Figure 12 in Classification of Isocrinida (Echinodermata: Crinoidea) with the description of a new extant genus and species from the western Pacific
Figure 12. Constraints to phylogenetic reconstruction and classification of stalked Isocrinida using molecular phylogeny, morphological characters and data from the fossil record. *Complete or at least proximal portion of crown known from the fossil record. The genus Isocrinus is here used 'sensu lato' (Isocrinus + Chladocrinus) as is Metacrinus (Metacrinus + Saracrinus); Cenocrinus is not mentioned because of its uncertain attribution to any of the subfamilies of Balanocrinidae. The Early Cretaceous genus Frasericrinus Ausich et al. 2015 is included within Balanocrinus 'sensu lato'. For the hypothetical attribution to Proisocrinidae of Angulocrinus and Millericrinus, reference is made to the text. Data derive from Hess (Hess 2011a, b), Améziane et al. (2021), and Roux and Philippe (2021). Colours used to differentiate Periods and Epochs are from the RGB Color Code according to the Commission for the Geological Map of the World (Gradstein et al. 2012).

Cellular morphological trait dataset for extant coccolithophores from the Atlantic Ocean
<p>The <strong>Cellular morphological trait dataset for extant coccolithophores from the Atlantic Ocean </strong>is a reference dataset for morphological traits from extant coccolithophores (calcifying marine plankton group), including cell-specific data for coccosphere and cell size, coccolith size, number of coccoliths per cell, and morphometric-based cellular calcite estimates. The dataset also includes ancillary information about the sample and taxonomic identification.</p> <p>The dataset contains observations from 1074 individual coccolithophore cells representing 61 species from 25 genera. Samples were obtained during the Atlantic Meridional Transect (AMT) 14 cruise that sailed between the Faulkland Islands and the UK in 2004. Measurements were taken from scanning electron microscopy (SEM) images, which are archived on Zenodo at doi: 10.5281/zenodo.10571819. A description of the parameters included in the dataset can be found in the file "2. Descriptor- Cellular morphological trait dataset for extant coccolithophores from the Atlantic Ocean".</p> <p>Three additional supporting files are included with this dataset:</p> <ul> <li>"3. Coccolith size, coccolith calcite and cellular calcite in collapsed Umbellosphaera coccospheres" contains measurements of coccolith size (CL) and associated coccolith calcite (PIC) for 20 collapsed <em>Umbellosphaera</em> coccospheres. This data was used to derive an adjustment to coccolith length applied to coccolith length measured on intact <em>Umbellosphaera</em> coccosphere measurements to account for the wide variety of coccolith sizes present on individual coccospheres.</li> <li>"4. Sensitivity of cellular calcite contents to uncertainties in coccolith size, number of coccoliths per cell and shape factors" contains re-calculations of cellular calcite data using uncertainties of ±5-30% on coccolith size (CL) and species-specific shape factor (Ks) and variations of ±2 coccoliths and ±5 coccoliths for the number of coccoliths per cell (CN) for coccospheres of <em>Gephyrocapsa mullerae</em>, <em>Umbilicosphaera hulburtiana</em>, <em>Syracosphaera </em>spp., and <em>Discosphaera</em> <em>tubifera.</em></li> <li>"5. Partial coccolith length and coccolith length measurements" contains measurements used to calculate the uncertainty in coccolith length introduced when partial coccolith length is measured.</li> </ul> <p>Extensive description of the methodology related to this dataset can be found in the associated manuscript: Rosie M. Sheward, Alex J. Poulton, Jeremy R. Young, Joost de Vries, Fanny M. Monteiro, Jens O.
