A Late Jurassic freshwater shark assemblage (Chondrichthyes, Hybodontiformes) from the southern Junggar Basin, Xinjiang, Northwest China

Abstract: A low-diversity hybodont assemblage from the Late Jurassic (Oxfordian) Qigu Formation at Liuhuanggou in the southern Junggar Basin includes the remains of three taxa based on isolated teeth, two of which represent new species of a hitherto unknown genus: Hybodus sp. cf. H. huangnidanensis Wang, 1977, Jiaodontus montaltissimus gen. et sp. nov., and Jiaodontus vedenemus gen. et sp. nov. H. sp. cf. H. huangnidanensis might represent a new taxon pending future revisions. The two new species of Jiaodontus gen. nov.… Show more

“…It is closer to morphotype 1b described from the Oxfordian of Northwest China by Klug et al (2010). However, taking into account the diversity of dermal denticle morphology that can be encountered in a single hybodont, as in for example Hybodus delabechei (Reif 1978), it is difficult to say whether this morphotype 2 belonged to a different genus than the other denticles from Phu Noi.…”

“…have all been recovered from freshwater environments (Rees and Underwood 2006;Klug et al 2010), supporting Rees and Underwood's theory that this genus shifted from a marine to a non-marine environment during the Jurassic (Rees and Underwood 2006). This shift seems to be correlated with a reduction in size, as the post-Toarcian teeth do not exceed 15 mm mesio-distally (Xue 1980;Rees and Underwood 2006), whereas Early Jurassic teeth twice that size are not rare (Casier 1959).…”
