A fossil record full of holes: The Phanerozoic history of drilling predation
TLDR
The evolutionary history of drilling predation, despite a long and rich fossil record (Precambrian-Holocene), contains a 120 m.y. gap (Late Triassic-Early Cretaceous) as discussed by the authors.Abstract:
The evolutionary history of drilling predation, despite a long and rich fossil record (Precambrian–Holocene), contains a 120 m.y. gap (Late Triassic–Early Cretaceous). Drilled bivalve and brachiopod shells from Jurassic deposits of Hungary, India, and four localities documented in the literature indicate that drillers may have existed continuously throughout the Mesozoic. They may have been descendants of Paleozoic predators, unknown Mesozoic carnivores, or precursors of modern drillers. A literature database suggests three major phases in the Phanerozoic history of drilling predators: (1) the Paleozoic phase (latest Precambrian–Carboniferous) dominated by rare to moderately frequent drillings in brachiopods and sessile echinoderms; (2) the Mesozoic phase (Permian–Early Cretaceous) with very rare, or even facultative, drillers that had little impact on marine benthic communities, but nevertheless may have been present continuously; and (3) the Cenozoic phase (Late Cretaceous –Holocene) dominated by frequent gastropod drillings in mollusks.read more

Ichnology: Organism-Substrate Interactions in Space and Time
TL;DR: In this article, a detailed analysis of the ichnology of a range of depositional environments is presented using examples from the Precambrian to the recent, and the use of trace fossils in facies analysis and sequence stratigraphy is discussed.

Palaeoecology and evolution of marine hard substrate communities
Paul D. Taylor,Mark A. Wilson +1 more
TL;DR: Hard substrate communities are formed by organisms with a variety of strategies for adhering to and/or excavating the substrates they inhabit as discussed by the authors, and they are excellent systems with which to study community evolution over hundreds of millions of years.

The fossil record of predation: an overview of analytical methods
TL;DR: A survey of sampling protocols (data collecting strategy, sieve size, and sample size) and analytical approaches (predation intensity metrics, strategies for evaluating behavioral selectivity of predators, and taphonomic tests) reveals that various approaches can be fruitful depending on logistic circumstances and scientific goals of paleoecological projects as mentioned in this paper.

Autecology and the filling of ecospace: key metazoan radiations
TL;DR: The autecological and taxonomic diversity histories of the marine metazoa appear to be broadly parallel, and future studies of theoretical ecospace utilization should provide more detailed tests of pattern and process in the ecological history of the meetazoa.

Patterns and processes of shell fragmentation in modern and ancient marine environments
TL;DR: In this paper, the authors define a fragment as being a piece of shell having less than 90% of its original form and outline the potential characteristics, pathways, and fates that shells and their fragments can have.

The Mesozoic marine revolution: evidence from snails, predators and grazers
TL;DR: The substantial increase of snail-shell sturdiness beginning in the Early Cretaceous has accompanied, and was perhaps in response to, the evolution of powerful, relatively small, shell-destroying predators such as teleosts, stomatopods, and decapod crustaceans.

The mid-Paleozoic precursor to the Mesozoic marine revolution
TL;DR: 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.
