Revision of Ordovician chitinozoan Lagenochitina esthonica sensu lato: morphometrics, biostratigraphy and paleobiogeography

Data presented here contribute to the results documented in the paper: Liang, Y., Nõlvak, J., Xu, H., Chen, Y. and Hints, O. (2021) Revision of Ordovician chitinozoan Lagenochitina esthonica sensu lato: morphometrics, biostratigraphy and paleobiogeography. Journal of Paleontology, in press. Two datasets are included, one is Supplemental Data 1 cited in Liang et al. (2021) which contains detailed information of the occurrence data of previously published Lagenochitina esthonica. The other is Supplemental Data 2 cited in the paper which contains two sheets. One sheet named as \"Original data\"and it presents the original raw data of the measurements of Lagenochitina esthonica specimens obtained at the Jägala, Kaldase, Kaugatuma and Baldone sections, eastern Baltica. The other named as \"Two forms\", which divided the raw data into two groups for further statistical study. Statistical morphometric study based on the measurements of L. esthonica indicates that two varieties could be recog...
