The Ayala Hall holds four important exhibits. First of which is a breakthrough in the field of paleoanthropology which proved early human activity more than 700,000 years ago. The evidence unearthed in Kalinga Province are the fossilized remains of the Nesorhinus philippinensis and stone tools. It is believed by researchers that early humans used stone tools to get the bone marrow of the rhinoceros.
Also in the Ayala Hall are the “Ammonite Mollusk”, an index fossil used as a basis in establishing geological periods. The Conus gloriamaris, also known as the “Glory of the Sea Cone”, was once believed to be one of the rarest types of shell in the world.
Lastly, upon entry, up in the ceiling is the hanging skeleton of “Lolong” ”, the former Guinness World Records holder as the largest saltwater crocodile in captivity from September 3, 2011 until his death on February 10, 2013.
