Lori and George Schappell, the world's oldest conjoined twins, died April 7 of undisclosed causes, according to a funeral home in Hamburg, Pennsylvania.
The Schappell twins were born in Pennsylvania on September 18, 1961 and were 62 years old when they passed away. They held the record as the longest living conjoined twins and were therefore part of the Guinness World Records.
Before George Schappell came out as transgender in 2007, the twins also held the record as the world's oldest female conjoined twins. After the gender declaration, they became the first to identify with different genders.
The twins in question lived with their heads connected and shared the same skull. They had the same blood vessels and shared 30% of the brain.
Scientists have discovered that they are one of the rarest cases of conjoined twins, accounting for only 2-6% of all cases.
Their heads were together with their faces facing in opposite directions and they could not look at each other. The operation to separate them was not possible when they were born, but they themselves have expressed that they would not want to be separated even if it were possible.
