“…However, climate variability over this geographical area was not very significant in the Late Mesozoic -climate change towards more temperate and humid conditions is reflected by geochemical weathering indices (Ohta et al 2014) with temperatures between 5 o C and 25 o C reconstructed from oxygen isotope data from sedimentary rocks in north-eastern China (Wang et al 2013). However, occasional semi-arid periods are indicated by the appearance of the arid plants Ephedripites and Classopollis in Hong Kong (Lee et al1997), as well as oxygen isotope data from sedimentary rocks in north-eastern China, including from Jilin and Liaoning provinces (Wang et al 2013). Therefore, Paralycoptera most likely lived in areas with a tropicalsubtropical climate similar to many modern osteoglossoids, such as Scleropages formosus (Kottelat 2011).…”

We identify an osteoglossoid teleost fish -Paralycoptera -from Late Jurassic volcaniclastic mudstones from the Lai Chi Chong Formation of Hong Kong, China. This partially preserved postcranial skeleton represents the first Mesozoic fish from Hong Kong and the most southerly Paralycoptera to date. A radiometric date for the Lai Chi Chong Formation of 146 Ma implies a temporal range expansion for Paralycoptera of approximately 40 million years back from the Early Cretaceous (~110Ma). However, spores found in the Formation suggest an Early Cretaceous age that is consistent with the existing age assignment to Paralycoptera. We argue that the proposed temporal range extension is genuine because it is based on recent precise and accurate radiometric data, but given the discrepancies with the biostratigraphic ages further investigation is needed to confirm this. This study provides an important step towards revealing Hong Kong's Mesozoic vertebrate fauna and understanding its relationship to well-studied mainland Chinese ones.

“…Analysis of the SK1 cores taken from the SLB, under the framework of the International Continental Scientific Drilling Program, resulted in several studies on Late Cretaceous paleoenvironmental and paleoclimatic changes using East Asian terrestrial records (e.g., Wang et al, 2013a, Wang, 2013Song et al, 2013;Ji et al, 2015). These systematic investigations indicate a gradual cooling of the SLB from the warmer Albian-Cenomanian through to the end of the Maastrichtian.…”

“…In order to better understand the intracontinental earthquake mechanisms, Chinese scientists started the Wenchuan earthquake Fault Scientific Drilling (WFSD) project just 178 days after the earthquake . The ongoing Continental Scientific Drilling Project of Cretaceous Songliao Basin started in April 2014 and will recover continuous highresolution terrestrial achieves and Cretaceous climate change (Wang et al, , 2013a. Besides these ICDP projects, from 2008 to 2012 the Chinese government also supported the Program of Selected Continental Scientific Drilling and Experiments, which consists of seven drilling projects on some key problems in continental dynamics.…”

Abstract. Continental scientific drilling can be regarded as "a telescope into the Earth's interior" because it provides process insight and uncompromised samples of rocks, fluids, and even sampled from the deep biosphere from the Earth's surface to great depths. As one of the three founding members of the International Continental Scientific Drilling Program (ICDP), ICDP China has made great achievements in many scientific drilling-related research fields. Based on the ICDP participation it attracted global attention of scientists and set up not only the Chinese Continental Scientific Drilling (CCSD) Program in 2001 but also a growing number of ambitious drilling projects in the country.The 5158 m deep borehole of the CCSD project at Donghai County in the Sulu ultrahigh-pressure metamorphic terrain demonstrates that large amounts of crustal rocks of the South China Block have been subducted to at least 120 km, followed by rapid uplift. After successful completion of drilling at Donghai, several continental scientific drilling projects were conducted with funding of the Chinese government and partially with support of ICDP, resulting in a total drilling depth of more than 35 000 m.
