Abstract

Introduction: Comparable to the conch of extant Nautilus, the ectocochleate ammonite conch is divided into two main parts: the most apertural (anterior) undivided body chamber, which contains the majority of the soft body of the living animal, and the apical posterior) chambered phragmocone. Both are separated from each other by the latest septum. From the last septum to its earliest (embryonic) part (the protoconch), the phragmocone was internally divided in chambers by aragonitic septa. All chambers are connected by the siphuncle, which extends from the protoconch (initial chamber).

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
