“…Compared with the Early Jurassic, relatively more silcretes developed in the Late Jurassic in response to the rising global temperature. Late Jurassic silcretes have been reported in Australia, South Africa, France, Canada and Brazil (Al-Ramadan et al, 2005;Du Toit and Reed 1954;Krausse and Mello, 2010;Laity, 2009;Pierini et al, 2010;Twidale and Campbell, 1995;Wopfner, 1978). The Earth continued to warm during the Cretaceous, with average global surface temperature peaking at ~28°C in the mid-Cretaceous (Scotese, 2001;Skelton, 2003;Veizer et al, 2000;Wang et al, 2014;Bata et al, 2015).…”
