Paleoenvironmental and temporal significance of variably colored Paleozoic orthoconic nautiloid cephalopod accumulations

An Early Silurian (Aeronian) cephalopod fauna from Kopet-Dagh, north-eastern Iran: including the earliest records of non-orthocerid cephalopods from the Silurian of Northern Gondwana

“…3) the conchs appear to be either randomly or bimodally distributed on the bedding planes. Histon (2012a) observed that these types of cephalopod accumulations are usually associated with transgressive system tracts within shallow environmental settings with a low sedimentation rate. The contrast between the cephalopod limestones of the Qarebil Limestone Formation and those of younger peri-Gondwana Silurian cephalopod limestones is emphasised by Štěpán Manda (pers.…”

Nautiloid cephalopods from the Rickard Hill facies of the Saugerties Member of the Schoharie Formation, eastern New York, USA (late Emsian, Devonian): A case study in taphonomy from glacial erratics

“…During this event, the RHf fauna was subjected to multiple episodes of exhu-mation and reburial as wave base eroded into the shallow shelf in this localized region of eastern New York during falling sea level and storm events. The resulting concentration of nautiloids and other invertebrate fossils therefore represent time-averaged and post-mortem lag accumulations of hydrodynamically sorted and fragmented exoskeletons (Kidwell and Bosence, 1991;Holland et al, 1994;Brett, 1995;Histon, 2012). Storm events would have also been responsible for reworking brachiopods, corals, and trilobites within the phragmocones and body chambers of nautiloids, as well as associated sediment infilling (e.g., Davis et al, 2001).…”

“…At the same time, palaeontological research was re‐started by studies on bivalves by Kříž (, , ), brachiopods by Plodowski (, ) and Jaeger et al .
