Discussion of Yang et al. (2017, Acta Geologica Sinica 91:749–750) A new discovery of the Early Cretaceous supercritical hyperpycnal flow deposits on Lingshan Island, East China

Tettagalma striata, new genus and species of Tettigarctidae (Hemiptera: Cicadoidea), is described from the Lower Cretaceous laminated limestones of the Crato Formation, Brazil. The new discovery represents the first certain record of this family in Brazil and confirms its presence in the Southern Hemisphere during the early Cretaceous. Architettix Hamilton, 1990, from the same formation, and all the taxa originally placed in Cicadoprosbolidae, are also included in Tettigarctidae, as the former is considered a synonym.

New Discovery

A new fossil salamander,Nuominerpeton aquilonaris(gen. et sp. nov.), is named and described based on specimens from the Lower Cretaceous Guanghua Formation of Inner Mongolia, China. The new discovery documents a far northern occurrence of Early Cretaceous salamanders in China, extending the geographic distribution for the Mesozoic fossil record of the group from the Jehol area (40th–45th parallel north) to near the 49th parallel north. The new salamander is characterized by having the orbitosphenoid semicircular in shape; coracoid plate of the scapulocoracoid greatly expanded with a convex ventral and posterior border; ossification of two centralia in carpus and tarsus; and first digit being about half the length of the second digit in both manus and pes. The new salamander appears to be closely related to hynobiids, although this inferred relationship awaits confirmation by research in progress by us on a morphological and molecular combined analysis of cryptobranchoid relationships. Comparison of adult with larval and postmetamorphic juvenile specimens provides insights into developmental patterns of cranial and postcranial skeletons in this fossil species, especially resorption of the palatine and anterior portions of the palatopterygoid in the palate and the coronoid in the mandible during metamorphosis, and postmetamorphic ossification of the mesopodium in both manus and pes. Thus, this study provides a rare case study of developmental features in a Mesozoic salamander.
