Egyptian Prime Minister Ibrahim Mahlab inaugurated the newly renovated Animal Museum at Giza Zoo on Monday.
Built in 1914, the three-storey building is home to a large assortment of mummified birds and reptiles, skeletons, as well as collectables from fishing trips taken by King Farouk of Egypt and Abdulaziz Al-Saud, Saudi Arabia's founder and first monarch.
The museum boasts the earliest mummified crocodile which dates from 4,000 BC, as well as over 1,300 embalmed birds and dozens of skulls.
Also on Monday, a delegation of Saudi veterinarians paid a visit to the newly revamped facility.
Located near the west bank of the Nile and set in around 80 acres, the 124-year-old zoo was once one of the world's foremost zoological gardens, but has since fallen into disrepair.
Animal rights campaigners have long called for better animal care at the site.
