Both of these fossils are included in the supplementary material here as downloadable virtual models. Both are in the VAXML interchange suggested by Sutton et al. (2012; see also www.spiers-software.org). The models are zipped; when extracted and SPIERS is installed, models can be viewed by double-clicking on the .vaxml files. Low-performance systems may struggle to render the model.
