Phylogeny of Paleozoic gastropods and origin of larval planktotrophy

Original language description

A characteristic feature of early Palaeozoic gastropods is the development of a large embryonic shell, reflecting their lecithotrophic larval strategy. The initial whorl of most early Palaeozoic gastropods was openly coiled. This morphology was changed dramatically during the Late Silurian and Early Devonian. The vast majority of those forms was replaced gradually by gastropods developing a relatively small embryonic shell and having tightly coiled initial whorls. This major macroevolutionary trend in larval shell morphology coincided with the inception of larval planktotrophy, and was followed by the late Paleozoic radiation of Neritimorpha, Caenogastropoda, and Heterostropha. The inception of larval planktotrophy also coincided with fundamental changes in the biogeochemical evolution of the Palaeozoic oceans, and seems to have been closely linked to a pronounced increase of nutrient input to sea-surface waters during the Palaeozoic eutrophication episodes.
