History
The specimen was discovered by Josep Gibert in 1982[3]-1983 at Venta Micena, one of several paleo-archaeological sites in the municipality of Orce, Granada, Spain.[4] It was labelled hominid 2 or VM-0 after being freed from sediment by Gibert, Jordi Agustí, and Salvador Moyà-Solà. This team was young and established experts in various fields except paleoanthropology, and took the fragment to Barcelona, which funded the Sabadell Institute of Paleontology and thus their research. They enlisted the paleontologists Rafael Adrover, Pierre Mein, and Peter Andrews for taxonomic identification, and they agreed that the specimen was human.
At this time, the endocast of the vault remained attached to rock, but Gibert's team insisted that the portion cleaned was enough to publish it on May 1983 as the oldest human in Europe, sending it to the Granada press. This sparked scientific interest in Gibraltar as the entrance point into Europe. During another excavation of the same year, they invited Marie-Antoinette and Henry de Lumley to study it, suggesting a hominin identity. The team became very prestiged, planning several lectures and a book on the find, as well as writing articles. Marie-Antoinette de Lumley's conclusions influenced Agustí and Moyà-Solà, but not Gibert.[1]
Criticism and media frenzy
From October 1983 through April 1984, further preparations revealed a ridge in the endocast of the upper squame on the
Gibert formed a team to prove their classification as Homo, including Agustí, Moyà-Solà and faunal expert Bienvenido Martínez (who had earned a PhD from Gibert) among many others. In total, they wrote 138 publications, including 12 in impact journals in an attempt to circulate his ideas and credibility. He also attended a conference and was met with little backlash, but M.-A. de Lumley attended a separate conference and criticized his work without his presence. Agustí and Moyà-Solà published an article accepting Equus as the identification. In 1995, a conference hosted by Gibert agreed with his findings, leading to a brief period of acceptance followed by statements by José María Bermúdez de Castro and Eudald Carbonell of Atapuerca suggesting that he is not scientifically rigorous.
Baruzzi (2013) note that during this controversy, Gibert maintained an eccentric and unorthodox attitude heading a paradigm shift in human evolution as a sort of revolutionary. Gibert's team broke again, with former members affirming taxonomic allocation to Equus and excavating the site. However, a directorial resignation from the Institute and newfound discussion over the specimen led to excavations being halted.[1]
Aftermath
Baruzzi suggests that politicians involved in such a media scandal were influenced by the media and were given the power to influence scientific research. As well, Gibert held considerable power in Orce as 'adoptive son of the town' and namesake of the local museum, formerly called the Orce Museum. Since he was considered prestigious locally, Baruzzi suggests that the Orce Man scandal was an attempt to sully his image, and that the media frenzy lessened in 1999. Gibert spent the remainder of his life defending his taxonomic classification of the fragment until his death in 2007 due to lymphatic cancer. Campillo (2006) discovered the skull of a Roman girl and Gibert noted Homo erectus sporting a similar crest. Discussion through media was also newfound, making science easier to engage with and quicker for scientists and the public.[1] Sanchez (2012/2013) used the informal name "Homo orcensis" for VM-0 in a photo caption.
Description
Baruzzi identifies multiple causes for concern in identification of the skull. First is the crest along the

Moyà-Solà and Köhler (1997) suggest that many of Gibert and team's observations are objectable, most prominently the interpretation of the sutures. They suggest that it is Equus altidens based on how common fossils of this species are at Venta Micena. Additionally, they call for scientists to consider that it is more likely that it is an ordinary equine than a hominin exhibiting rare morphological combinations and pathologies, and that it is flawed "wishful thinking" otherwise.[2]
Subsequent discoveries
Hominin occupation at Orce is generally uncontested because genuine evidence has come to light since the discovery of cranial fragment VM-0.

Barranco León artifacts
Oldowan tools, 1244 (26 cores, 185 whole flakes, 78 flake fragments, 759 debris, 17 retouched, 92 angular fragments, 12 various modified cobbles, and 75 unmodified cobbles), were reported from the 1.4 mya-old Barranco León site in 2013. these tools were produced with flint, quartzite, and limestone, and most raw material was probably originated from Jurassic deposited 3 kilometers south of the site or secondary alluvial/colluvial deposits near the site. They knapped using hard-hammer percussion and direct unipolar and bipolar techniques, coordinated with the texture and quality of the rock. They seem to have prioritized small flakes for immediate use in cutting large carcasses. Striations and polishes are similar to Olduvai, Koobi Fora, and Monte Poggiolo, which indicates use on a variety of materials. Spiral or helical fractures, impact points, flake scars, and bone flakes were discovered on megafaunal remains and are associated with the tools.[6]
