Cymatosaurus is an extinct genus of pistosauroid or nothosauriform sauropterygian. It is known to have been alive from the Early Triassic to the Middle Triassic period (latest Olenekian to Anisian stages) of Germany and they seem to originate from the Netherlands. It was small to medium-sized for an eosauropterygian, measuring long. thumb|left|Cymatosaurus and pachypleurosaur humeri

Yuanansuchus is an extinct genus of mastodonsauroid temnospondyl. Fossils have been found from the Xinlingzhen formation in Yuan'an County, Hubei, China and date back to the Anisian stage of the Middle Triassic.

Pleuromeia is an extinct genus of lycophytes related to modern quillworts (Isoetes). Pleuromeia dominated vegetation during the Early Triassic across Eurasia and elsewhere, in the aftermath of the Permian–Triassic extinction event. During this period, it often occurred in monospecific assemblages. Its sedimentary context in monospecific assemblages on immature paleosols is evidence that it was an opportunistic pioneer plant that grew on mineral soils with little competition. It spread to high latitudes under greenhouse climatic conditions.

Xinminosaurus is an extinct genus of cymbospondylid ichthyosaur known from the Middle Triassic (mid-late Anisian stage) of Guizhou Province, China.

Cleithrolepis is an extinct genus of freshwater ray-finned fish that lived from the Induan age (Early Triassic epoch) to the Anisian (Middle Triassic) in what is now Australia (New South Wales, Tasmania) and Libya. A species from Late Triassic Germany, C. brueckneri, was also ascribed to Cleithrolepis.
