New Triassic Insect from Kyrgystan and a New Species of Palaeoxyris from Germany

Béthoux, O., Voigt, S., and J. W. Schneider. 2010. A Triassic palaeodictyopteran from Kyrgyzstan. Palaeodiversity 3: 9–13.

Abstract - A specimen belonging to the species reliquia n. sp. is described from the Dzaylyaucho locality (Madygen, Kyrgyzstan; late Middle to early Late Triassic). It is interpreted as a palaeodictyopteran. It is therefore the latest occurrence of this group, previously considered as extinct during Middle to earliest Late Permian.

Böttcher, R. 2010. Description of the shark egg capsule Palaeoxyris friessi n. sp. From the Ladinian (Middle Triassic) of SW Germany and discussion of all known egg capsules from the Triassic of the Germanic Basin. Palaeodiversity 3: 123–139.
Abstract - The new shark egg capsule Palaeoxyris friessi n. sp. is described from the Hauptsandstein of the Lower Keuper (Erfurt Formation, Ladinian, Middle Triassic). The type and only specimen is complete and remarkably well preserved. With a length of 27 cm it is the longest complete Palaeoxyris egg capsule known so far. It is interpreted as an egg capsule of the hybodontid sharks Polyacrodus polycyphus or cf. Polyacrodus keuperianus. The capsule is associated with a rich flora, the brackish water bivalve Unionites and conchostracans, but other vertebrate remains were absent. All known records of Triassic and Lower Jurassic egg capsules from the Germanic Basin and their potential producers are discussed. All of the capsules have been found in deltaic or prodeltaic deposits.
