Revision and description of Keuper (Middle Ladinian to Rhaetian) invertebrate trace fossils from the southern part of the Germanic Basin and studies of related material
… of extended river systems, contain the richest ichnofauna. Trace fossil abundance is generally low and their occurrence is scattered. The studied material can be assigned to 28 ichnogenera, 38 ichnospecies, and 6 vernacular forms. Among the described trace fossils are one new ichnogenus and …

Redefining the Treptichnus pedum zone at the Global Boundary Stratotype Section and Point (GSSP): A critical reassessment of the Ediacaran-Cambrian boundary.
… conduct an ecospace analysis of the section. The ichnofauna reveled a more gradual appearance of ichnofossil diversity at the boundary, and a more protracted transition between Ediacaran and Cambrian ecosystems than previously envisioned. The T. pedum IAZ in the CIF marks the appearance of novel …

Palaeoenvironmental change from the Hettangian to Toarcian in Moyeni (Quthing District), southwestern Lesotho
… desiccation cracks, bone fossils and a diverse ichnofauna (e.g., algal mats, vertebrate burrows, tracks of theropods, ornithischians, amphibians, crocodylomorphs). Sedimentological evidence indicates that in the Hettangian the area was prone to flash floods and drying in a low energy …

Sedimentology, facies architecture, and diagenesis of the Middle Three Forks Formation - North Dakota, U.S.A.
… coupled with an overall low diversity of ichnofauna indicate that basin salinities were elevated at times during middle Three Forks Formation deposition. Bedload transport processes are the dominant mechanism that led to deposition of FA1 and FA2 strata, evident in laminated siliciclastic …

INTERNAL FACIES ARCHITECTURE OF A REGRESSIVE TO TRANSGRESSIVE WAVE-DOMINATED DELTA IN THE UPPER CRETACEOUS EAGLE FORMATION, SOUTH-CENTRAL MONTANA
The Santonian-Campanian Eagle Formation in south-central Montana was deposited along the western margin of the Cretaceous Western Interior Seaway and is composed of a series of well preserved regressive and transgressive deposits. This study documents the depositional evolution of the informal …
