Voltziopsis, a southern conifer of lower Triassic age
Papers and proceedings of the Royal Society of Tasmania, 1967 Shoots ascribed to Voltziopsis africana Seward are described, with cuticular detail. These compare very closely with the shoot system, with an attached seed cone, caned V. wolganensis sp. nov., which is associated with pollen of the Strotersporites Wilson sort.

Geological Journal, EarlyView.New zircon ages reveal that lacustrine sedimentation initiated in the Late Miocene (Messinian), revising earlier Pliocene age assignments. The study results support the interpretation of the northern BFSZ as a broad left‐lateral transtensional shear zone rather than a discrete sinistral fault or simple extensional graben array.

Triassic beds in the basement of the Adriatic-Dinaric carbonate platform of Mt. Svilaja (Croatia)
Geologija, 2003 On the southwestern slope of Mt. Svilaja a Triassic sequence is exposed. It is composed of Lower Triassic carbonate siliciclastic shelf beds that are unconformably overlain by Anisian breccia.

Diagenesis and reservoir quality of the Lower and Middle Buntsandstein (Lower Triassic), SW Germany
, 2015 This research work deals with the diagenesis and reservoir quality of the Lower Triassic Buntsandstein in south-western Germany. The Buntsandstein in the study area is a continental succession with mostly fluvial and subordinately lacustrine and aeolian sediments.

Palaeogeography, Palaeoclimatology, Palaeoecology, 1995 Paleoecologic study of invertebrate faunas from three successive Early Triassic seaways reveals that biotic recovery from the end-Permian mass extinction event was slow, and that full recovery did not occur until after the Early Triassic. Simple, cosmopolitan, opportunistic generalists, and low-diversity, low-complexity paleocommunities were ...

Geological Journal, EarlyView.The rhyolitic ignimbrite and K‐feldspar granite porphyry from the Wangmushan mining district, northern Fujian yield ages of 173.8 ± 0.8 and 102.6 ± 0.4 Ma, respectively. Geochemical data, zircon trace elements, whole‐rock Sr–Nd–Pb isotope data, and zircon Hf isotopic compositions indicate that the rhyolitic ignimbrite originated from partial remelting ...

Triassic Deposits of Hrvatsko Zagorje
Geologia Croatica, 2010 In the area of Hrvatsko Zagorje, Triassic deposits crop-out in theform of tectonic emplacements, forming the cores of all the majormountains. They also underline Neogene deposits, as proven in numerousboreholes.During the Triassic period, continuous ...
