Reconstructing development of the earliest seed integuments raises a new hypothesis for the evolution of ancestral seed‐bearing structures

This dataset contains three-dimensional model files for <em>Genomosperma</em> specimens LM19 (K1; Long, 1960), LM22, LM1 (L1; Long, 1960), and LM23, supporting the paper ‘Reconstructing development of the earliest seed integuments raises a new hypothesis for the evolution of ancestral seed‐bearing structures' published in New Phytologist https://doi.org/10.1111/nph.16792. These models are saved in a single ZIP compressed folder as four SPV files and also four VAXML datasets in separate folders. All files are labelled with the working/specimen number they represent. SPV files are able to be viewed in SPIERSview, part of the free SPIERS software package (http://spiers-software.org/). The VAXML datasets comprise a VAXML file that provides metadata specifying how to put together accompanying STL files which define the geometry of the objects in the dataset.
