Fossil Ginkgoales cuticle fine details data from East Inner Mongolia, Northeast China.

ABSTRACT

The data presented in this article are related to the research paper entitled "Cuticle ultrastructure of Baiera furcata from Northeast China and its implication in Taxonomy and Palaeoenvironment" (Guignard et al. 2019 [1]. The data correspond to a study of the ultrastructural fine cuticle details of fossil Baiera furcata (Ginkgoales) from the Lower Cretaceous Huolinhe Formation in Holingola of East Inner Mongolia, Northeast China. Two sets of data are provided here 1/ thickness measurements of the layers of four types of cuticles, i.e. ordinary epidermal cells and stomatal apparatus, 2/ ten EDS element analysis of ordinary epidermal cell cuticle layers; the latter data also contain cuticle layers values of Sphenobaiera huangii from the Lower Jurassic Xiangxi Formation in Zigui of Hubei Province, Central China used for comparison in the research article; EDS cell remnant values of Baiera furcata are also included. Some of these data have been used efficiently for taxonomy and palaeoenvironment topics. As they are the first data for genera Baiera and Sphenobaiera of the Ginkgoales, they can serve in the future for considerations of taxonomical comparisons, palaeoreconstructions, palaeoenvironment and evolution.
