The anthropologist also found an old incised wound on Philip's left hand caused by a sharp-edged object, possibly a weapon.
Degenerative lesions and markers pointed to a middle-aged man who rode a horse frequently.
Examination of the bones revealed a fully-fleshed cremation, further disproving the theory that the remains belong to Philip III Arrhidaeus, who was buried, exhumed, cremated and finally reburied.
"Features such as cracking, color, warping, twisting seen on the bones indicate pyre-induced morphological alterations," Antikas said.
"A typical example is the 90-degree twisting of the left parietal bone of the man's cranium. This would never happen, if the skull were 'dry', coming from an ossuary," he added.
Additional composite material was also found on the bones. Dr. Yannis Maniatis, Head of the Archaeometry Lab at the ''Demokritos'' National Scientific Research Center in Athens, Antikas's team found traces of royal purple, huntite, textile, beeswax and clay belonging to an elaborately made object.
"It was placed on top of the bones after they were cleaned, wrapped and placed in the gold larnax. If they had been burned in the pyre, they would have dissappeared, as its temperature exceeded 800 degrees Celsius at times," Antikas said.
Ongoing investigations carried by Maniatis might reveal the nature and origins of the puzzling composite material. According to the researchers, further evidence for the dead being Philip II is the identity of the female buried in the antechamber, who died at 30 to 34.
"Her age was determined by examining a pelvis bone fragment not seen or identified by previous researchers," Antikas said.
The finding proved extremely important in the complex identification process.
"Basically her age excludes every other wife-concubine of Philip II and indirectly Arrhidaeus, whose wife was under 25," he said.
Morphological alterations in the bones indicate she was cremated just after her death, just like the deceased in the chamber, while equestrian activity indicators suggest she also rode for a long time.
A fracture in the upper end of her left leg caused shortening, atrophy, "and most probably disfiguration," according to Antikas.
"This leads to the conclusion that the pair of mismatched greaves -- the left is shorter -- the Scynthian gorytus and weaponry found in the antechamber belonged to her," he said.
The finding reinforces the assumption made by Hammond as early as 1978 that the spears, arrows, quiver and greaves belonged to a warrior queen in Philip's royal household. Among the candidates proposed by Hammond were Meda, Cynna (the offspring of Philip and Audata, an Illyrian warrior princess) and an unknown daughter of the Scythian king Ateas, defeated by Philip in 339 B.C.
The Scythian theory also strengthens Philip II's identification.
"No Macedonian King other than Philip is known to have had 'relations' with a Scythian," Antikas said.
According to Adrienne Mayor, a research scholar at Stanford University's Departments of Classics and History of Science, the new bioarchaeological analysis of the bones in Tomb II "is a truly exciting discovery, confirming without a doubt that the weapons and mismatched greaves belonged to a horsewoman-archer close to Philip II."
The author of "The Amazons: Lives and Legends of Warrior Women across the Ancient World," Mayor, however, cautions about the Scynthian princess hypothesis.
"Hammond speculated that Ateas might have sent a daughter to Philip during their negotiations. But their dealings were hostile, not friendly, ending in war and the defeat of Ateas in 339 B.C.," Mayor told Discovery News.
"Moreover, as Hammond acknowledged, there is no mention of a daughter of Ateas in any ancient sources that describe Philip's interactions with Ateas or list the names of his wives," she added.
Mayor proposes another possibility -- that the mystery woman could have been a wife selected by Philip from the 20,000 Scythian women he took as prisoners after the defeat of Ateas. The sources report that these women and their horses all escaped when another Scythian tribe attacked Philip's army on its way back to Macedonia.
"Perhaps one of these women, traveling with Philip's entourage, did not escape and remained in the royal house for three years until his death in 336 B.C. When the king was assassinated, a captive Scythian bride from Ateas' coalition may well have felt compelled to commit suicide," Mayor said.
On another finding, Antikas' team shed new light on the remains in Tomb I. His team found in an old storage place with wood cases containing plastics bags filled with never-studied bones from the tomb, which was thought to contain the remains of a male, a female and an infant. This led some scholars to believe Tomb I contained the remains of Philip, his wife Cleopatra, and their few-week-old child.
"From three recently found plastic bags containing over one hundred bone fragments of inhumed individuals, our team analyzed and identified 70 bones," Antikas told Discovery News.
Surprisingly, it emerged that Tomb I contained the remains of at least seven individuals: an adult male, a female, a child, four babies aged 8-10 lunar months and one fetus of 6.5 lunar months.
"This find automatically disproves every previous hypothesis of historians and archaeologista alike that Tomb I was intended for Philip II and his last wife," Antikas said.
