Cephalopod origin and evolution: A congruent picture emerging from fossils, development and molecules
TLDR
A growing body of evidence from the fossil record, embryology and Bayesian molecular divergence estimations provides a comprehensive picture of cephalopods' origins and evolution.
Diversity, Morphology, and Phylogeny of Coleoid Cephalopods from the Upper Cretaceous Plattenkalks of Lebanon–Part II: Teudopseina
TLDR
A detailed comparison with Jurassic gladii shows that the Teudopseina is a very homogenous group that can be easily differentiated from other Mesozoic, gladius-bearing groups (Prototeuthidina, Loligosepiina).
NEW OCTOPODS (CEPHALOPODA: COLEOIDEA) FROM THE LATE CRETACEOUS (UPPER CENOMANIAN) OF HÂKEL AND HÂDJOULA, LEBANON
TLDR
The surprising existence of a stylet‐like gladiusige in Styletoctopus annae sp.
Diversity, Morphology, and Phylogeny of Coleoid Cephalopods from the Upper Cretaceous Plattenkalks of Lebanon–Part I: Prototeuthidina
Abstract Morphologic analyses of a large collection of coleoid cephalopods from the Lebanese Upper Cretaceous yielded a much higher diversity than previously assumed and revealed numerous
Gladius shape variation in coleoid cephalopod Trachyteuthis from the Upper Jurassic Nusplingen and Solnhofen Plattenkalks
TLDR
Morphometric analyses have shown that length−width indices are ambiguous characters to differentiate between the three species of Trachyteuthis hastiformis, which can be linked with the Early Jurassic genus Teudopsis and the Late Cretaceous genus Glyphiteuthis.
Molecular clocks indicate turnover and diversification of modern coleoid cephalopods during the Mesozoic Marine Revolution
TLDR
Divergence estimates highlight the modern diversity of coleoid cephalopods emerging in the Mesozoic Marine Revolution, a period that also witnessed the radiation of most ray-finned fish groups in addition to several other marine vertebrates.
Ancestry, Origin and Early Evolution of Ammonoids
TLDR
In order to put the origin of the Ammonoidea into the broader evolutionary context, this work reviews the hypothesis on theorigin of cephalopods in general, the originof bactritids as well as the origin and major morphological changes that occurred until the early evolution of ammonoids.
