Inferring palaeoecology for fossils is a key interest of palaeobiology. For groups with extant representatives, correlations aspects body shape ecology can provide important insights to understanding extinct members lineages. The origin and ancestral turtles debated various shell or limb proportions have been reported correlate habitat among turtles, such that they may be informative inferring the fossil including early shelled stem turtles. One recently described method proposes simple measurements effectively quantify doming plastron width differentiate classes in linear discriminant analysis, whereby aquatic low domed shells narrow plastra. respective study unorthodox predictions lifestyles turtle Proganochelys quenstedtii meiolaniform Meiolania platyceps, terrestrial habits Proterochersis robusta. Here, we show these published results are consequence questionable methodological choices as omission species data which do not conform preconceived shape-ecology association. When reversed, corrected, phylogenetic flexible analysis applied, cannot correctly predicted based on measurements. This invalidates well proposed palaeohabitats fossils.
