Failed prey or peculiar necrolysis? Isolated ammonite soft body from the Late Jurassic of Eichstätt (Germany) with complete digestive tract and male reproductive organs [PDF]
Ammonoid soft parts have been rarely described. Here, we document the soft parts of a perisphinctid ammonite from the early Tithonian of Wintershof near Eichstätt (Germany). This exceptional preservation was enabled by the special depositional conditions

An ammonite trapped in Burmese amber [PDF]
SignificanceAquatic organisms are rarely found in amber, but when they occur they provide invaluable evidence for the better understanding of amber taphonomy and past ecosystems. We report an ammonite and several marine gastropods alongside a mixed assemblage of intertidal and terrestrial forest floor organisms in mid-Cretaceous Burmese amber.

New evidence from exceptionally “well-preserved” specimens sheds light on the structure of the ammonite brachial crown [PDF]
Ammonite soft body remains are rarely preserved. One of the biggest enigmas is the morphology of the ammonite brachial crown that has, up till now, never been recovered.

Cenomanian Ammonite Zones [PDF]
A preliminary statement is made concerning the ammonite genera which have been used in defining the upper Cenomanian (Cretaceous) in Britain. The relations, positions, and characteristics of species of Mantelliceras, Metoicoceras, Utaturiceras, and Protacanthoceras are briefly explained and the need for a change in zonal nomenclature of the uppermost ...

Sedimentary Mercury Enrichments as a Tracer of Large Igneous Province Volcanism
Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Biostratigraphy of the Cretaceous deposits based on ammonites in the southwest of Qayen area (Qumenjan section) [PDF]
Ammonite biostratigraphy could be used in age determination and correlation of rock units in different sedimentary basins. Qumenjan section with 125 meters thickness is mainly formed by grey sandy limestone with grey and thick-bedded limestone ...

Ammonites and stratigraphy of the Achdorf Formation (Braunjura Group; Aalenian) at the Wochenberg hill near Schömberg-Schörzingen (W Swabian Alb, SW Germany) [PDF]
In sections of the Achdorf Formation at the Wochenberg hill (western Swabian Alb, SW Germany), a succession of five ammonite biohorizons is distinguished (from bottom to top): the crassicostatum and viallii biohorizons of the Lower Aalenian (Bifidatum ...
