Feb 16, 2023 · Experimental results on the fusulinid fossil dataset over five deep learning based milestone models show that OGS using three base models consistently outperforms the baseline using a single base model, and the ablation study verifies the usefulness of each selected view. Jan 1, 2016 · Morphometric procedures to describe fusulinid developmental patterns. • Developmental programs for three fusulinid genera. • Fusulinid life history transitions. • Results suggest a novel interpretation of species with spherical adult test shapes. • These methods are applicable generally to many other fossil and/or recent species. This study supports the assumption that fusulinid individuals of one genus from the same bed in one locality should constitute a single fossil population. To make fusulinid morphospecies more accordant with biological species, it is necessary and reasonable to constrain the conventional determination of fusulinid species with population-level ...There is no definite date for the discovery of the first fossil fuel.
