The origin of the cephalopods from the Monoplacophora is briefly considered. The first rare Upper Cambrian Plectronoceras are now known to be succeeded by a later Cambrian radiation involving the Plectronoceratida, Ellesmeroceratida, and two other orders, all well documented from Chinese occurrences. The greatest success of the nautiloid cephalopods came in the Ordovician Period with three evolutionary pulses in the Tremadoc, Arenig, and later Ordovician. Three particular Palaeozoic problems… Expand
Endocerids: suspension feeding nautiloids?
TLDR
A new hypothesis is proposed and debated: according to it, the endocerids were planktotrophic cephalopods and the largest of them were giant suspension feeders. Expand
An Ordovician nectocaridid hints at an endocochleate origin of Cephalopoda
TLDR
A new nectocaridid is document from the Whetstone Gulf Formation, extending the group's range into the Late Ordovician and indicating a trend towards increased metabolic efficiency through the course of Cambrian–Ordovician evolution. Expand
Epizoic Bryozoans on Cephalopods Through the Phanerozoic: A Review
Cephalopods have a long geological history ranging from the Cambrian to the Recent (Holland 1987; Benton 1993; Kröger et al. 2011) and have provided substrates for many encrusting skeletobionts (seeExpand
Late Cambrian molluscan faunas and the origin of the Cephalopoda
Abstract Late Cambrian gastropod and monoplacophoran faunas from western Antarctica, eastern and mid-western North America, and northern China, are diverse and provide some insight intoExpand
The origins of cephalopod body plans: A geometrical and developmental basis for the evolution of vertebrate-like organ systems
TLDR
The cephalopod body plans are characterized, set against those of the other bilaterians, in the light of recent data from paleontology, embryology, and molecular gene expression patterns to provide a review and new interpretation with an emphasis on the topographic transition of the soft parts that is shaped by a shared concentric circle or ovoid pattern in the embryos and adults of extant or fossil molluscs.

Some observations on bactritid cephalopods
TLDR
The Middle Ordovician genus Eobactrites was probably the first representative of the Bactritida and there is a definite record in the Silurian of the Czech Republic and a possible oc- currence in Northern England. Expand
A Review of Volkhovian and Kundan (Arenig-Llanvirn) Nautiloids from Sweden
Well preserved nautiloid cephalopods dominate diverse macrofossil assemblages in early and mid Ordovician platform carbonates across Sweden (the so-called ‘Orthoceratite Limestone’ lithofacies).Expand

Abstract A reassessment of Glaphyrites material from the Late Carboniferous of Uruguay, famous for being the first ammonite described with the complete buccal mass in situ (also referred toExpand
Evolution of the cephalopod head complex by assembly of multiple molluscan body parts: Evidence from Nautilus embryonic development
TLDR
The results demonstrate that the embryonic organs exhibit body plans that are primarily bilateral and antero‐posteriorly elongated at stereotyped positions, and suggest that extensions of the collar‐funnel compartment and free epidermal folds derived from multiple topological foot regions may play an important role in forming the head complex, which is thought to be an important feature during the body plan transition. Expand
Cephalopod Hox genes and the origin of morphological novelties
TLDR
Developmental expression patterns for eight out of nine Hox genes in the Hawaiian bobtail squid Euprymna scolopes are examined by whole-mount in situ hybridization, showing that Hox orthologues have been recruited multiple times and in many ways in the origin of new cephalopod structures. Expand

The bearing of the new Late Cambrian monoplacophoran genus Knightoconus upon the origin of the Cephalopoda
TLDR
Hypothetical reconstructions of molluscan anatomy support the notion that cephalopods may have been derived directly from a hypseloconid having a high, slightly curved, multiseptate, bilaterally symmetrical shell, by the subsequent development of a siphuncle. Expand

The Middle Cambrian metazoan Wiwaxia corrugata (Matthew) from the Burgess Shale and Ogygopsis Shale, British Columbia, Canada
TLDR
While the possibilities of convergence cannot be eliminated, there appears to be a significant similarity between Wiwaxia and molluscs that suggests a related derivation from a turbellarian ancestor. Expand
