This paper introduces the Ordovician bivalves of southern China to non‐Chinese colleagues, and then incorporates them into the global Ordovician bivalve database compiled by Cope ( 2004 ). This will provide a firmer basis for the discussion of the initial adaptive radiation of the Bivalvia. A new scenario for the early evolution of the class Bivalvia is advanced herein based on the integration of a wide variety of evidence concerning bivalves, including morphological features, ontogenetic… 
The early bivalve radiation in the Ordovician Gondwanan basins of Argentina
Recent discoveries of Tremadoc to early Darriwilian bivalves from the NWA and Famatina basins indicate that the dominance of higher groups (e.g. Heteroconchia, Pteriomorphia) deviates from the patterns evident in other Gondwanan basins, agreeing with previous ideas supporting the importance of local radiations during the Ordovician diversification.
Chapter 16 The Lower Palaeozoic palaeobiogeography of Bivalvia
Abstract Bivalves first appeared in the Early Cambrian and were virtually cosmopolitan. These very small and insignificant molluscs were probably surface crawlers on the microbial mat floors of the

A Darriwilian (Middle Ordovician) Bivalve-Dominated Molluscan Fauna from the Stairway Sandstone, Amadeus Basin, Central Australia
A bivalve-dominated molluscan fauna is described from the Darriwilian (Middle Ordovician) Stairway Sandstone, Amadeus Basin, central Australia. The fauna comprises 16 species of bivalves and

Burrowers from the Past: Mitochondrial Signatures of Ordovician Bivalve Infaunalization
Selective signatures on bivalve and gastropod mitochondrial genomes with respect to a time calibrated mitochondrial phylogeny are investigated by means of dN/dS ratios, detecting a major signal of directional selection between the Ordovician and the Lower Devonian for bivalves mitochondrial Complex I and an overall higher directional selective pressure onbivalve Complex V withrespect to gastropods.
Affinities and palaeobiogeographical significance of some Ordovician bivalves from East Yunnan, China
Comparisons between the eastern West Yunnan fauna and those of Western Europe, where glyptarcids are also important members of the fauna, suggest that the easternWest YunnanFauna lay at a much higher palaeolatitude than the East Yunnanfauna.
The Effect of Taxonomic Corrections on Phanerozoic Generic Richness Trends in Marine Bivalves with a Discussion on the Clade's Overall History
The new generic taxonomic curve is comparable with the trajectory of the Sepkoski's modern fauna and shows rapid and substantial diversification through the Ordovician, followed by a Paleozoic plateau, aMesozoic high, and Cenozoic diversification after a small reduction in richness associated with the K/Pg extinction.
Upper Darriwilian (Middle Ordovician) Radiolarians and Ostracods from the Hulo Formation, Zhejiang Provicnce, South China
Considerable research has been done on the Ordovician marine fossils from South China, including macrofossils such as brachiopods, graptolites, bivalves, trilobites, some microfossils like conodonts

Adaptive Themes in the Evolution of the Bivalvia (Mollusca)
The present goal is to distill from the evolutionary record of the Bivalvia, via functional morphology, certain basic adaptive tendencies and patterns that seem, at the present state of knowledge, to be most fundamentally characteristic of the evolution of this important class of mollusks.
Post-Paleozoic adaptive radiation of infaunal bivalve molluscs; a consequence of mantle fusion and siphon formation
The radiation of infaunal bivalves in terms of life habits has revealed that the preponderance of new Mesozoic and Cenozoic groups were bur- rowers and borers that fed by means of siphons, whereas siphon feeders had been virtually absent in the Paleozoic Era.
Diversification, Faunal Change, and Community Replacement during the Ordovician Radiations
The Ordovician evolutionary radiations represent a major pivotal point in the history of life on earth. During the few tens of million years between the ends of the Cambrian and Ordovician Periods,
Evolution of the deep sea protobranch bivalves
The number of protobranch species of the continental shelves of the world comprise between 10 and 15 % of the total number of bivalve species present. This is in contrast to the bivalve fauna of the
Modeling bivalve diversification: the effect of interaction on a macroevolutionary system
Results of this analysis suggest that interactions with other taxa have substantially affected bivalve global diversity through the Phanerozoic, particularly during the initial Ordovician radiation and following the Late Permian and Late Cretaceous mass extinctions.
Association of orogenic activity with the Ordovician radiation of marine life.
Results indicate that genera that belonged to an array of higher taxa that diversified in the Middle and Late Ordovician were far more diverse in, and adjacent to, foreland basins than they were in areas farther removed from orogenic activity (carbonate platforms).
