Tertiary and Recent marine gastropods include in their ranks a complement of mechanically sturdy forms unknown in earlier epochs. Open coiling, planispiral coiling, and umbilici detract from shell sturdiness, and were commoner among Paleozoic and Early Meso- zoic gastropods than among younger forms. Strong external sculpture, narrow elongate aper- tures, and apertural dentition promote resistance to crushing predation and are primarily as- sociated with post-Jurassic mesogastropods…

The mid-Paleozoic precursor to the Mesozoic marine revolution
TLDR
The mid-Paleozoic radiation of durophages and response of the marine fauna was in many respects similar to events of the Mesozoic Marine Revolution, in effect, the Paleozoic precursor to that event.
Taphonomy and the Mesozoic marine revolution; preservation state masks the importance of boring predators
Exceptionally neomorphosed bivalves from a range of Jurassic sediments from England and North Ireland have been discovered to bear neat, circular, straight-sided boreholes over a millimeter in
Larval ecology and morphology in fossil gastropods
TLDR
Dimensions of internal moulds of protoconchs suggest that planktotrophic larval development was largely absent in the Cambrian and evolved at the Cambrians–Ordovician transition, mainly due to increasing benthic predation.
Predators and Predation in Paleozoic Marine Environments
The Paleozoic body fossil record of potential benthic predators includes nautiloid and ammonoid cephalopods, phyllocarids, decapods, and several lineages of gnathostomes. The latter group, in
The Fossil Record of Shell-Breaking Predation on Marine Bivalves and Gastropods
TLDR
Bivalve and gastropod ecologists and paleoecologists reconstruct predator-prey relationships based primarily on two, although not equally useful, categories of pre-ingestive breakage, namely lethal and sublethal (repaired) damage.
DUROPHAGOUS PREDATION ON MIDDLE JURASSIC MOLLUSCS, AS EVIDENCED FROM SHELL FRAGMENTATION
Abstract:  Durophagous (shell-crushing) predation is known from the beginning of the Phanerozoic, but it has been suggested that modern intensity was not reached until the Late Cretaceous and Early
FISH PREDATION AND THE EVOLUTION OF GASTROPOD SHELL SCULPTURE: EXPERIMENTAL AND GEOGRAPHIC EVIDENCE
  • A. R. Palmer

  • 1979
TLDR
The present study represents the first experimental examination of the types of shell morphologies that offer an effective defense against shell-crushing fishes and rays and test the importance of stout spines as a potential defense against crushing by fish.
Predation on the Pennsylvanian ammonoid Gonioloboceras and its implications for allochthonous vs. autochthonous accumulations of Goniatites and other ammonoids
Damage displayed by 18 of 954 relatively mature (> 35 mm diameter) specimens of Gonioloboceras goniolobum (Meek) from North American Midcontinent Upper Carboniferous sediments is interpreted to be
Paleozoic plankton revolution: Evidence from early gastropod ontogeny
TLDR
A major macroevolutionary trend in gastropod larval shell morphology occurred throughout the middle and late Paleozoic, and most protoconchs were formed by planktonic larvae, and this is the first documentation of a supraspecific trend in Paleozoics invertebrate larvae.
Failed predation in Late Ordovician gastropods (Mollusca) from Manitoulin Island, Ontario, Canada
Shell repairs resulting from presumed failed predation are documented in gastropods from the Late Ordovician (Cincinnatian; Richmondian) mid-to-upper Kagawong Submember of the Georgian Bay Formation

The Fossil Record of Shell Boring by Snails
TLDR
Borings in Paleozoic brachiopod shells (230–550 million years old) that have previously been attributed to gastropod predation are herein attributed to other but unknown boring organisms.
Feeding relationships of teleostean fishes on coral reefs in Kona, Hawaii
TLDR
Feeding relationships ofteleostean fishes on coral reefs a t Kona, Hawaii, were studied during 1969 and 1970, and the situations that prevail throughout day and night are described.
ON THE BIOLOGY AND PALAEONTOLOGY OF SOME PREDATORS OF BIVALVED MOLLUSCA
TLDR
It is suggested that the primary significance of many types of radial ribbing lies not in the ribs themselves, but in the interlocking of the commissure that gave rise to them.
Chapter 7 Trends, Rates, and Patterns of Evolution in the Bivalvia
TLDR
This chapter presents insight into large-scale evolution through the study of a class of animals that is well represented both in the modern world and in the fossil record, the Heteroconchia, which includes the majority of post-Paleozoic burrowing clams.
Interoceanic differences in vulnerability of shelled prey to crab predation
SHELLED gastropods living on intertidal open rocky surfaces exhibit various shell features which can be interpreted as adaptations against such shell-breaking predators as fishes, spiny lobsters, and
THE EVOLUTION OF SPINY LOBSTERS (PALINURIDAE): A STUDY OF EVOLUTION IN THE MARINE ENVIRONMENT

The purpose of this paper is to evaluate relationships in the light of morphological and paleontological evidence, and to propose an evolutionary scheme which accounts for the present distribution of
Post-Paleozoic adaptive radiation of infaunal bivalve molluscs; a consequence of mantle fusion and siphon formation
TLDR
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.

The grazing activities of the tropical echinoid Diadema antillarum Philippi can markedly influence the structure of the shallow-water epibenthic coral reef community. The elimination of an entire
MARINE FAUNAL DOMINANCE AND MOLLUSCAN SHELL FORM
  • G. Vermeij

  • 1974
TLDR
This paper examines in a hypothetical way the possible consequences of a proposed sea-level canal across the Isthmus of Central America in the light of differences in shell architecture among shallowwater marine molluscan assemblages which I believe to reflect differences in the ability to withstand predation.
Trophic model for the adaptive radiations and extinctions of pelagic marine mammals
TLDR
It is suggested that increased upwelling intensity, due to climatic or tectonic events, permitted the initial invasions and radiations and that decreased intensity caused cetacean extinctions in the Oligocene.
