Question: Amenherkhepshef is buried in the tomb in the valley that housed pharaohs from what time frame?

Context paragraphs:
KV13: Tomb KV13, located in the Valley of the Kings in Egypt, was cut and decorated for the burial of the noble Bay of the Nineteenth Dynasty.  An ostraca published in the French Egyptological journal BIFAO in 2000 records that Chancellor Bay was executed by pharaoh Siptah.  Consequently, Bay was never buried in his tomb.  Moreover, no funerary goods were found in the tomb belonging to Bay.  It was later reused by Amenherkhepshef and Mentuherkhepsef of the Twentieth Dynasty.

Amenherkhepshef: The Egyptian prince Amenherkhepshef was the son of Ramesses VI and Queen Nubkhesbed.  He lived in the Twentieth dynasty and was buried in the reused sarcophagus of Twosret, in the reused tomb of Chancellor Bay, KV13, in the Valley of the Kings, on the west bank of the Nile, in Thebes, Egypt.

Sennedjem (18th Dynasty): Sennedjem was a high Ancient Egyptian official living under king Tutankhamun at the end of the 18th Dynasty.  Sennedjem was "overseer of tutors", but also bore several other titles, such as "father of the god, beloved of the god", "fan-bearer on the right side of the king".  Sennedjem is so far only known from his decorated tomb at Akhmim.  The tomb is today heavily destroyed and much of the decoration is lost.  The tomb was never finished and it is uncertain whether Sennedjem was ever buried here.  In the tomb appears several times the name of king Tutankhamun, providing evidence that it was constructed under this king.  In the tomb decoration also appears the "overseer of nurses" Senqed.  The tomb was evidently built for two officials.  It seems that the name of Sennedjem was deliberately erased from the tomb decoration.  Evidently Sennedjem fell out of favour and his memory was deleted.  It is uncertain whether that happened under Tutankhamun or later.

KV11: Tomb KV11 is the tomb of Ancient Egyptian Pharaoh Ramesses III.  Located in the main valley of the Valley of the Kings, the tomb was originally started by Setnakhte, but abandoned when it broke into the earlier tomb of Amenmesse (KV10).  Setnakhte was buried in KV14.  The tomb KV11 was restarted and extended and on a different axis for Ramesses III.

Eighteenth Dynasty of Egypt: The Eighteenth Dynasty of Egypt (notated Dynasty XVIII, alternatively 18th Dynasty or Dynasty 18) is classified as the first Dynasty of the Ancient Egyptian New Kingdom period, lasting from 1549/1550 BC to 1292 BC.  It boasts several of Egypt's most famous pharaohs, including Tutankhamun, whose tomb was found by Howard Carter in 1922.  This dynasty is also known as the Thutmosid Dynasty for the four pharaohs named Thutmosis.

Rapid reaction force: A rapid reaction force is a military or police unit designed to respond in very short time frames to emergencies.  When used in reference to police forces such as SWAT teams, the time frame is minutes, while in military applications, such as with the use of paratroops or other commandos, the time frame is hours to days.

Jamali Kamali Mosque and Tomb: Jamali Kamali Mosque and Tomb, located in the Archaeological Village complex in Mehrauli, Delhi, India, comprise two monuments adjacent to each other; one is the mosque and the other is the tomb of two persons with the names Jamali and Kamali.  The name "Jamali" is Urdu, though originates from "Jamal" which means "beauty".  "Jamali" was the alias given to Shaikh Fazlu'llah, also known as Shaikh Jamali Kamboh or Jalal Khan, a renowned Sufi saint who lived during the pre-Mughal dynasty rule of the Lodi's, a period from the rule of Sikander Lodi to the Mughal Dynasty rule of Babur and Humayun.  Jamali was greatly regarded.  Kamali was an unknown person but associated with Jamali and his antecedents have not been established.  Their names are tagged together as "Jamali Kamali" for the mosque as well as the tomb since they are buried adjacent to each other.  The mosque and the tomb were constructed in 1528-1529, and Jamali was buried in the tomb after his death in 1535.

KV42: Tomb KV42 is an ancient Egyptian tomb located in the Valley of the Kings in Egypt.  It was constructed for Hatshepsut-Meryetre, the wife of Thutmose III, but she was not buried in the tomb.  It was reused by Sennefer, a mayor of Thebes during the reign of Amenhotep II, and by several members of his family.  The tomb has a cartouche-shaped burial chamber, like other early Eighteenth Dynasty tombs.

Memory of Mankind: Several motivations underlie the project.  The primary ambition of MOM is to preserve an image of our era, created by numerous participants all over the planet.  MOM will also contain information which our society is obliged to forward to the future: e.g. description of nuclear waste repositories.  MOM collaborates with the NEA and SKB.  Although the most obvious ambition and often described in the media is the concern about preserving our knowledge, this is not the primary goal of MOM.  Serving as a time capsule MOM is both: in a time frame of millennia it is the story about us, and in a time frame of decades it is a backup.  In times where global warming, nuclear danger and biological warfare threaten the existence of civilization, saving the core knowledge and culture acquired over centuries is a backup measure.  In case of a collapse, the MOM project could help survivors to rebuild civilization.  Linked to this, an another reason is of political order: facing the lack of reactivity of authorities concerning global warming, the MOM project is a reminder of what can happen.  Roman and Greek civilizations whose histories have been reconstructed by the small percentage of texts and artifacts which survived until our days are examples that have inspired the MOM project.  Finally, it's a critic of our digital civilization : according to Kunze, maybe nothing of the 21st century will last in the future, since most of our interactions are now virtual.  The "accuracy versus bullshit" is one of the main themes of the MOM project, worried about loss of information, the project can only aim to save a fragment of the information produced until today, but this fragment has to be representative.
