Stratigraphy
| Formation: | Pielach | ||||
| Local section: | Kendl | ||||
| Regional section: | Molasse | ||||
| Stratigraphic resolution: | group of beds | ||||
| Stratigraphy comments: STRATIGRAPHY: The section starts with about 1 m blueish to brown clay and silt with rootled beds. A rich macrofossil assemblage appears at the top of the overlying silty/sandy part of about 2 m thickness. Up to 1 m silty sand follows, with abundant gastropods. AGE: The Pielach Formation can be dated o the lower Polle Bozone Ng. Z. 1., ranging from the Kiscellian to the Early Egerian. The Early Egerian age can be inferred for the upper part of the Pielach Formation, based on its interfingering with the Melk and Linz Formations. Assigned here to Late Kiscellian-Early Egerian = Chattian. | |||||
Lithology and environment
| Primary lithology: | shelly/skeletal lithified silty sandstone |
| Includes fossils? | Y |
| Lithology description: Silty/sandy unit with rich molluscan fauna, overlain by silty sand with abundant mollusca. Lithification not mentioned in text, but assigned on the basis of photographic plates - some specimens of which are clearly derived from lithified sediment. | |
| Environment: | lagoonal |
| Glacial or sequence phase: | transgressive |
| Geology comments: Overlies fluvial-estuarine facies, as indicated by rooted beds and coal lenses. Upsection macrofauna suggests marine influence, littoral environments, a community indicating lagoonal, brackish conditions. Mesohalie or even polyhaline salinities are probable for the fauna. The fauna of the overlying beds reflects and increase in salinity and a gradual shift from the littoral to the sublittoral. | |
Taphonomy
| Modes of preservation: | body |
| Size of fossils: | macrofossils |
| Preservation of anatomical detail: | medium |
Collection methods and comments
| Collection excludes: | all microfossils |
| Collection methods: | selective quarrying,field collection,survey of museum collection |
| Reason for describing collection: | taxonomic analysis |
| Collection method comments: Lists obtained from previous accounts and material obtained from collections at Inst. of Pal. Vienna, Geol. Surv. Austria Vienna, and Mus. Nat. Hist. Vienna. Further sources for this material is limited because hardly any contemporaneous outcrop exist beside the stream-bed at Kendl. | |
| Taxonomic list comments:Exhaustive for Mollusca. Nomenclature follows modern usage, with revisions and new taxonomic descriptions in present manuscript. KEY: r - rare; f - frequent; a - very abundant | |
