A skull long assumed to be from Arsinoë IV , Cleopatra ’s half sister , is actually from an adolescent boy who had a transmissible disorder , according to investigator . In a new study , the compounding of CT scans andDNAanalysis has proved once and for all that the systema skeletale , which was discovered in Turkey a century ago , was not Arsinoë .

In 1929 , a skeleton was found in a marble sarcophagus in a building scream the Octagon at Ephesus , an archaeological internet site in Turkey that boasted a monolithic tabernacle to Artemis , the ancient Grecian goddess of the hunt club . There were no serious goods or inscriptions , but archaeologists at the fourth dimension concluded that the burial was made for an authoritative young woman . They guess that the occupier of the tombmight have been Arsinoë IV , who took up arms against her half sister andJulius Caesarand led the Siege of Alexandria in 48 to 47 B.C. Arsinoë and her troops lost that battle , and she sought asylum at the Temple of Artemis in Ephesus . In 41 B.C. , when she was 22 years old , Marc Antony ordered Arsinoë ’s slaying .

In a work publish Friday ( Jan. 10 ) in the journalScientific Reports , a team of researchers reinvestigated the possibleness that the skull recovered a hundred ago was Cleopatra ’s half baby . Theirradiocarbon analysisof the stiff place the person ’s date of death between 205 and 36 B.C. , which aline with Arsinoë ’s historically recorded death . However , the skeletal system ’s phase of growing suggested the someone was just 11 to 14 years old — much young than Arsinoë .

" But then came the big surprise , " study jumper cable authorGerhard Weber , a prof of evolutionary anthropology at the University of Vienna , said in astatement . " In repeated tests , the skull and femur both clear showed the bearing of a Ychromosome — in other words , a male . "

Because the skull pearl were thinner and more slight than expected , the investigator further investigated the skeleton and let out misshapenness that had not been noticed previously .

One of the cranial sutures — the wiggly lines on a skull where the individual bones fuse during living — was already close , which does not normally go on until a person is older than 65 . Early closure of this cranial suture cause the male child ’s skull to be asymmetrical .

More spectacular , the researchers noted in their sketch , was the person ’s abnormally shaped upper jaw , coupled with at least one tooth that had no evidence of wear . Both of these feature suggest that the son had a misfunction upper jaw and potentially a small , abnormally oriented lower jaw .

One potential account for these skull and jaw trait is a rare genetic upset calledTreacher Collins syndrome(TCS ) , according to the researchers . This condition affects the development of the fount and head , causing a modest jaw , downwards - slanting eyes , and earshot and vision problems . Although the team attempted to apply genetical analytic thinking to identify TCS in the adolescent boy , the surviving segment of DNA were insufficient to prove it .

But why this son with developmental disturbances was buried in the prominent Octagon at Ephesus site stay a mystery , the researchers wrote in the subject field .

" What we can now say with certainty is that the someone buried in the Octagon was not Arsinoë IV , and the hunting for her remains should continue , " they concluded in the field of study .
