Differences in extinction selectivity and their relationship to functional traits in late Cenozoic molluscs

This repository contains all the data and code scripts to replicate the analyses of the paper: Differences in extinction selectivity and their relationship to functional traits in late Cenozoic mollusks. The data is a compendium of functional traits for various species of bivalves and gastropods from the Western Atlantic. Trait data were compiled for 105 species—67 bivalves and 38 gastropods—from the late Cenozoic. For bivalves, six traits were recorded: feeding type, mobility, shell fixation, shell ornamentation, ridge morphology, and organism–substrate relationship. For gastropods, five traits were considered: feeding type, siphonal canal, varix, callus, and umbilicus. Additionally, three traits shared by both clades—life habit, shell composition, and basal metabolic rate—were analyzed across the full dataset.
