropology

The femur and tibia from locality 129 were the first clear evidence of bipedal #hominin fossils from Hadar, Ethiopia, in 1973. The strong lateral angulation of the femur shaft is a distinctive aspect of bipedal locomotion in humans and our fossil relatives. #paleoanthropology

The 1959 discovery of the OH 5 #hominin skull led to the first K-Ar age determination of sediments at Olduvai by Garniss Curtiss. Finding them to be 1.75 Ma—triple the expected age—he wrote: "One thing is certain. Olduvai Man is old, old, old!" #paleoanthropology #FossilFriday

An approximately 1.9-million-year-old #hominin fossil from Swartkrans, South Africa, attributed to the genus Homo is one of the first to have dental abcesses, which affect the tips of its incisor roots. #paleoanthropology

The most well-preserved evidence of the brain of #Homonaledi comes from the DH3 partial skull. At 450 ml, this #hominin fossil's endocranial volume is around one third the size of the average living human, but shares some aspects of frontal lobe form. #paleoanthropology

A 2013 analysis by @AlmecijaSergio and coworkers put the Orrorin femur into context of Miocene apes, fossil hominins, and living apes. Chimpanzees and gorillas diverge strongly in their femoral morphology from their close living and fossil relatives.

Skull 3 from Dmanisi is one of the most complete cranial remains attributed to Homo erectus. This #hominin individual represents a stage of development just before adulthood, with third molars just beginning to erupt. #paleoanthropology

Recent work by Yolanda Fernández-Jalvo and Peter Andrews found that cranial fractures on the Spy 1 Neandertal skull were the likely cause of death of this #hominin individual. A new dating scheme places the Spy Neandertals between 44,300 and 40,700 years ago. #paleoanthropology
