Skeletal remains of a Pig-nosed Turtle (Carettochelys insculpta) in Tampines Quarry
Location, date and time: Singapore Island, Tampines Quarry; 20 July 2014; 2000 hrs.
Observation: The disarticulated skeleton of a pig-nosed turtle, comprising the skull (without the mandible), fragments of the carapace, and a few limb bones, was found submerged among rocks in the shallow edge of the lake.
Remarks: The cranium, about 8 cm in length, was recovered and will be deposited in the Zoological Reference Collection (ZRC) of the Lee Kong Chian Natural History Museum at the National University of Singapore.
The Pig-nosed Turtle is native to inland waterways of southern New Guinea and the Northern Territory in Australia (Burgess & Lilly, 2014). This species was illegally imported in large numbers and widely available in pet shops in Singapore up until the early 2000s (Goh & O’Riordan, 2007). Free-ranging examples in Singapore are most likely abandoned pets. Ng & Lim (2010) recorded a carcass at MacRitchie Reservoir, and the contributor has observed one in the Eco-Lake at the Singapore Botanic Gardens in October 2013.
