Chinese White Dolphin Stuck in Pearl River Tributary

Wildlife experts in south China are trying to rescue an endangered Chinese white dolphin (Sousa chinensis) that is in worsening health after swimming into a tributary of the Pearl river a week ago. The dolphin is approximately 30 years old and swam into the Baisha Rivernear Jiangmen in Guangdong Province on the 1st of February. It is now in a stretch of water about 100 km from the sea. “[…] the skin of the dolphin is festering and its health is deteriorating … its moving area is shrinking,” said Feng Kangkang, a worker with Jiangmen Chinese White Dolphin Nature Reserve, on Thursday. The team is watching the dolphin around-the-clock and recording its health condition, according to the Guangdong provincial ocean and fishery department. Dubbed the “giant pandas of the sea” by some, the Chinese white dolphins are mainly scattered in a few coastal areas where they exist in small numbers. About 2,000 are known from areas around the Pearl River, including HK which at the last count, was down to about 60 dolphins. (Photo/Xinhua)

HKU Student Identifies Dinosaur-Era Fish in Sai Kung Rocks

A Hong Kong University (HKU) student is said to have identified a Jurassic fish from Lai Chi Chong after studying some fossil collections at the university‚Äôs Stephen Hui Geological Museum.

Edison Tse Tze-kei found the specimen by chance as he was doing a research project in his final year of undergraduate study during the 2013-14 academic year, according to an announcement from HKU.

The fish, which is believed to date back to around 147 million years, represents the first dinosaur-era vertebrate specimen identified in Hong Kong, the university said in a statement posted on its website Thursday.

   

 

Tse, a graduate of the class of 2014, completed the research, description and identification under the supervision of three professors, including Michael Pittman, Research Assistant Professor and Head of the Vertebrate Palaeontology Laboratory at HKU.

The research results will now be published in PeerJ, an open access, peer-reviewed, scholarly journal of biological and medical sciences, by the end of this month.

The fossil specimen was found at Lai Chi Chong in Sai Kung, which is within the Hong Kong Geopark area, and was kept at a HKU museum.

The Jurassic fish was an osteoglossoid teleost fish, which is also referred to as Paralycoptera.

 

The preserved skeleton represents the first of such fish species from Hong Kong and the most southerly Paralycoptera identified to date, meaning that the activity area of the fish could be larger than scientists had first estimated.

Matthew Sin, a spokesperson for local NGO Green Power, said some visitors to Lai Chi Chong may have taken away rocks as souvenirs.

He reminded people that taking any sedimentary rocks, fossil, mineral or even sand samples from the Geopark is illegal.
