The extent to which animal lineages achieve large body size, a trait with broad advantages in competition and defence, varies in space and time according to the supply of (and demand for) resources, as well as the magnitude and effects of extinction. Using the maximum sizes of shallow-water marine shell-bearing molluscs belonging to nineteen guilds (groups of species with similar habits and food sources) in seven temperate regions from the Early Miocene to the Recent, the present study examined the controls on productivity and predation that enable and compel large size to evolve. The North Pacific (especially its eastern sector) has been most favourable to large-bodied species from the Pliocene onward. Large productive kelps (Laminariales) evolved there in conjunction with herbivorous mammals, setting the stage through positive feedbacks between production and consumption for the evolution of large molluscan herbivores and suspension-feeders. The evolution of bottom-feeding predatory mammals together with other large predators created intense selection for large molluscan sizes. Very large molluscs in the Early Miocene were concentrated in the southern hemisphere, especially among metabolically passive species. Extinctions, which preferentially targeted the largest members of guilds in most regions, were more numerous in the southern hemisphere and the North Atlantic than in the North Pacific. Minimal disruption, together with the early evolution of metabolically-active consumers and the positive feedbacks they engendered, accounts for the evolution of molluscan gigantism in the North Pacific.

“…The second (Beu 2006) reconsidered time ranges and taxonomy of bivalves over this period, including further warm-water migrants. Part 3 (Beu 2010) commenced reconsideration of the time ranges and taxonomy of some gastropods over the same period.The present report is a reconsideration of the time ranges and taxonomy of the remaining gastropods over the same period, with time ranges recorded in oxygen isotope stages (OIS) where possible. Because of space considerations, a number of further gastropods requiring revision have been deleted from this work (partially listed below).…”

“…These characters, however, are also clearly homeomorphic across the family (Merriam, 1941; Marwick, 1957; Kotaka, 1978; MacNeil and Dockery, 1984; Allmon, 1994, 1996). Thus, while detailed morphological examination (e.g., with SEM of protoconch and early apical ontogeny) allows for testing of phylogenetic hypotheses on a limited geographic scale, broader phylogenetic analysis—and reliable assignment to supraspecific taxa—based solely on shell characters remains problematic (Allmon, 1996, 2011; Beu, 2010, p. 89).…”

Turritellid gastropods are important components of many Cretaceous–Recent fossil marine faunas worldwide. Their shell is morphologically simple, making homoplasy widespread and phylogenetic analysis difficult, but fossil and living species can be recognized based on shell characters. For many decades, it has been the consensus that the oldest definite representatives of Turritellidae are from the Lower Cretaceous, and that pre-Cretaceous forms are homeomorphs. Some morphological characters of the present turritelline species resemble those of mathildoids, but many diagnostic characters clearly separate these two groups. We here describe and/or redescribe—based on examination of more than 2600 near complete specimens—four species from the Upper Jurassic Dhosa Oolite Member of the Chari Formation in Kutch, western India, and demonstrate that they are members of Turritellidae, subfamily Turritellinae, on the basis of diagnostic characters including apical sculptural ontogeny (obtained from SEM study), spiral sculpture, and growth line patterns. The four species are in order of abundance, Turritella jadavpuriensis Mitra and Ghosh, 1979; Turritella amitava new species; Turritella jhuraensis Mitra and Ghosh, 1979, and Turritella dhosaensis new species. The turritelline assemblages occur only on the northeastern flank of the Jhura dome (23°24’47.57”N, 69°36’09.26”E). Age of the Dhosa Oolite has recently been confirmed based on multiple ammonite species. All these points indicate that these fossils are the oldest record of the family Turritellidae—by almost 30 million years—in the world.
